that is because antipiracy technologies not run at the moment, but when microsoft put online,and you can dowload active x, pass validation and receive new win updates, may be other troubles with loaders come.
troubles with loaders will come once WAT is released with SP1.. we talked about this many times.If you dont have any problem right now, no problem.. continue using your O.S... once you have problems, you should do bios mod and get genuine W7 again
