Salutations I would like to know how to install and mostly how to activate Win 7 without a loader. I've read some articles, and it seems, from what I've understand that you need 3 things: an OEM certificate, an OEM Key and a product key . I'm not sure if i am right or not !(i admit; i got a little scared about what could happen if I do something wrong, as it's about the OS ) So i would like to know the "how to" explanation, as i prefer to control and know a minimum what i do instead of using a program (i know adout Daz's Windows loader), and learn something along the way. Also, I've deleted slui.exe, as it was nagging me about my inactivated copy. I am now concerned, would that compromise the activation process ? Ps: Windows was pre-installed on my Dell laptop (vostro 1015) but not activated, i used the rearm method, the messages about activation stopped and I was able to use my laptop normally (windows updates, Defender updates, etc), and suddenly went "inactivated" again. I suspect a hardware - the HD probably- problem, as navigating/accessing/reading folders and files was slow, and "stuttering" occurred when listening to music (locally), so i did a volume verification, but i don't recall it performed some bad sector recovery, or fix sectors . Thanks in advance.
