Windows 7 Home Premium is presently doing an upgrade and 8 of 11 is taking 5 hours so far, on a fast laptop (intel i7, 64 bit) and high speed internet. The upgrade started when I tried to shutdown the computer. The machine had been previously operating 8 hours per day for the last week. My questions: 1) Can this be something other than a legitimate upgrade? Or is Microsoft really issuing something massive this weekend? 2) The upgrade seizes control of the machine. Is there a way to take back control?
