I have an ASUS modded bios (SLIC OEM) and my Win7 ulti upgrade to Win10 was no problem and its activated. Question is: can I now upgrade my bios and lose the OEM key without any windows 10 issues? The bios I'm using now is over a year old and a new bios update would fix some issues on my motherboard.
Hi Nytigrnla, I upgraded a slic activated windows 7 to windows 10 and then checked it was activated. I then loaded a non slic bios. its is still activated. so you should be safe enough to upgrade your bios. I am not sure what happens after a clean install (boot from cd) though as I don't have a unique product key do you have to have a Microsoft account to get a unique product key? or is there another way? I had hoped to do a fresh install onto a new larger disk but I don't know how without a product key.
Updating your BIOS/UEFI shouldn't effect the Hardware ID that was used for Activation of Windows 10. If the Hardware ID of your PC stays the same, then you'll stay Activated and can do a clean install that will activate once inside the OS.
I have reflashed my bios slic modded with original after win7 --> windows 10 update and reistall it clean without cdkey and successfully activated
