Hello, Having a bit of trouble with this one.... Basically my dads XP Pro retail OS PC is plagued by the WPA message and running slow with internet explorer and needs sorting out. I've downloaded the OEM tool kit, which created the necessary folders, ran the boot disk tool to get the CRC (NEC CRC=678752DC), downloaded the correct file set and unzipped into "uncompressed" folder. First thing I noticed is in the sticky it says run the OEM.exe but found this wasn't found anywhere in the OEMbios changer folder but found OEM.CMD, so ran this but it's window quickly closes, I can just get time to see an error about a registry key not found or something. Any help to get this sorted? Ty.
