The old Windows installation will be moved into the “Windows.old” folder, and a new “Windows” folder will be created. So, will a clean install of Windows 10 delete your files?Ī fresh, clean Windows 10 install will not delete user data files, but all applications need to be reinstalled on the computer after the OS upgrade. At the same time, I don’t want to lose my data.

Sometimes I need to reinstall because Windows is getting crashed and sometimes when I want to clean malware (clean install does not guarantee to remove viruses, however). When I keep installing new applications on my machine, they often run processes on the background and slow down Windows. Reasons to do a clean install are various. Now locate the ProgramFilesDir registry value and make sure the corresponding value is C: \ Program Files, where C is the drive you previously installed Windows on.Every so often I need to reinstall Windows on my PC.HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion.Press Win + R and type regedit to open Registry Editor. These registry values can result in an unsupported directory error. If they are changed, it may interfere with the update or new installation. There are certain values in the registry. Otherwise, you have no choice but to manually back up this folder and perform a clean install. Find the folder and put it back in place. Without this folder in the right place, Windows cannot clean up the installation, because before a new installation it is necessary to back up the lost files. However, you can accidentally move your “user” folder that corresponds to your account. This is the default setting for all Windows installations. On your computer, there is a user folder under drive C, namely “C: \ Users \”. Also use the official Windows installation media tool to complete the installation. You can see most of the information about your computer by right-clicking the This PC icon and choosing Properties. Make sure the installation media and the current version are in the same Windows variant category. The problem can also occur if you are using 32-bit installation media on 64-bit Windows or vice versa.

Also check if your Windows is monolingual or not. For example, you can’t use the Windows 10 Professional installation media to properly install Windows 10 Home.
