I'm getting annoyed with Win8
On two machines it insisted on rebooting to "install updates" despite my checking the "later" box -- and then went into a death spiral. Half an hour later it corrected itself, said the "update failed."
I was thinking I would have to re-install Win-7, it all happened without any warning and then the screen just went blank. Fortunately I have some experience with windows -- I just walked away and left it running, and eventually it came back.
I honestly don't see any advantage on a laptop or a desktop -- I don't use any of the "aps" and the programs are harder to get to and sometimes don't work.
AC works fine, fortunately; as does Medware.
