How to stop Vista from trashing your disk

Ever notice how Vista churns your HDD? I had the misfortune of having to install Vista on a machine again and finally took the time to figure out what to do to make it stop. I knew about the first four, but the last two were new to me and made all the difference:

1. Disable ReadyBoost
2. Disable SuperFetch
3. Disable the Windows Search service
4. Disable the scheduled Disk Defragmentation task
5. Disable the scheduled System Restore task (shows up as super-high System Volume Information traffic)
6. Go into the registry and disable prefetching entirely.

All these steps removes 99% of the extra disk activity and now the disk doesn't rattle all the time :)
