When I try to upgrade my windows 10 pc from Windows Home to Windows Pro (using my own MSDN key), it says 'We couldn't complete the upgrade, undoing changes'. I cannot find the problem and this problem has been here for almost a complete year.
I'm getting the following erros in eventlog:
Installation of the Proof of Purchase failed. 0xC004F069
License Activation (slui.exe) failed with the following error code:
Package Windows Professional Edition failed to be changed to the Installed state. Status: 0x800f0922.
this isn't a clean installation and I don't want to perform one.
Please see the following thread for more information:
default troubleshooting steps like diagnostic/clean startup, dism, sfc /scannow aren't working. (see thread above for troubleshooting steps I've taken, I've made a new thread cause these are other errors but the same problem)
