Looking for solid confirmation on how Windows(XP,Vista,7,8) OEM can be reinstalled/activated
**Windows XP (Home/Professional) OEM(SLP) (Dell, HP etc.)**
Using
- GRTMHOEM_EN.iso (Generic Home OEM)
- en_windows_xp_home_with_service_pack_3_x86_cd_x14-92413.iso
- GRTMPOEM_EN.iso (Generic Professional OEM)
- en_windows_xp_professional_with_service_pack_3_x86_cd_x14-80428.iso
Installer using any media that matches version, use [Windows Key Update Tool](http://windows.microsoft.com/en-US/windows/help/genuine/product-key?siteID=rGMTN56tf_w-veEVLcikq2nT0uajvMMRqA) to activate it as Retail or OEM based on clé provided. (True/False)?

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 problèmes avec activation on any version using the windows images/techniques I listed can quelqu'un veuillez elaborate sur lem. Je suis asking parce que I started a nouveau 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.
Windows (ALL) OEM activation
Re: Windows (ALL) OEM activation
**XP**
To installer on "royalty free OEM" machines (HP, DELL, etc.) vous pouvez get the vendor's oembios fichiers from [the oembios repository](http://www.oembios.net/), or backed up depuis le current installation.
You ensuite need to use the SLP (système locked preinstallation) clé that corresponds vers le installation media's product ID. These used to be archived sur le My Digital Life forums, but were [taken down due to DMCA request](http://forums.mydigitallife.info/threads/15438-XP-SLP-keys-removed-from-MDL-due-to-DMCA-request-%28Collection-of-XP-OEM-SLP-keys%29). Je ne suis pas sûr si le particular vendor clé is required, or if [those provided by Microsoft](http://technet.microsoft.com/en-us/library/bb457078.aspx) will work. Si vous encore have the original installation depuis le OEM, vous pouvez extract the SLP clé they used for installation depuis le registry using a tool like [produkey](http://www.nirsoft.net/utils/product_cd_key_viewer.html).
(Most antivirus seems to complain about produkey, but I've jamais had problèmes avec it.)
[nLite](http://www.nliteos.com/) can help you créer the ISO and be very useful for testing in a VM, but c'est quite a bit more difficult to test the SLP activation avec the VM.
