Windows 10 laptop slows down a lot what to do


The processor power of a dual-core laptop is drained by applications running in the background.

Eliminating the cause: View running programs in the task manager. Stop and delete not used by you. Replace the required CPU-intensive programs with the ones that work correctly. Do it carefully and if you are not sure, then contact more experienced people.

Registry entries

Slow operation of the laptop is facilitated by a large number of programs in the startup of the operating system.

Eliminating the cause: Remove unnecessary programs from startup. All programs in use are displayed on the lower right side of the laptop screen when you press the Start button. For prevention, use programs that correct entries in the registry.

For example, WinHacker 95. changes icons, renames and deletes service folders, varies various Windows settings.

Win-eXpose-Registry. monitors calls to the Registry with the ability to filter by the type of calls. You can print the log file from the program, but you cannot save it to the desired location. Also, you cannot navigate to a modified, created, or deleted key.

Registry Search Replace. views and replaces parameters in the Registry not only of the local, but also of the remote computer, and in keys of certain types, with the subsequent saving of all settings.

Defragment your hard drive

Open Disk Defragmenter. To do this, click the Start button. In the search box, type Disk Defragmenter, and then select Disk Defragmenter from the list of results. In the Current Status section, select the drive you want to defragment.

To determine if disk defragmentation is required, click Analyze. If you are prompted for an administrator password or confirmation, enter the password or provide confirmation.

When Windows finishes analyzing the disk, the Last Start column will show the percentage of disk fragmentation. If this value is more than 10%, you need to defragment the disk.

Click the Disk Defragmenter button. If you are prompted for an administrator password or confirmation, enter the password or provide confirmation.

10 reasons why laptop is slow

Many users face the problem of slow laptop performance. Here are ten main reasons why a laptop takes a long time.

Operating system

The operating system and hard drive become overwhelmed with information over time. When the laptop is running, the programs used are not always removed correctly. This leads to various conflicts in the operation of the system. The more programs are installed and running at the same time, the higher the likelihood of crashes leading to slower laptop performance.

Eliminating the cause: It is recommended to regularly use programs for complex maintenance of the operating system registry in order to avoid this problem. For example, Reg Organizer. multifunctional program for complex maintenance of the system registry Micorosoft Windows. Carries out cleaning of the registry, its compression and defragmentation. It also has a registry editor and an advanced search and replace data function, previews imported reg-files (including from Explorer). Reg Organizer performs a complete removal of the software, cleaning up all the “tails” remaining in the system after the usual uninstallation.

Virus check

There are viruses that do not manifest themselves for a long time. But in the active phase, they slow down the laptop.

Eliminating the cause: run the antivirus program.

Open the main window of the antivirus program, go to the “Scan hard drives” or “PC scan” menu. In the window that appears, define the scan settings for your computer.

For a more thorough scan, choose the most powerful option. “Deep Scan”. After that, we indicate the hard drives and other devices on which we will search for and remove viruses.

If necessary, we can fine-tune the scanning and file checking parameters. After that we press the button “Scan”.

During the scan, the antivirus will detect suspicious files and then offer to perform one of the actions on them. Usually antivirus offers:

  • deleting a file;
  • moving a file to quarantine;
  • skip the file (leaving everything unchanged);
  • clean the file from viruses.

Select one of the actions and press the “Ok” button.

If the virus remains on the computer after running the anti-virus program, you must remove it yourself. We indicate the name of the file to be deleted to the anti-virus program. To do this, open the folder in which the damaged file is stored, and click on it with the right mouse button and select one of the actions in the menu that appears (for example, “Check for viruses”).

In the event that the antivirus did not find suspicious data in the file or several files, but you know that the file contains a virus, select this file or several files and press the shift del combination.

Hard disk sector

The reason for the slow operation of the laptop is the appearance of bad sectors on the hard disk. This is a “disease” of laptops that are more than two to three years old.

Eliminating the cause: Periodically check the disk for bad sectors. The built-in Windows disk surface diagnostic tools will help you with this. Just as effective is third-party software.

File fragmentation

The laptop needs periodic defragmentation to help sort and organize the logical partitions of the disk on which the operating system files are located.

Eliminating the cause: Defragmentation is best done with specialized programs.

Why Windows 10 slows down on a new laptop?

