Annoyed by Windows Vista constast disk activity? If you have a desktop you may not even notice, but in a laptop it is utterly annoying. To me, turning off "shadow copies" resolved my problem. Right click on computer, properties, go to the system protection tab (wait a few seconds) and uncheck your hard drives. Read the help file if you need more info on "shadow copies" which is basically a small version control system that, in my case, was not needed. Why is it "on" by default... well, because is a feature right? they had to turn it on otherwise who would use it? ;)
A brainstorming blog of whatever comes into my mind and, somehow, I feel relevant to share :)
