On Windows 7 Pro, it appears to be update KB3035583 that is the problem.

Thanks,
deinstalled that update and everything works fine again!

I read up on that upgrade program. It is available July 29 and will be ready to run on that date. It also said that the required files would be placed on your computer before that time so it's ready for the 29th. No idea how much space I need to reserve or when things will be installed.

3GB is the official MS Werd.

Thanks Ed.

OK, I uninstalled the bugger (KB3035583) and hid that update so hopefully it won't install again. I keep my music rig offline most of the time, and really could probably run Windows 7 Pro for the rest of my life without any more updates. just install new software from an external drive after downloading from my other computer.
 
Incidentally, I checked on my other computer, which is a triple booter, and the thing did install on one of my W7 Home Premium drives. It's the same update (see above). That one I will probably fool around with to see if W10 is going to be worth it. I use the Vista drive most of the time, however. Fully updated Vista with SP2 is in my opinion Micro's best OS. but then, I'm kind of a retro-type guy....