Many owners of new inexpensive laptops face a similar problem. Having come home and connected it to the Internet, users cannot understand why it slows down so much. Slowdown manifests itself in everything: when opening programs, viewing sites and videos on the Internet, when working with text documents.

Why this is happening and how to fix this problem, you will learn in this article.

What to do and how to at least partially correct the situation?

Many people may think of a really good idea at first glance. why not reinstall Windows 10 on Windows 7 ?! We answer. Yes, that would really help, but there is one problem. The fact is that almost all laptops released since 2017 do not support Windows 7. It is very easy to check this. It is enough to go to the official support site for your laptop, select your model, go to the section with drivers and open the list of available operating systems.

Checking the operating systems supported by the laptop on the official website

If there is only Windows 10 there, then you should not try to install Windows 7, because even if you succeed in doing this, then there will definitely be problems with the drivers. With a 99% chance the touchpad and USB ports will not work.

Thus, the only option is to configure Windows 10 and disable resource-intensive services to reduce the load on laptop components.

What can be disabled?

The first step is to turn off updates. This will significantly reduce the load on the hard drive and on the Internet connection. Websites will start to open much faster.

To do this, open computer control by right-clicking on the “Start” menu and go to the “Services” section.

A list of all operating system services will open on the right side of the window. We are interested in “Windows Update”.

Disable automatic start of the update service

Click on it twice with the left mouse button. A window will open in which you need to set the startup type “Disabled” and be able to press the “Stop” button.

The same should be done with the “Windows Search” service. Disabling it will also have a positive effect on the performance of the hard disk, which will lead to less braking of the laptop.

Disable indexing service to speed up laptop on Windows 10

If, after all of the above, the inhibition is still present, then the next step is to try to remove the antivirus. Why him? Because Windows 10 has a built-in antivirus. Windows Defender. And installing a third-party antivirus like Kaspersky or Avast slows down your laptop even more. Two antiviruses try to work in parallel, which inevitably leads to slowdown on weak computers.

In the absence of a positive result, the last thing that can be advised is to install an SSD instead of the hard drive. It will cost about 60 if you install a 120 GB SSD. But the effect of this procedure will be huge. Laptop speed will grow exponentially.

Reasons for slow performance of a new laptop on Windows 10

Immediately, we note that this has nothing to do with the licensed Windows you have installed or pirated. Even laptops with a preinstalled version of the operating system slow down.

As a rule, a combination of factors leads to slow work, namely:

  • Slow processor and hard drive, which are found in inexpensive laptop models;
  • Continuous operation of the update service, which consumes a huge amount of hard disk resources and the Internet channel;
  • The presence of other active services in Windows 10 that place a load on laptop components. This load leads to the fact that there is simply no computing power left for your tasks.

Don’t buy the cheapest laptops. Cheap ones mean laptops with a cost of about 250. 300. If you still became the owner of a new, but lagging laptop on Windows 10, then we advise you to disable the system update service, the indexing service (Windows search), remove the third-party antivirus, if any, and replace SSD hard drive.

Downloading the correct drivers

The problem faced by many users of laptops with Windows 10. Creation of drivers for the gadget should be handled by the company that collected it. But a year after the release of the “dozens”, many manufacturers still have not provided actual drivers, or they release them only for new laptop models.

If your laptop slows down after upgrading to Windows 10, download and install drivers for your device.

Why the laptop slows down, how to fix

A laptop with Windows 10 makes a person mobile and at the same time takes advantage of all the advantages of a stationary PC. But unlike a computer, these devices are more likely to “glitch”. If you do not know why the laptop slows down, what to do to make Windows 10 work efficiently, use the tips described in this article.

Cleaning the hard drive

After upgrading to Windows 10, the files of the old OS version remain on the system drive. They are used if the user decides to “roll back”, but because of them the hard disk becomes full. If you are confident that you will not be returning to an old OS, delete these files. How to do this is described in the article “How to completely delete the Windows.old folder on a Windows 10 computer?”.

For stable operation of Windows 10, you need 8-10 GB of free space on the system disk (twice the amount of RAM). Therefore, delete / move unnecessary files to other drives or cloud storage.

Why the laptop slows down

Developers are trying to make Windows 10 as feature-rich and productive as possible. But sometimes, after upgrading to “ten”, the laptop starts to slow down. It interferes with work and play. This also happens with devices on which the OS is initially installed. Causes:

  • autoload is not optimized;
  • incompatible drivers;
  • overheat;
  • the hard disk is full;
  • incompatible programs.

