I think it was going to 64 bit machines that did it, and my uneducated guess is that Win8.1Pro handles 32 bit applications better on 64 bit machines than Win7. My only other programs were on Access runtime. Maybe a Win7 installation problem on that day at the plant. Remember not wanting a car made in Detroit on a Monday? Anyway, I was desperate to get away from Win7/AC, and it worked out great for me.
The change from Windows to Mac, or between Android and iOS, is 10x larger than changing from 7 to 8.1, with the boot to desktop. I grant you that if you are new to Win8 you can feel that same helpless feeling that came from learning where Macs hide everything, but that really is just a problem for the administrator that has to set up the machines. And by the second or third machine, it is routine. Windows key and the X key together is my friend.
My employees log in like they did before, double click on an icon placed on one of their favorite pictures like they did before, and go to work like they always did. The only difference is that it turns off a different way, and that can be the same with start8 or classic shell. It's funny how I never had to show any of the employees how to put a picture of their kids or pets on their Win8.1 desktop. Metro is just this useless appendage for office based work with keyboards and mice, but it's out of the way, hidden behind the left lower corner. I would delete it if I could, but it is as harmless as an application that you no longer use, just taking up hard drive space.
If there was no price difference, I probably wouldn't have posted on this thread.
