.Net updates eh? I know your pains. I only install the most stable version then ignore them from 1 to 4. Some of them unmentionables just plain refuse to install on my machine. Ditto with the Office updates. Update only when it's conflicted with game/app.
And no, it's security updates. MS still churning out them little piggies quite often.
Really, when it's the choice between a stable, much tested, much beloved, possessed the biggest bloc of users and therefore internet source of feedback, it-just-wont-die-on-MS-command operating system, and a johny come lately like Windows 7, or, hah, Windows 8, I know which is my choice. Fashionable be goshdarned! When it's come to OS, functionality worth much more than being fashionable or playing the latest.
