Hi, I'm apologising already fo this so don't go ape on me!
I read somewhere that Windows Xp doesn't like it when you change significant parts of your hardwear and asks you to put in your original XP disc to verify that it is still a legit person using its softwear and not some copy or whatever.
So if, hypotheticaly speaking, you were to use someone elses copy of Windows Xp Home and then use a keychanger to allow you to validate it (and get all the updates etc) and then at a later date changed loads of your hardwear (such as your moboard) wouldn't it just laugh and tell you to fuck off when you tried to use that original Windows XP disc or a back up of it, cos the key code is diffent????
I have read loads of posts and tutorials, but this wasn't explained in any I saw!
