    Hello.

    I have acquired an used Asus netbook with Windows 7 Home Premium, but the key on the Certificate of Authenticity is partially unreadable. I can clearly see the last 3 blocks and the last 2 characters of the 2nd block, but everything else is unreadable. I can see them a little, but not clearly. I have tried running various combinations of keys through the Ultimate PID checker, but haven't got anything valid. So, is there any software that can try to recover a partial product key if a pkeyconfig is provided? Theoretically, brute-forcing combinations should be possible, but I don't have the time to do it manually.

    Why don't you (legally) go for the OEM:SLP activation??

    I'd like to have a spare copy of the COA key just in case.

    You could call to the Activation Center of Microsoft and ask the Operator for to clarify the Product Key for you! You may need to make a photo of that COA Sticker and send them by Chat/e-Mail or so.

    I had done that a few times in the past via MS Singapore Activation Center and that worked well.

    Normally, for an Laptop with an OEM License you could use the standard Product Key for that Windows 7 version which were pre-installed already. That's what Tito told! Just follow the advice about OEM:SLP Activation on this forum

    Did you try Googling "Find Windows 7 Product Key"?

    Hmm, I guess I could try that if I were to install Home Premium somewhere. Don't really plan to do that anytime soon though. Is there anything else I could do?

    Every guide assumes that Windows is already installed, which it isn't. Even if it was, I'd be given the SLP key.

    Sorry, your post stated you got a netbook with Windows 7 Home Premium and I assumed it was already loaded.

    as long as the sticker exists, you are 'legal' to install that edition, doesn't matter what method of activation you use. SLP is easiest.

    can you upload a clear photo showing the first 2 blocks? so that we know how unreadable it is. if some are in guessable form then a brute-force is feasible.

    What a waste of time and effort that would be along with discussion again about brute force keygens e.c.t. lets face it he will never get original oem:coa key back.

    given we have loaders, yeah it is silly but i did have success recovering a few keys from blurry image of coa stickers before
    the sellers' fault for not erasing part of the key (selling coa exclusively is illicit anyway)
