my old Toshiba lap top runs Windows 7 home premium. The other day, it did an update. I shut the machine off, and drove with it back to my other home in North Fl. When I turned it on, it started doing the 'configuring' stuff thing. It ran for hours, saying it was 100% finished. I turned it off, back on, and now it said 35% finished. Another hour or so, and I turned it off again. This time, when it started, it said 'cleaning up'. That ran for another hour, and then, voila, it returned to normal.
I really hate Bill Gates. One of these days, it just won't restart.
There are two external hard drives that I back up on. All my doc files, pictures and things. If it dies, it dies. I won't really lose anything but time and effort.
