I am using win XP on my laptop. It has Win XP home license. I don't like XP Home so I installed XP professional on it and it had the Eth0 reset 5.02 pre applied. I further applied the Wpatcher crack on it in order to install the apps that require WGA. Now I have got a legit key for XP but how do I apply it and activate the windows as the WPA is not available? Please help me solve this problem. I don't want to re install windows.