On the manufacturer’s website

  • Open the website of the laptop manufacturer → enter the laptop model in the search bar → Support → Drivers and Utilities.
  • Specify the type of operating system (bit Windows 10) → download and install all available drivers.

Optimization of startup

A user who buys a new laptop may have a huge number of additional programs from the device manufacturer installed by default. They run automatically along with the OS and mostly run in the background.

    Right-click on the Taskbar → Device Manager → Startup tab.

Weak computer

The main reason why a laptop with Windows 10 starts to slow down is its “weak” technical parameters. Manufacturers are trying to adhere to Microsoft’s recommendations regarding the minimum technical requirements for devices on which the “ten” will work. When an ordinary user updates or installs a new OS on his own, he rarely looks at the recommendations.

Windows 10 minimum system requirements:

  • processor with a clock speed of 1 GHz or higher or single-chip system (SoC);
  • RAM: 2 GB for new devices, 1 GB (32-bit) or 2 GB (64-bit) when upgrading;
  • free disk space: 16 GB (32-bit) or 20 GB (64-bit);
  • screen resolution 800 × 600 pixels;
  • video adapter supporting DirectX9 or higher or WDDM version 1.0.

If the laptop does not meet the minimum requirements or is close to them in value, Windows 10 will slow down and work incorrectly.

What to do if your laptop slows down

There are other reasons why the device is performing slowly or incorrectly. Some of them are eliminated (read “WhySoSlow will help you understand why the computer is slow”).

The first reason why even a new laptop with Windows 10 installed slows down. problematic drivers

A new laptop doesn’t mean properly tuned for maximum performance, especially if you’ve upgraded to Windows 10 yourself.

The fact is that when updating, drivers can be downloaded from the Microsoft Center, and this is far from the best service for installing them.

Please note that it is the drivers that are responsible for the operation of all laptop devices. without them, neither here nor there, and the most effective update is the manufacturer’s website. Only there you can download the most efficient.

Overall, laptop performance is not the result of one reason. Windows 10 slows down very badly, usually due to a combination of small reasons.

For example, the system is not optimized, viruses, dust, ineffective cooling, non-fragmented files, dozens of startup programs and many other factors have settled in the system; this is the standard state of an average laptop 2-3 years after purchase.

However, this article focuses on sudden, hard braking of your laptop and loss of performance after updating Windows 10.

The second recommendation is what to do if the laptop starts to slow down strongly. viruses

Even if you have, in your opinion, the best antivirus installed, you will never be 100 percent protected from the invasion of malware.

What to do? I always suggest using the curing utility (with Russian and free) for checking. doctor web.

Also, if you are not lazy, you can search the net, download and install the free program “ComboFix”. its use is a pretty good option in many situations.

Remember. any, even the most invisible virus, even a harmless one, slows down a laptop on all Windows, including 10. as a result, the system starts to slow down.

recently, a new type of virus called bitcoin and cryptocurrency has grown in popularity.

Their goal is to use the computing power of the computer, as a result of which symptoms of inhibition appear.

Other viruses can act in the same way. This is by far the most common cause of a fairly sudden laptop slowdown.

The third reason why Windows 10 slows down. autoload

The startup contains programs that start when Windows 10 starts.

If there are a lot of them, then naturally a heavy load will turn out and the resources of the laptop will be exhausted.

I remember recently I was asked to check why games slow down when the processor and video card are the most modern.

Everything turned out to be in autoload. after its optimization, the performance was fully restored.

5 reasons why the laptop began to slow down very much after updating Windows 10

If your laptop, even a new one after upgrading to Windows 10, began to slow down very much, programs start much longer than usual, a sign that something is wrong with it.

In some cases, it can even lead to hardware damage, loss of files or the security of your personal data.

Therefore, it is best to take care of this as soon as possible. What to do? This article assumes that you are at least intermediate users and know what you are doing.

Remember that any changes you make to your laptop are at your own risk.

If you are afraid that the situation will worsen, you can always count on help in the comments.

Here are five top reasons why your laptop is slow and troubleshooting tips.

The fourth recommendation is what to do if Windows 10 lags. hardware

This section is not specifically related to Windows 10, but more to the hardware elements of the laptop.

