Installed the leaked version of 8.1, I have a legit windows 8 pro key, but it says I can't use it with this version of 8.1 ... Anyone know if you need a certain type of windows 8 key for it to activate?
From within Windows 8.1
Created a new folder
c:\wmc
within this folder i created a further folder called "MOUNT"
copied the install.wim file into the c:\wmc folder
I then mounted the original windows 8.1 iso
To f: (virtual dvd drive)
Then i Opened a command prompt (admin)
copied and paste this command to mount the image:
DISM /Mount-Wim /WimFile:c:\WMC\install.wim /index:1 /MountDir:c:\WMC\mount
Copied and paste this command to enable netframework 3.5:
Dism /image:c:\wmc\mount /Enable-Feature /FeatureName:NetFx3 /All /Source:f:\sources\sxs /LimitAccess
Copied and paste this command to enable Windows Media Centre:
Dism /Image:c:\wmc\mount /Get-TargetEditions
Dism /Image:c:\wmc\mount /Set-Edition

Manually copied my tokens.dat & data.dat files to: (I copy both tokens.dat and data.dat from my activated copy of windows 8 pro retail key & media center key last year)
c:\WMC\mount\Windows\System32\spp\store\2.0
copy and paste this command to injecy my WMC key:
Dism /image:c:\wmc\mount /set-productkey:*****-*****-*****-*****-*****
nb *** replace with your key.
Copy and Paste this command to commit the changes made:
Dism /unmount-wim /mountdir:c:\wmc\mount /commit
I then changed directory to rename the image:
c:
cd wmc
imagex.exe /flags "ProfessionalWMC" /info c:\WMC\install.wim 1 "Windows 8.1 Pro with Media Center" "Windows 8.1 Pro with Media Center"
Open up windows 8.1 pro with media center iso with ultral iso and go to sources and copy or drag the file "EI.CFG" (you will find it
from windows 7 on my digital life forum) and save it. Burn ISO to USB stick (you need at least 4GB) I use 8GB stick.
Finally, (make sure u disconnection everything wifi, ethernet as u don't need it until installed is completed.
installing windows 8 on your pc, choose windows 8.1 pro with media center and click next to accept agreement terms,
it will continue installing on your pc and windows will be let's start to desktop. Check system information. It activated!
It won't ask you for any product key. You now have a fresh copy of Windows 8.1 pro with media center on your pc that it already activated.
No need to phone Microsoft or online to activated. It including working Net Framework 3.5 as well.
Enjoy it.
For EI.CFG (open up with notepad and make sure it had the correct line below or otherwise it won't work):
