Upgrading to a new or same version of Windows Microsoft create a folder called Windows.old in c drive which helps us to revert back to the previous version of Windows if any disappointment to the newer version.
I am seeing this as a backup option, I have never used this feature though but thinking what if I copy the Windows.old to the another drive and kept it to my satisfactory till I am fully satisfied with the new version.
I am not follow this practice for all the PCs in my environment though but we have some critical PC which got broke last time while upgrading from Windows 10 version 1703 to Windows 10 version 1903.
If I move Windows.old folder to another drive or partition and move back again to the same place in the PC will this helpful? will Windows detect the folder again?
