Windows 7: Clean install

Clean install

I am going to be doing a clean install on a Dell desktop. I see on the Windows sticker that it says Windows 7 Pro OA.

Does OA mean some type of OEM installation?

Will that product key work if I install Windows 7 Pro from the iso file I got from the Digital River site?

Thanks

I have never heard of the OA before. The Win 7 Pro ISO should work OK with your Product Key from the sticker.

"OA" is synonomous with "OEM" (preactivated) and the product key is for the version (x86 or x64) originally installed.

Type 2 OEM SLP (original equipment manufacturer system-locked pre-installation) license product keys are architecture specific. It makes no difference whether or not the computer is a laptop, netbook, all-in-one, desktop, or rattrap. It is the source of the software installation, not its target that matters. Royalty manufacturers like HP, Dell, Sony, etc. are licensed to use the SLP technology. Type 2 licenses require a valid SLIC (System Licensed Internal Code) in the BIOS on the motherboard. Type 2 licenses cannot be valid on a system that does not have the correct code in the BIOS. If the code in the BIOS becomes corrupted in some way the user must convert the license to Type 8 OEM COA by entering the COA product key to reactivate.

Type 8 license does not read the SLIC table. Non-royalty manufacturers and fabricators (custom builders) use Type 3 System Builder licenses. These are custom builders, consultants, Microsoft Authorized Refurbishers (minimum of 5,000 units), and Microsoft Registered Refurbishers (less than 5,000 units).

Type 5 Retail licenses are used in any transferable license whether sold in a store or through a program subscription such as MSDN, TechNet, BizSpark, etc. The term "retail" does not mean "boxed copy" and it does not necessarily mean re-saleable. It means transferable from one computer to another. Whether or not a license is re-saleable depends on the source of the license. Subscription licenses are always Not-for-Resale.

Type 1 (KMS) and 6 (MAK) licenses are volume licenses (VLK) and are Not-for-Resale licenses.

OA means Win7 was mass-activated Offline at factory, nothing more.

Follow these steps if you'd like to get a Clean Reinstall - Factory OEM Windows
using the Product Key on the COA sticker which MS requires so you can do this and have the activation shifted into their own servers.