These are the hard drive, processor, video card and RAM. With a weak one of these components, the laptop will start to slow down, no matter how powerful all the others are.

Only with a properly configured PC system can it show an excellent performance result.

Some hardware configurations can actually automatically reduce the frequency of the processor in case of overheating so as not to damage it.

If you find something similar, then your search for a solution to the problem should be directed to the cooling system.

Checking the cooling is somewhat more difficult and depends on the type and design of the computer.

What everyone can do for himself is to assess wind turbines and the degree of dust on visible cooling elements.

Cooling problems can quickly lead to extensive equipment damage, so they should not be ignored.

Other reasons why Windows 10 slows down in a laptop. the fifth recommendation

If you have done all of the above and nothing has changed in the laptop, you need to look at the problem deeper and perhaps spend a little more time finding it.

On the system partition of the hard disk, you must have at least 20% free space (this is a prerequisite for the efficient operation of the system).

Defragmenting the hard drive will also not hurt (you will need to leave the computer alone for a few hours).

Disconnect your laptop from the internet and turn off all background programs, including anti-virus programs. If there are no improvements, turn on the antivirus and move on.

Remove the latest updates and changes to the system. You can use system restore points, only on Windows 10 this feature is disabled by default (you need to use it yourself).

It should be added that reinstalling (reinstalling) Windows 10 does not always solve the problem, because there is a possibility that the reason for the slowdown is hardware related.

This stage requires significant experience and in-depth knowledge of the operation of the hardware and operating system, so the smartest and fastest way is to take advantage of professional computer service.

I recommend using diagnostic software that shows key, detailed information about the configuration of the laptop’s hardware.

In most cases, the free CPU-Z tool is sufficient. With it, you will find out the parameters of the processor, graphics chip, motherboard and RAM. Success.

HDD fragmentation

Unlike solid-state drives, hard drives such as HDDs are prone to fragmentation, the degree of which increases in proportion to the number of operations to delete old files and write new ones. If your laptop has an HDD, check the file system status from time to time and defragment if the fragmentation of files on partitions is more than 10 percent.

Infecting your computer with viruses

Malicious programs, in particular, miners, can significantly reduce the speed of work due to their consumption of computer resources. The classic scenario when everything was in order, but after installing the program, a laptop with Windows 10 began to slow down. What to do in this case? Naturally, remove the software, after the installation of which problems began, and thoroughly scan the system with at least two antivirus scanners.

Windows 10 laptop lags badly. what to do?

Very often, some time after installation on a laptop, Windows 10 starts to work slower. the desktop load time increases, applications start not so quickly, and resource-demanding games begin to lag. Minor slowdowns of a Windows 10 laptop are usually caused by natural causes, for example, errors that accumulate over time, new applications and services added to startup, disk fragmentation, etc.

A drop in performance can also be observed when system services, built-in and third-party applications work incorrectly, there are errors in service packs, and the requirements for hardware and software do not match. But this, of course, if you generalize. In reality, identifying the source of the problem is not always easy; this requires at least a comprehensive check of the device. So, why Windows 10 laptop slows down and how to speed up it?

Garbage in the file system

Try not to fill the hard drive with files to the eyeballs. this not only slows down the read / write speed, but also not in the best way affects the life of the drive.

Hard disk wear

Among the reasons for the deterioration in the performance of Windows 10 is the general wear and tear of the hard drive. The presence of logical errors, and especially bad sectors, slows down the read / write speed, leads to freezes when opening large files, a system crash in a BSOD, or even a sudden shutdown of the computer (if bads fall on the system volume). We recommend checking the hard disk with programs like CrystalDiskInfo.

Braking can also be observed in case of malfunctions in the operation of the RAM. It should also be tested.

Overheating of hardware components

Laptops do not have a sufficiently efficient cooling system, which is why their hardware components often overheat. Excessive overheating in turn leads to reduced performance. After determining the temperature of key components using AIDA64 or another similar utility, take appropriate measures if necessary. clean the laptop from dust, replace, if necessary, thermal paste and adjust the fan speed using special software.

Outdated or incorrectly working drivers

If a decrease in performance is observed after replacing components or connecting external devices, you should check the status of the drivers and, if necessary, update them to the latest versions. By the way, driver incompatibility gives an answer to the question of why a new laptop with Windows 10 slows down. The fact is that to ensure the operation of devices in Windows 10, Microsoft drivers are used, which are not always suitable for a specific hardware configuration. Therefore, you need to download drivers from the official websites of device manufacturers. However, you can always use DriverPack Solution or a similar tool to update your drivers.

