Got a Panasonic Laptop CF-37, it had Win 2000 Professional on it...they put XP over that copy...now it is requesting it to be registered and it can't be due to the fact it is already registered to a different computer...want to uninstall this and put on Win 98, but the XP is not located in Add/Remove Programs...was going to fdisk, but cant do it that either...can someone help me with instructions please...
