Reasons Why You Might Need to Reinstall Windows

There are many instances where you will need to reinstall Windows on your computer. If you already did not know, Windows corrupts a lot, and the only solution can sometimes be to reinstall Windows altogether.

There are even more instances, where reinstalling Windows helps, such as:

  • Junk
  • Malware
  • OS Crash
  • System Failure 
  • Virus Infection
  • Performance Issues
  • Accidentally Deleting Important Files

Let us look at each one of them briefly.

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.

Malware

If your computer was infected with malware, a virus, or adware, reinstalling Windows on your PC wipes it off your computer.

This is another reason why you should consider reinstalling Windows 10 on your PC.

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.
