I have 90 processes running when I go into task manager. This seems to be slowing my computer down. ...
garmanma gave good advice. Here's another resource:Vista Services Explained
Also it may seen a bit laborious but it might be a good idea to create a text file to log all the changes you make. Maybe something in Documents folder so you can find it easily. Make one change at a time and if things go south then it's usually the last thing you changed. You can look in your log and see what the previous state was and how you altered it to back it off and reboot. Also the more Restore Points and system snapshots you have to back you up the better. Esp. Vista is a lot trickier than XP so getting by with just Restore Points is counting on luck. Better to shell out $50 for a good image backup software and get an external drive to save your system state. If it won't boot, you can boot the image restore CD that should come with your system snapshot program and restore from the backup. The kind you want is the type that saves all your programs and restores your PC to the state it was in when you made the backup. IOW, you don't have to reinstall all your programs like you do when you do an ordinary system reinstall.
I've been using Paragon Drive Backup Personal edition myself but there are a few reliable system backup utilities out there that you should be able to buy for $50 or less.
Google around, go to the support forum for each product and see which has the fewest customers left hanging with unusable systems!! Also try to look for people with hardware setups as close as possible to what you have. If it works great on their machines the chances are much better it won't break yours.
