Used Windows Update just now and had no problem. The people with this problem are probably either having network that is incompatible with Windows Update or did something with Windows’s settings.
Last week, because of a thread on FR, I checked for updates and had a few pending so I processed them. Man, you’d think I was installing W10. It took forever and required several restarts.
Them I came to the computer this morning and damned if there wasn’t more updates to do. No problems other than time spent, though.
