Hi folks Here is the situation: Sometime in 2014, my brother took his PC to a repair shop. To make a long story short, the store sold him a Windows 7 Home Premium OA (What does the OA mean BTW?). The store installed the windows for him on his PC.

Hi folksHere is the situation:Sometime in 2014, my brother took his PC to a repair shop. To make a long story short, the store sold him a Windows 7 Home Premium OA. Chrishan Forever Album here.

The store gave him an ordinary DVD --nothing preprinted on it like a commercial DVD one would buy. Just a standard DVD on which Windows 7 is written by hand on it. Affixed to the sleeve containing this DVD is a COA sticker with a product key on it. Sims 4 Highly Compressed more. It says on the COA 'Windows 7 Home Premium OA' (do not know what OA means as I said before). It also says on the COA 'Acer Group'.

My brother's PC is not a Acer. It is a home build, originally with Windows Vista on it. Vista was then replaced by that store with the above described Windows 7. My questions are: Question 1 Is this a valid Windows 7 key that he could use to reinstall his Windows on his PC (the one on which the windows was first installed)? Question 2 Could he use it (the key) to install this windows on a completely different PC (new parts including new motherboards etc.)?

Question 3 Does this looks legitimate to you folks? I do not know what to think but it sure looks kind of fishy to me? OA = OEM Activation It's the version that comes from the big oems (Dell, HP, Acer, etc.) and is preinstalled using a SLIC key embedded in the BIOS, thus not requiring activation after installation. However, it only works on those systems with the correct SLIC key. Looks like that repair shop copied an Acer DVD and peeled the sticker off, then put it on your brother's system. Very much not legit. The key has most likely been used more than once and is now blacklisted by Microsoft.

I'd further wager that that shop used an activation crack to hide that fact.

If the key was blacklisted by Microsoft, how come he still can use it and get all software updates for his Windows?
