Microsoft set out to create an easier upgrading experience with Windows 10 when compared with earlier versions of Windows OS. Those who just wanted to upgrade over the Windows 7 or Windows 8.1 generally managed to do so without too many concerns. The people who did find faults had 30 days to find specific solutions or choose to downgrade the OS back to where they came from.

Downgrading should always be the last trick to try and not the first. However, some errors do not allow for any fixes apart from reinstalling so it’s important to understand when you must cut your losses.

The guide below will teach you how to reinstall Windows after deleting some of the problematic files.


  • Make sure you check the box for hidden items when browsing files and folders.
