Activate it by phone.
Write down the registration code XP gives you, then go to your phone and call Microsoft\'s activation line. You will punch in by keypad your registration code. Then Microsoft will give you the activation code in six number groupings. Write down the activation code as Microsoft gives it to you. Hang up the phone. Go to your computer and punch in the activation code.
Fairly painless, it\'s all automated--you speak to no one. Just make sure that when you are on the phone, family members or roommates, etc., do not distract you.
When you are done. You now have both registration and activation keys so if you need to reinstall, you check your written registration key against the one XP is giving you; if it is the same then your activation key will work. If not, go get another from M$.
The only information M$ could possibly get from you in this exchange is your phone number so use a friend\'s phone, payphone, etc. if you are that paranoid.
cheers.
