Create another user account that is an administrator account, password
protect it and make SURE you document the password for your use. Then change
his user account to not be an administrator. Of course beware this may upset
him as he can not do some of the things he wants but you will have to deal
with that and moderate that.
You may want to install Logmein on his computer so that you can access it
remotely to do repairs/adjustements as that may make life easier for you.
There is a free version available. I use that to help my Uncle remotely. A
HUGE advantage of Logmein is that it works through firewalls and does not
require either end to have static public IP.

Otherwise your options may be to use System Restore to undo changes he has
made and/or use an image backup program such as Norton Ghost or Acronis to
have images of the whole computer backed up regularly to an external hard
drive and then just restore the image if problems arise remebering to backup
up any data files created after the last image backup first.
