Updated 2 of my computers. One of them worked fine...the other one, when I turn on is blue screen only. Probably have to take it in.....
Just for laughs, decided to let it try to update overnight. Went to bed at 11:00 PM still had the gray screen with the spinning dots. Got up at 5:30 AM today and still had the gray screen with spinning dots.
In disgust I held down the power button then powered back up. Looked like it was going to power up normally then I got the message "attempting to recover installation".
Blue screen comes up then "86% don't turn off your PC- your PC will restart several times".
Twenty minutes later It gets to 100% and reboots. Looks normal, then to a nice pulsing "Hillary shade of blue" screen with a greeting "Hi" and telling me my PC has been updated, getting everything ready, blah, blah blah....
Finally got to my desktop. Email works and Firefox browser works. Now checking everything else. Not sure why it hung up like that all day yesterday and all night but powering off and then on again cured it and apparently the update was successful (for now).
Thanks for all the suggestions.
