hi everyone, this is my first post. so my friend recently let me use his W7 RTM OEM and i installed it. afterwards, i used the windows1.8 toolkit to activate it. i thought i was done, but when restarted, the "need to activate" message appears again. i spent a good amount of time reading this forum for the first time. ive learned that i could flash a modded bios to make the activation permanent. however, i want to do as much research as possible before i make any mistakes. i want to know that if i flash a modded bios, will i have to reinstall W7? and if i flash the bios, do i use windows1.8 toolkit or something else? thank you for everyones help.
