How many times can you reinstall Windows?

6 reasons Why You Might Need To Reinstall Windows.

1. Performance issues

Your computer is slow and freezes regularly. You have tried other techniques, and nothing seems to be working.

2. Malware

Malware is malicious software within your computer system. Viruses, spyware, and adware are among the most common forms of malware.

If you have relentless pop-ups and hard-to-close tabs appearing regularly and seemingly from nowhere, then it is time to clear the decks of the malware in your operating system.

3. Junk

Your computer has built up a lot of junk files and is slowing down your system. You need to remove these files and there is too much for you to do it manually.

4. Upgrading your Windows system

You are looking to upgrade your Windows system to the newer version. It is much better to install the version of Windows you wish to use as if brand-new, instead of upgrading the system.

This will ensure all bugs, malware, and junk files are removed from your system before starting with the new version.

5. Accidentally deleting important files

All laptops and computers possess important files that are significant to the way their systems function. If you have accidentally deleted these and need them back, then reinstalling Windows will do this.

6. Corrupted registry

Your computer runs every operation and program using a database of codes. Sometimes, these codes can corrupt. This can be because of installing faulty programs or because of malware.

If this happens, then your Windows system will not operate as it should. Reinstalling the software will fix this.


Always be sure to follow any steps on your device when reinstalling Windows. Continue to look after your devices and keep the malware at bay.

Back up any files that you do not want to lose before reinstalling Windows, and ensure your computer or laptop is connected with enough power to see it through the process.
