    Right on!!

  • John says:

    Wow, works like a charm! Thanks!

  • Nikki says:

    You are an absolute star.

    I work in a school and needed to sysprep a new laptop before i could image it. It was originally a home edition windows 8 and I upgraded (using our site licence) to 8.1 pro edition. Your regedit commands worked a treat and now i can carry on with the job in hand. Thank you for posting this answer. I’m sure others will find it just as informative as I have.

  • Reed says:

    Thank you very much for finding a solution to something that should never have been a problem! None of the Microsoft related sites offered a working solution. I’m fortunate to have stumbled across yours.

  • Robert says:

    FYI- I did find another possible cause of this error. If the drive is bitlocked this error will result. Decrypt the drive to proceed.

  • stevenuwm says:

    Works for me! In addition I had to re-arm Sysprep. Also, I did not need reset the CleanupState. Thanks!

    • Harry Caskey says:

      Awesome! I’m glad you were able to get this to work! I reset the CleanupState as a precaution, but it may not be necessary. I’m glad it worked out for you!

    Appears to also work on Windows 10.

  • Sapan Manjhi says:

    Tried the same registry trick but not able to do sysprep, its giving the same error. Upgraded Windows 8.1 to Windows 10 Technical preview

  • Alex says:

    I’m trying to use this fix because I want to move the user folders from my SSD to my 1 TB hard drive. I get the error, but once I go into to the setupact.log, I can’t find any of those things in the registry. I need to get this figured out soon because my SSD only has 4 GB left. Please help

    • Harry Caskey says:

      What is the error message you get?

    • trlkly says:

      There’s another way I could see to do that if it’s just the User folders. Boot some other OS that can read NTFS (like a live Ubuntu CD), and then copy the User folder to the other drive. Rename the old Users folder (just in case), and then create a Symlink or Junction Point to the Users folder on the other drive.

      Though, personally, I wouldn’t move the entire Users folders. Those are used a lot, so you want them on the faster drive. What needs to be moved are all your Documents/Images/Videos, etc. You can do basically the same thing I described above, except you can actually do that from within Windows.

      In fact, I’m not entirely sure why you would try moving the entire OS to the slower drive.

  • Micah says:

    first…thanks!

    I just did this on a Windows 7 Pro Upgrade to Windows 10 Pro.

    success!

  • Kris Dages says:

    For anyone saying this doesn’t work, make sure you check the ** System32\Sysprep\Panther\setupact.log ** file and see what other errors you might be getting. Turns out I had to uninstall any apps I had installed from the Windows Store. It’s unfortunate, but Microsoft requires any Modern UI apps to be sideloaded instead of automatically updated. :(

  • Jamie says:

    Also works on Windows 10 RTM to Windows 10 Version 1511. This saved me from a lot of cursing Microsoft. After all, I didn’t want to rebuild my entire gold image from scratch every couple of months because of their new service model. Thanks!

    Perfect!!

  • Ben Yessayian says:

    I had some message saying I had to uninstall a Microsoft_SurfaceHub thing. This helped remove it. Then it worked!

  • Excellent post!
    Works like a charm after hours and hours of searching on the Internet.
    Thank you!

  • Mark says:

    Perfect!!! I love You!!!

  • Mike Jones says:

    I Strongly recommend this be done as Administrator. Remove all of the other accounts since apps are auto installed for them. This is the only way I got it to work.

  • Sam says:

    Thanks, it worked perfectly for my upgraded 8 to 8.1 Windows
