Hi, thank you for that information. In this case, I suggest doing an in-place upgrade, wherein it will upgrade the device to the latest version and repair all issues without deleting any files.
Note: before doing this, make sure to create a restore point: https://support.microsoft.com/en-hk/help/4027538/windows-create-a-system-restore-point
