Just reinstall, activation is taken care of via BIOS(No COA) or use purchased clé si vous upgraded.
Can anyone confirm/deny the validity duse methods or make suggestions on comment better accomplish activation après a reinstall? Je suis mainly concerned avec XP depuis the information J’ai found is rather scattered and Je sun’est pas sure if its possible to activate a “royalty free OEM” using a generic OEM/retail disk installer and Windows Key Mise à jour Tool or si je would need to use one du old methods of backing up the fichiers and altering the installer disk.
If il y a any known problems with activation on any version using the windows images/techniques I listed can quelqu’a veuillez elaborate on lem. Je suis asking because I started a new job that requires re-l’installation every version of windows on various ordinateurs that have OEM and retail versions.
The information I gathered on various forums is rather scattered and contradicting, c’est why Je suis posting this seemingly stupid question that vous pouvez think a été answered a million times. I want quelqu’un to give me a definitive response so I ne screw someones ordinateur up by supprimer necessary OEM fichiers.
