    Enable/Add Data Dedup to Windows 10?


    Hey all,

    I went ahead with the Windows 10 Upgrade to my main PC. I have a secondary drive (E which holds all my music, games, etc; stuff that I like to keep away from a Windows Install. In Windows 8.1 I had the Windows Deduplication enabled on the whole drive. Now, I cannot access any files whatsoever on that drive. Since it's something that constantly works in the background, I forgot about it until I really needed it.

    My Question: Is there a way to enable or add Windows Deduplication into Windows 10 yet? The only info I found was from this article (in 2014):

    mcakins.com/2014/10/10/enabling-deduplication-on-windows-10-tp/

    It's for the Technical Preview. I followed the steps anyway, and I get an error while trying to add the packages:

    Error: 0x800f081e
    The specified package is not applicable to this image.

    If it is not possible, is there a way I can revert and undo the Upgrade and go back to my Windows 8.1 setup? Or do I have to wipe the drive and clean install?

    Thanks,

    Llama

    Never found an answer, so here's what I ended up doing:

    I reverted back to 8.1 (using Settings -> Update & Security -> Recovery tab) and then I ran the Unoptimization job type in Dedup on the volume (E:). This took about 16 hours to restore 350GB and a restart to get everything back to their full file sizes (time will depend on your own storage/file sizes).

    Once that was finished, I did a clean install of Windows 10. All files are accessible.
