i have read your artical,, ”How can I change the volume licensing product key on a Windows XP SP1-Based Computer?”
and followed it,, till the step 10. but,,, instead of accepting the new key,, it says an error message ( with disabling me from entering serial key) ” only numbers are to be entered, .”.. it means,, microsoft have disabled the key change.. and only numbers ( no alphabets ) can be entered this time,,. so what should i do. can you find the solution of this thing..
i have windows xp professional version 2002
