Hi, i am a Windows 7 user. Actually i have installed Windows 7 RC Build 7100 last year somewhere in May. Now, i guess its expiration is near, and if i am not wrong it is in May or June 2010, right ? Actually, from last couple of days, my system is behaving in some strange manner, like it is taking much time for startup, reboots sometimes automatically, etc. So i wanted to know the Expiry symptoms of Windows 7 RC ? Please help me out. Help appreciated.
