Windows 10: Windows 10 home to pro upgrade, error 0x8000FFFF

Well, the thing is, it shows as licenced anyway - that's what's confusing me (and the upgrade assistant, I suspect)
The basic info points to a Win8 activation (albeit it obviously is Win10)

I think the OP needs to get digital entitlement via a GT.xml in order to get the upgrade - or purchase a Pro key.

 

how do I get that digital entitlement?, also keep in mind that I had been able to upgrade from windows 8.1 home to pro on an identical laptop to this one and this one was also giving a very similar error when trying to upgrade on windows 8.1.

edit: I can also roll back to the factory image on the laptop and we can try to tackle this one windows 8.1 if you think it will work better

You can get the ticket from your current install ( if it's properly activated... it reads the OEM key and HardwareID) then clean install Win10 Home with it following the instructions.

PS: If that ticket does not work, then you will need to install Win 8.1 Core first to get one.

 

okay, working on that now. will keep everyone in the loop.

 

okay, just restored my genuineticket and it's still giving me that error. back to 8.1 oem?

 

I figured what the problem is... the licencing files support Win8.0 OEM keys and thus activates with that - strangely enough no Win 8.0 retail or any type of Win 8.1 keys are included.

To bypass Win 10 using the OEM key on clean install, you have to include a pid.txt file in the sources folder of the install media.

To do this save the following in notepad as pid.txt:
[PID]
Value=TX9XD-98N7V-6WMQ6-BX7FG-H8Q99

PS: Its way past my bed-time - so gonna leave you in the capable hands of the installation experts. Good luck.

 

after following all of these instructions and rebooting 4x on a fresh install of windows 10, i'm getting connect to the internet to activate windows, Error code: 0xC004F074.

 

Sorry, I gave the wrong key.

Click change product key and enter this one:
YTMG3-N6DKC-DKB77-7M9GH-8HVX7

Then try to activate with the Genuine ticket in the correct place.

Please post a slmgr /dlv screenshot again.

 

thank you so much! that immediately activated, even after a reboot and I was then able to upgrade to windows 10 pro. one quick question: If I ever have to do a reinstall of windows 10 pro, that Ticket is saved on microsoft's server right? and would I just use the standard windows 10 pro serial number when installing?

Edit: I just kept hitting skip and do it later and it activated automatically when it got online. That was pretty neat.

 

Excellent!.. thanx for reporting back.

Yep, your PC now has been registered at MS with Win10 Pro digital entitlement, which means you can re-install Win 10 at anytime and skip entering a key as it will be activated with the already registered entitlement.
