Install Windows 8.1 SL RTM on a Windows 8 Laptop
I recently reformatted my Windows 8 laptop to Windows 8.1 and I had a few issues with the serial number. So I researched all morning and found some stuff. And decided to post it here.
- You need the Windows 8.1 SL RTM disk image. You can get them at any torrent website.
- You need to extract your Windows 8 serial number from the BIOS using a tool like
Key Finder from MagicJellyBean and write it down somewhere.
- Boot into the Windows 8.1 disk, and when it asks you for a serial number. Use this generic key: Y9NXP-XT8MV-PT9TG-97CT3-9D6TC (This key is for the Core version and not Pro nor Enterprise)
- After you install Windows 8.1, right clock on the start button and open Command Prompt as admin, and type this: "slmgr.vbs /upk"
- Then this: "slmgr.vbs /ipk
your-key-here"
- Then simply right click on "This PC" and activate it, and you're done.
Cheers people! :)
