Despite using Mac OS X for most of my daily work, I normally have one or two Windows 7 virtual machines running in VMware Fusion. But Windows Automatic Update is causing me trouble. It automatically restarts these virtual machines whenever there is an OS update, which seems to be every night lately. This automatic reboot kills whatever programs happen to be running at the time, causing me to lose half-written articles (even though I saved them and Auto Save is on) and almost killing an old BlackBerry I was updating. I had to figure out a way to disable this automatic reboot!
