personaly, I like to keep a folder on my c drive labled I386. As long as there is enough HDD room. Then, I'll load up everything from the latest install version...ie SP2 to it. After which, a quick registry change and instead of needing the install disk everytime you update, upgrade replace a componant or software program...it'll just look there instead. I recommend doing this on any PC you make for a less knowlegible friend.
