Performance Issues

Usually, when your PC starts showing performance issues like slowing down or freezing, you should primarily try other solutions such as deleting junk files, freeing up space on your computer, and more. Despite that, if it is still performing slowly, crashing, or freezing, reinstalling Windows 10 on your computer will fix it.

For a reliable antivirus or malware cleaner, you can take TotalAV for a try. It provides you real-time protection from viruses, malware and online threats.

Junk Files

When you download an application, the application files are stored in the "Program Files" or "Windows" folder. If you uninstall the application or delete it, the junk files are not deleted completely. These files accumulate over a period of time and eventually slow down your computer.

You can delete junk files by clicking on the start button and then searching for the %temp% folder, but still, a lot of junk files are stored across your boot drive.

By reinstalling Windows 10 again, you remove all the junk files from your PC.

Accidentally Deleting Important Windows Files

If you accidentally deleted important Windows files or a registry, your system will not function properly. By reinstalling Windows, you can recover all these files and have your PC work properly.
