There are several reasons I switched to a Mac from a Windows PC a few years ago. Frequent BSODs, issues with drivers, and Windows updates that ruin the experience from time to time are some of them.
Windows updates can be like dentist appointments for some people — you know they're important, but on the other hand, you're going to do everything to put them off, or get out of it altogether.
Windows Update can be a pain. Rebooting for updates is one thing — but a forced reboot for updates that shut down your running applications when you’re trying to get work done? Now, that’s obnoxious.
