    Rollback install from windows.old or help with EFS file recovery


    Yesterday, my Windows 10 installation became completely unstable. After trying a few methods to fix it, I decided to just reinstall from scratch. Windows and Office are both reinstalled and working correctly now, however, I had used the Advanced Attributes in File Explorer to 'Encrypt contents to secure data' of one folder. Now, all of the files in this folder are inaccessible.

    Is there a way I can roll back to the bad version of Windows10 to extract these files? Alternatively, can I somehow use the user information in windows.old to access/unlock these files?

    :)

    Windows.old Folder will automatically delete after about thirty days since installation. If you wish to remove it earlier than the 30 days you need to use the Disk Cleanup program.

    You only need it if you wish to return to the older operating system.

    Most new machines come with a recovery partition allowing you to go back to the time of purchase, you will have to check your user guides (or the manufacturer's Web Site) for instructions. Choosing that path requires you to save all valuable data first.

    On the Windows.old. This is where Windows stores the files from the previous Windows build. This may or may not be your Windows 8.1 depending on if you installed more than one Insider build.

    If you go into Windows.old and look at the date on the Windows folder, you can get an idea of that was about when you installed the Insider build, which would mean that it is Windows 8.1.

    To try to rollback select:

    Settings -> Update & security -> Recovery -> Go back to Earlier build

    If that doesn't work I really don't know any other procedure.

    If you are encrypting files. Not decrypting them before a refresh will not allow you into them.
