They always do this when a new Microsoft OS comes out . I think most of the complainers are from other OS companies , like Apple and so on . Windows 8 is going to be the next big one within time . I like it and i have a pc with xp , 3 laptops >>> Linux Kubuntu , Windows 7 U 64 and now Windows 8...
I think I read somewhere its there way to fight illegal OS software from being installed . Were you can't use the same oem keys over and over again . this way now it gets tied to the one system alone . Which will stop illegal OS from being install .. I could be wrong but I think that's why.
Are you using a 64 bit Windows version ? Because unlocker has a 64bit . Once you install it reboot your system afterward locate a file or folder you want to try it on it should show once you right click the folder
oh ok . I thought you knew something other wise , why I asked ... In your problem with the bios I would keep trying the f2 key . Its retarded if you can't get into the bios
If your on your desktop screen . Place the mouse at the bottom right of the screen click setting and then the power. You will have the options to shut down, restart or sleep. It seem pretty simple
