Can't (re)activate Windows 7 Pro. RRS feed

  • 问题

  • One of our many Windows 7 Pro Dell PC's are all of a sudden telling me it's not genuine.

    When running SLMGR in an elevated command prompt, it tells me it needs to be elevated. I right-clicked and ran it as admin, so not sure how to elevate it more.

    Only thing I managed to do was to remove the current product number, and when I call the phone number MS has for activation, it terminates my call if I don't have an activation screen up, which I can't get to.

    If I right-click Computer and select Properties, it tells me that both Status and Product ID under Windows activation are not available.

    I can clone a hard disk from a similar unit, but would like to not have to do so.

    Can someone come up with a way to make the elevated command prompt work so I can insert the product key?

    This is a Windows 7 Pro PC on a workgroup. It was on a domain, but I removed it hoping I would get the elevated mode that way by not being part of the domain group policy, but that didn't change a thing.

    Thanks for any comments.

    EDIT: Never Mind! - Reinstalling Windows. No sense spending hours trying to work on a broken OS.

  • Hi,


    There are numerous items that can cause a "Windows is not Genuine" error in Windows 7. Dell Original Equipment Manufacturer (OEM) Windows uses a special OEM (system Locked Pre-installation (SLP) key and OEM Basic in/out system (BIOS) Flag for activation of the operating system (OS).


    Download and install the Latest Available BIOS revision for the system then re-run the WGA tool: 

    Issue should be resolved.


    If this does not resolve, please refer to the steps below:

    Click the Start button

    Type: CMD.exe in the start search field

    Right-Click on CMD.exe and select Run as Administrator

    Type: net stop sppsvc and press the Enter key. (You may be asked if you are sure, select yes)

    Type: cd c:\windows\ServiceProfiles\NetworkService\AppData\Roaming\Microsoft\SoftwareProtectionPlatform and press the Enter key.

    Type: rename tokens.dat and press the Enter key.

    Type: slui and press the Enter key.


    After a couple of seconds Windows Activation dialog will appear. You likely be asked to re-enter your product key and/or re-activate. For Dell systems it will auto-authenticate.


    Hope above information can help you.
