Microsoft has promised improved performance with Windows 10, and even though many users report improved performance some are claiming that Windows 10 has slowed down their system, so let’s explore this issue.
Windows 10 is slow, how to fix it?
One of the most annoying problems that you can encounter are slowdowns. These issues can be problematic, and speaking of which, these are some of the most common issues the users reported:
- Windows 10 very slow startup – Many users reported that Windows 10 has a slow startup. This is most likely caused by your startup applications, and in order to fix that, you need to find the problematic applications and prevent them from starting with your PC.
- Windows 10 very slow and unresponsive – This is another problem that can occur on Windows 10. However, you should be able to fix it using one of our solutions.
- Slow Windows 10 after update – Sometimes a certain update can cause this issue to appear. If that happens, it’s advised to remove the problematic update and check if that solves the problem.

Solution 1 – Check for viruses
Just like any other Windows system, Windows 10 is vulnerable to viruses, so make sure that your system is clean. You can download any free antivirus software and do a full system scan just to be sure.
If you want to ensure that your PC is safe and protected from malware, you might want to consider some of these tools. Bitdefender, BullGuard, and Panda Antivirus are currently the best antivirus solutions available, and if you suspect that your PC is slowing down due to malware, be sure to download and install one of these tools and use them to scan your PC.
Solution 2 – Disable heavy performance processes
Sometimes third-party applications can cause Windows to become slow. To ensure that third-party applications aren’t slowing down your startup, you need to disable them by doing the following:
- Open Task Manager by pressing Ctrl + Shift + Esc on your keyboard.
- When Task Manager opens go to Startup tab. Sort the processes by their Startup impact rating.
- Disable processes in the High category, but don’t disable crucial programs such as your antivirus.
Solution 3 – Enable faster startup option
It seems that Microsoft has added a new feature called Hybrid Startup and Shutdown that puts your PC into a hibernation state and improves the startup and shutdown process. This option might consume bit more power because it doesn’t turn off your computer completely, so keep that in mind. To enable faster startup, do the following:
- Press Windows Key + S and enter power settings. Select Power & sleep settings.
- Click the Additional power settings.
- Click on Choose what the power button does from the menu on left.
- Now select Change settings that are currently unavailable.
- Make sure to check Turn on fast startup (recommended).
- Save your changes and you’re good to go.

- Press Windows key + R and type services.msc and press Enter.
- Services Window should open, and it will reveal the list of all services that are starting with your Windows 10. Look for any services that take too long to launch.
- Find those services on the list, right click them and change the settings from Default to Delayed Start.
- Save your changes and restart.
Solution 5 – Disable blur effects and transparency
Sometimes these effects can have their toll on your performance so you might want to disable them.
- Open the Settings app.
- Then click on Personalization.
- Next click on Colors. Set Transparency effects to Off.
Solution 6 – Perform a clean Windows 10 install
Sometimes there are software issues when you upgrade from Windows 8 or Windows 7 to Windows 10, so it’s advised that you perform a clean install of Windows 10. Just be sure that you backup your important files before doing this.
Solution 7 – Use CCleaner
If your Windows 10 is slow, the problem might be your temporary files or your registry. According to users, you can easily fix this problem simply by removing these files from your PC. Doing that manually can be a tedious process, but you can automatically delete these files as well.
One of the best applications that can remove temporary files and optimize your registry is CCleaner. Many users reported that they fixed the problem by using CCleaner on their PC, so if your Windows is slow, be sure to try using this tool.
Solution 8 – Stop Windows Module Installer service
According to users, if your Windows is slow, the issue might be Windows Module Installer service. This service is related to Windows Update, and by disabling it, you might not be able to download updates, so keep that in mind.
To disable this service, do the following:
- Press Windows Key + R and enter services.msc. Now press Enter or click OK.
- Services window will now appear. Locate Windows Module Installer on the list and double click it to open its properties.
- Check the Service status, if it’s set to Running click the Stop button to stop the service. In addition, you can also change the Startup Type to Disabled if you want to permanently disable this service. Now click on Apply and OK to save changes.
After disabling this service, check if the problem is resolved. Keep in mind that by disabling this service you might not be able to receive Windows updates, so be sure to enable it any other problems occur.
Solution 9 – Disconnect all peripherals
Sometimes your hardware can cause Windows 10 to become slow. To fix that problem, you need to disconnect all peripherals from your PC. This includes all USB devices, such as printers, hard drives, cameras, etc.
Several users reported that the issue was caused by USB speakers, but after disconnecting the device from the PC, the issue was completely resolved.

Solution 10 – Defragment your drive
If your PC is running slow, that can be because your drive is too fragmented. Fragmentation issues affect only hard drives, and if you’re using a solid state drive, you can skip this solution. Windows 10 comes with its own fragmentation tool, and you can defragment your drives by doing the following:
- Press Windows Key + S and enter defrag. Now choose Defragment and Optimize Drives.
- When Optimize Drives window opens, select the desired drive and click on Analyze.
- After scanning the drives, select the fragmented drive and click on Optimize.
- Wait while Windows defragments your drive.
- Repeat this process for all your drives.
Once the defragmentation process is finished, check if the problem is resolved. It’s worth mentioning that there are many other great third-party defragmentation tools that offer various advanced features. If you’re looking for more features, we recommend you to try Smart Defrag or O&O Defrag. Both these tools offer great features, so be sure to try them.
Solution 11 – Adjust the size of virtual memory
Virtual memory is important, and if your Windows PC is slow, the problem might be the amount of virtual memory. Windows 10 automatically manages the size of virtual memory, but you can also change it manually. To do that, follow these steps:
- Press Windows Key + S and enter advanced. Select View advanced system settings.
- System Properties window will now appear. Click the Settings button in the Performance section.
- Performance Options window will appear. Go to Advanced tab and click on Change button.
- When Virtual Memory window opens, uncheck Automatically manage paging file size for all drives. Select Custom size, and enter Initial Size and Maximum size. Now click on the Set button and OK to save changes.
After doing that, you’ll set the size of virtual memory for that drive. To fix the problem, you might have to set the manual size for all your drives. As for the size, the size of your virtual memory is related to the size of your RAM. As a general rule, the Initial size should be at least 1.5 times larger than the amount of RAM memory on your PC. As for Maximum size, it should be up to 4 times larger than the amount of RAM on your PC.
Solution 12 – Update your drivers and software
Sometimes your Windows 10 can become slow if your applications are out of date. Sometimes outdated applications can cause this problem to appear, so be sure to update them and check if that solves the problem.
Another cause for this problem might be your drivers. Outdated drivers can cause this issue to appear, so be sure to update all your drivers and check if that solves the problem.
You must know that updating your drivers is an advanced procedure. If you’re not careful you can cause permanent damage to your system by downloading and installing the wrong driver version. We strongly recommend TweakBit’s Driver Updater (approved by Microsoft and Norton) to automatically download all the outdated drivers on your PC.
