Hello you honourable knowledgeable people, A Quick Question If XP Home on the PC is not a genuine version, can I load a genuine version without having to delete the non genuine version. If so what problems would I encounter??? If any and how would it affect my PC?.
If you try to install the legit copy over the pirated copy, you may well have problems. See HERE.
After backing up your impotant data, use a hard disk utility to zero fill the hard drive, including the boot sector. Then format the drive in the NTFS file system and install the new copy of Windows. You should then be good to go.
You wouldn't need to reinstall. You can simply replace the currently used XP key with the proper one that you have bought. Once that's done, if you install the Microsoft Advantage software, it should notice the legit key & give you access to all the udates (critical & optional).
Very Many Thanks to you both it is a priviledge to know there are people with the knowledge to help those of us who struggle. It seems that 2 of us have learn't something. Please keep up the good work from a very very grateful Novice.
