When I started on this 'adventure,' the issue was that a windows update left my one year old computer at 'Please Wait.' After I was able to boot into safe mode, I was adjusting the services starting with the boot into windows. Then the Taskhost error and task bar problems cropped up. I never got past that. Did both problems have the same root?
I tried booting with no external devices and all my external devices, and stuff in between.
I tried restore points, scannow and DISM. All to no avail.
Microsoft support worked on it with me.
I have the same hardware I had before my clean build, but clearly I don't have all of the software I had before.
Bad Code? Maybe. Random incompatibility? Likely.
Just an aside, most of the same software runs on my 9 year old, 32 bit dell laptop. It started out on Vista, and was upgraded to Windows 7 and Windows 10. It had no problem with this update.
My 1 year old Acer 64 bit desktop with a current I5 processer was born on Windows 10 Home, ehhhhhh.....
