My mother has an old Vista machine (it does for what she needs: E-mail, bank, reading the news paper and Facebook). It downloaded a update yesterday morning. The usual bullshit--upgrades to IE, security patches--no biggie.
When it rebooted: It did a complete reinstall of Vista and wiped all the prior upgrades. No boot disc in the the DVD drive, no USB keys attached, it just reinstalled Vista back to factory from itself and wiped everything like a new install. We had the devil's own time getting the software key to accept (the one of the back of the case that is the Windows Vista software key).
Never had a computer stroke out and self reinstall. No clue how it did it or why the last update caused it.
