hi, I tried the Windows7 Loader1.6c by hazar , but had a few issue, is there another loeader I can try? I do not want to consider moding bios at this stage, but maybe I am doing something wrong I could appretiate some advice. windows7 loader1.6 seems to work fine for windows 7 64-bit and 32-bit non-brand machines I used at home or work, but on a toshiba system that belongs for a friend of mine, I installed windows 7 on a separate partition and tried this , after reboot it was activated. I then rebooted and it said it's permantly activated. so next, I booted into vista to see what happened, and vista went into grace perdiod. so I decided to try the loader on vista as well, after rebooting , it said vista was permanently activated. I rebooted a few times to both OS, and no strange messages, so I left his house. then after a few days my friend calls and says window's vista is saying it's not genuine on the logon screen randolmy and sometimes in other places, but mostly on startup. so I came by and checked everything but the non-genuine message did not come up, I re-installed the loader on vista, then on windows 7 and then rebooted a number of times between the 2 OS and everything seems to be normal so I am confused. so I told him to call me if the message comes up, and it did come up again, from vista he says. so now can I need to understand what is causing this, did I do somethnig wrong? thanks for any help!
