Dear MDL! 1, Is there a permanent BIOS/UEFI mod based activation for Win10 just like we had for Windows7 back in the days? 2, Is it stable are there any drawbacks? 3, My fresh and first Win10 home PC installation is watermarked and I am inclined to use the KMS based periodic registration to get rid of the watermark. If I use the KMS based periodic registration (I have installed the Win 10 x64 Education N) can I later switch to an UEFI mod based permanent activation? +1, Is there an existing Q/A thread I can post these trivial questions so do forums dont need to be littered? BR! J.
