Windows 7: Sysprep/OOBE - Installing new hardware

Sysprep/OOBE - Installing new hardware

Back in February I got a new case, mobo, and RAM to upgrade my machine, and after I set them in, I was getting a BSOD loop. I don't remember the exact way that I went about the Sysprep, but I used it to wipe the old mobo drivers so that the new one would install. This ended up working and all was fine.

Just yesterday I purchased a new Processor that fits the FM2 socket, it is 64 bit allowing me to use all of the RAM I can on my machine, and I am concerned that I may need to Sysprep again. It was a handful of months ago, but as I said, I don't recall the whole procedure.

My question is, will I even need to run Sysprep in the case of a new CPU; and if so, which Sysprep path do I take for this?

Hi RDLG004, welcome to the Seven Forums.

To completely wipe and delete all hardware related drivers and force Windows to reinstall them you need to use the generalize switch with sysprep:
%windir%\system32\sysprep.exe /generalize /oobe /reboot
The above command would cause Windows to reboot in OOBE mode removing all hardware related information. This tutorial tells you more about generalizing a Windows setup: Windows 7 Installation - Transfer to a New Computer

warning   Warning
Using sysprep with generalize switch causes Windows 7 to lose all activation information, and it needs to be reactivated afterwards. If your Windows 7 is an OEM version, you might not be able to reactivate it, at least not without phone activation option.

Thanks Kari,

This is actually the procedure that I used to install my new mobo! Worked out great and all is well.

My question now is: Is this procedure necessary for upgrading just the CPU specifically?

If the motherboard remains the same, only the processor is replaced, I would not bother. Windows should be OK with new CPU. Reason: only driver involved is the chipset driver and it will be the same as before.
