    Can't Activate Windows, even though I used a valid key


    Pretty much what the title said.I used a key to Activate my Windows Home, it seemed like it was working at first until I took a look at it.Not only had it not activated but my Windows Home had been changed to a Pro, and they are showing a different key than I used originally.I have no idea what to do.I tried chatting to Microsoft Support but I wasn't able to talk to anyone.Any advice would be appreciated.

    :)

  3. Windows 7 Activation Key Validation

    We don't work for Microsoft and Microsoft doesn't even look at these Windows 7 forums.

    The way to tell if a product key is genuine is to install the matching operating system and activate it with the matching product key.

    There is no public list of product keys kept as to their status.

    If you have a Retail Windows 7 installed and activated, also read this:

    Description of the update for Windows Activation Technologies - Microsoft Support

    Windows Activation Technologies helps you confirm that the copy of Windows 7 that is running on your computer is genuine. Additionally, Windows Activation Technologies helps protect against the risks of counterfeit software. Windows Activation Technologies
    in Windows 7 consists of activation and validation components that contain anti-piracy features.

    Note For an Enterprise customer who uses Key Management Service (KMS) or Multiple Activation Key (MAK) volume activation, we generally recommend to NOT install this update in their reference image or already deployed
    computers. This update is targeted at consumer installs of Windows using RETAIL activation.


    Cheers.

    Can't Activate Windows, even though I used a valid key

    activate windows 7 oem key

    Win7 and Vista. It did not work with XP, OEM and Retail discs were different for XP(and anything pre-XP).

    If it is already installed, you can enter it when you activate.

    Is it saying the key is not valid or is it failing activation? A screen shot of the error it is giving you would help a lot.
