cracking xp

I have just tried to load xp onto my computer (having moved) and can't find the damn reg keys that I had.

I have therefore used a key generator to make some keys, I tried 11 of them and they don't work.

Do I have to generate the keys on the PC that I am using the key on or am I missing something else?

Some keys are only for WinXP, some are only for SP1, some are only for SP2, etc. Make sure you're using the right key for the version you've got.

...but stealing is wrong. So why steal when you can
