Windows 8.1 Enterprise activation RRS feed

  • Question

  • Hi!

    There is PC with OEM license. On the sticker written "windows 8 pro downgrade windows 7 pro". On this PC i have installed windows 8.1 Enterprise. And now i cannot activate windows through KMS server. Error 0xC004F074.

    - kms is available on 1688 port
    - no difference in time
    - different PC with the same windows activating successful
    I'm trying like this:

    slmgr -ipk "MHF9N-XY6XB-WVXMC-BTDCT-MKKG7"
    slmgr -skms kmsserver:1688
    slmgr -ato

    What is needed for successful activating?

    Thank you.

  • Hi

    You say different pc activating? Can you verify the firewalls on the machine? UAC enabled?

  • Thanks for reply.

    UAC and firewall disabled. I'm think, my problem in OEM license.

  • The steps that you have tried are correct. This should be an issue with your OEM license. Have a check on it once.
