    Hi Ron

    that link is coming back as "invalid attachment"

    can you also download and run Kb947821 as well, if it also reports as clean your best bet is a repair install
    Repair Install

    The Macrium activated OS is a great back-up option

    Here's the MGADiag error message when I clicked the copy button:

    Activate Windows 7 by Phone-mgadiag-error.jpg

    Re the Macrium backup question, what I'm getting at is if I could solve this reactivation issue by reverting the current W7 OS to an earlier state before the black screens / faulty MB issue of last week. I have a few Macrium image files from early April [each of which of course is of an activated W7] that I could use. [Remember, I replaced the MB with the exact same model so I don't believe there'd be a compatibility problem]. Or is MS too clever for that to happen?

    I know where the System Update Readiness Tool logs are stored, but I don't have a clue how to read the results .

    Your suggestion of a Repair Install is intriguing. I understand that no files or programs, etc. will be changed, but can the same be said of any of the minor tweaks / customizations I've done over the years?

    If you restore an image then hopefully the restored os will not be corrupt as your current os seems to be.

    As it is a different motherboard you will probably need to reactivate after restoring the image.

    Right you are. Reverting to a pre-black screen/faulty MB W7 Macrium image resulted in a couple of minor changes. The Control Panel > System > Windows Activation area previously read as: "you must activate Windows now." It currently states: "3 days to activate. Also, there is no desktop warning stating "This copy of Windows in not genuine."

    However, previous behaviors exist. 1] clicking on the "activate now" blue link on the System page results in nothing [no panel with activation options]; 2] typing slui.exe in the Start Search windows also results in nothing; 3] running MGADiag results in the same error message; 4] running the CD and REN lines of code did NOT this time result in the error message "The system cannot find the file specified" so this time I was able to finish entering the remaining lines of code. However, the hoped for Windows Activation dialog did NOT appear.

    So, this is all to say that I appear to be a little better off than before, but not much. As Brink has made clear at the top of this thread, the penalty for an unactivated W7 is a black screen desktop. If in fact that's true -- and assuming that I'd still be able to access the Task Bar -- then this will only be a minor inconvenience as I don't use the desktop for much of anything anyway.

    I was hoping the "CD + REN" lines of code fix would do the trick, but sadly no panel with activation options. . . .

    Well, there's the update. I'm open to additional suggestions but hope is running out

    as its a different image
    please rerun sfc /scannow and KB947821 again

    something has changed, your now in the grace period default state, hence the 3 day message

    please run Mgadiag again, can you view the licencing tab page - are the last 5 characters the same as your product code
    i dont believe they will be
    if the above is true -- from an elevated command type
    slmgr.vbs /ipk (your product key)

    really silly question now --- are you fully updated, including Netframework

    Thanks for getting back to me.

    - sfc /scannow returned with this: Windows Resource Protection did not find any integrity violations. Same result as with the previous W7 image.

    - KB947821: I have the log results, but don't have a clue as to how to read them. Please inform.

    Mgadiag results: For better or worse, the product key is a match with my retail DVD. And the product ID as shown on the Mdadiag page matches that shown on the Control Panel > System page. Here's a composite image of both:

    - No, I'm afraid I'm NOT fully updated. I lagged behind that process some time ago.

    - I ran
    slmgr.vbs /ipk + product key and received this message: "Error: 0xc004f050 The Software Licensing Service reported that the product key is invalid"

    Hope the above helps. Continued thanks for your efforts.

    - Ron

    please ensure you have these updates installed

    2019 servicing stack update (SSU) (
    The latest SHA-2 update (

    now that your activation system is "cleaner" i'm hoping its in whats called a "race condition" and that after a cople of days it will untangle itself...

    i would also like you to do this

    from an elevated command

    slmgr /rearm

    this will give you another 30 days grace

    - KB4490628: installed successfully.
    - KB4474419: Windows informed me that this update was already installed.
    - slmgr /rearm: done. 30 day grace period activated.

    Just asking, but how will I know when the OS has become "untangled" ? Again, thanks for your continued help,