Blocked startup

The presence of a large number of programs at startup is the most common reason for a slowdown in system performance. It’s easy to see which programs start with Windows 10, just open the Task Manager and switch to the “Startup” tab.

Using the same Manager, users can disable automatically loaded applications and modules. To remove unnecessary programs from startup, you can also use third-party tools like CCleaner.


Startup is those programs, utilities that run along with the operating system. Because of this, the OS may load more slowly, and in the process, you may notice that your Windows 10 computer starts to slow down, lag or glitch. As a rule, 90% of what hangs in startup is simply unnecessary. Now we’ll try to turn everything off.

You need to go to the “Task Manager”. To do this, just press the “CtrlShiftEsc” keys. You can also click on the work panel, which is located at the very bottom, with the right button.

Now go to the “Startup” tab. You can disable almost everything except Realtek HD Manager and your antivirus software. Everything else is simply unnecessary, and will start in the event of the next launch of an application. Many people also leave the “nVidia” and “AMD” panels, confusing them with drivers, but they can also be safely disabled.

NOTE! All major drivers are launched even before the desktop is displayed when the system boots, and they are not in the “Startup”.

At the very end, we reboot. If some of the programs remain in startup, then they are hanging in the registry. They can be removed from there yourself, or removed from the laptop altogether.


Outdated, or even worse, irrelevant drivers can not only slow down the system, but also periodically throw out the “blue screen of death”. This happens when drivers from the 7th or 8th version of Windows are installed on the top ten. they may or may not work (how lucky you are). Therefore, now we will not wonder whether we have installed the correct drivers, but install the new pack again.

Random access memory

Many users began to complain about the brakes after updating the Windows 7 or 8 operating system to the top ten. Most often, the reason is quite commonplace. the PC does not have enough RAM. If 8 gigabytes of “RAM” are enough for a 7, then for 10, in my opinion, for normal operation there should be at least 16 GB. For satisfactory work, 10-12 GB may be enough.

ATTENTION! If you have 16 GB of RAM or more, then I advise you to follow the instructions that I wrote below. You need to remove the “swap file” from all drives.

Until you bought it, there is one little “life hack”. to use a “swap file”. This function will slightly speed up the system and help to remove the shortage of RAM.

  • Again, go to “Additional system parameters”.
  • We go to the “Parameters” performance.
  • On the “Advanced” tab, click “Change”.
  • For the “C” drive, indicate the missing size.

NOTE! If you have 16 GB of RAM or more, then turn off the paging file for both disks, since it works slower than RAM. it will slow down the program and the OS.

A computer

Remove the side cover and use a vacuum cleaner to completely clean the system. We pay special attention to coolers and radiators. After that, we remove the main heatsink from the processor and change the thermal paste on it.

Disable CFG (Control Flow Guard)

The “Control Flow Guard” function dramatically slows down the system, as it constantly monitors the laptop’s memory. The threat is not super serious, plus you already have an antivirus program.

  • Options. Updates & Security. Windows Defender.
  • Open the section “Application and Browser Management”.
  • Click on the link: “Exploit protection settings”.

Checking the hard drive

If you have an old or even a new laptop, then with a strong system load, you need to check the hard drive. There are two symptoms of a broken hard drive:

  • The system takes a very long time to boot, but with a large amount of RAM, it continues to work normally. If the RAM is less than 10 GB, then the laptop slows down constantly.
  • When you turn on and boot the system or work with conductors, you hear a distinct grinding.

Either way, the hard drive is worth checking out. There are tons of free programs for this. My favorite is the Victoria HDD. There is nothing complicated. download, run the check and wait for the result. In the “Smart” tab in the row, you will see the overall rating. If the value is “BAD”, then you should think about replacing the hard disk.

windows, laptop, slows, down


This service acts as a firewall that blocks unwanted attempts to compromise the system. The problem is that during normal operation of the antivirus program, this service is not needed. You can try to disable it. This is done through the registry editor (WinR = regedit). We pass along the path:

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrenTVersion \ Explorer

We find the parameter “SmartScreenEnabled”. open it and set the value “off” (with a small letter). We save the parameter and restart the computer.
