Hi, I'm running Windows 10 Enterprise on build 1607 (14393.0). I was having problems installing Windows cumulative and security updates, even just one at a time as a standalone update. After the restart, it would get up to 98 or 99% and then I would get an error saying "couldn't complete the update, undoing changes..." . I tried solutions I found on the internet (Windows update troubleshooter, the ResetWU tool...) Nothing worked.
Exasperated, I turned to Tweaking.com Windows repair v3.9.35. I did all the optional verification first. Aside from finding a few re parse points, everything checked out, including the file scans. I then went ahead with repairs. I backed up my registry and made a restore point.
I then tried to only perform the repair windows update option (#17). It did not fix the problem. I proceeded to run repairs 1 through 32 (excluding 11, 12, 13, 16, 18, 20, 22, 24, 25, 31, as I didn't feel it was necessary). After I rebooted the system, the windows apps were greyed out. I ran a system restore and got back to where I was. I figured maybe I should disable my anti-virus and repair in safe mode. So I did but it made no difference. I went to restore the system only to discover that my restore points were gone, so I could no longer restore the system.
I tried the repairs again (in safe mode). Problem still there. All Windows apps are greyed out, including the Store. I then tried to only run 28.01 and also 28.02.The problem remains. I get red messages that say the path to AppxManifest.xml is invalid and to check that resources.pri exists. But I checked the path and it is valid.
At this point I was discouraged and decided to perform a in-place windows repair install using my Windows enterprise image on a USB key. Well, I can't even do that anymore apparently. When I run the Windows setup, I get an error saying "Setup couldn't start properly. Please reboot your PC and try running Windows 10 Setup again." I tested the usb key on my other computer running the same Windows build and it launches fine.
So now I'm about out of ideas. I don't want to have to re-install Windows 10. I just have too many programs to re-install. I do have a per-repair Registry backup but I'm afraid to use it. Interestingly, I also found that I could run the Windows 10 Creator update setup fine. But I'm afraid to do that as I read that Microsoft does not recommend installing the creator update upgrade from an image and to wait for it to be dispatched through regular windows updates, which I can't do to begin with. In any case, the Enterprise version doesn't upgrade that way anyway.
Any help that could help me fix this mess would be greatly appreciated.
Thanks.
