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.)
- GRTMHOEM_EN.iso (Generic Home OEM)
- GRTMPOEM_EN.iso (Generic Professional OEM)
Install using any media that matches version, use Windows Key Update Tool to activate it as Retail or OEM based on key provided. (True/False)?
Old Method Create vendor specific OEM installer
Backup OEM files from target PC
Create .CAB files of target PC files
- MAKECAB OEMBIOS.BIN
- MAKECAB OEMBIOS.CAT
- MAKECAB OEMBIOS.DAT
- MAKECAB OEMBIOS.SIG
Replace generic OEM ISOs \i386 files with newly created .CAB files
Install using COA key
Backup Activation Files before reinstall
Rename Existing & Replace with backup files after reinstall
Windows Vista/7 (ALL) Retail/OEM (Dell, HP etc.)
- en_windows_7_ultimate_with_sp1_x64_dvd_u_677332.iso (ei.cfg removed)
- en_windows_7_ultimate_with_sp1_x86_dvd_u_677460.iso (ei.cfg removed)
- Backup activation using ABR (Activation Backup and Restore)
- Reinstall version on COA sticker
- Do not enter key during installation
- Restore backed up activation files using ABR
- If files not backed up, use online or phone activation
Windows 8 (ALL) Retail/OEM (Dell, HP etc.)
Just reinstall, activation is taken care of via BIOS(No COA) or use purchased key if you upgraded.
Can anyone confirm/deny the validity of these methods or make suggestions on how to better accomplish activation after a reinstall? I am mainly concerned with XP since the information I have found is rather scattered and I am not sure if its possible to activate a "royalty free OEM" using a generic OEM/retail disk install and Windows Key Update Tool or if I would need to use one of the old methods of backing up the files and altering the install disk.
If there are any known issues with activation on any version using the windows images/techniques I listed can someone please elaborate on them. I am asking because I started a new job that requires re-installing every version of windows on various computers that have OEM and retail versions.
The information I gathered on various forums is rather scattered and contradicting, this is why I am posting this seemingly stupid question that you may think has been answered a million times. I want someone to give me a definitive response so I don't screw someones computer up by remove necessary OEM files.
