    Hi

    The key shown in your screenshot ends in T83GX. This is Microsoft’s generic KMS client key for Windows 10 Pro, not a personal retail/OEM activation key. That is why you are getting error 0xC004F074 and Windows is trying to contact an organization’s activation server.

    If this is a work/school PC, connect to your organization’s network or VPN and contact your IT administrator.

    If this is your personal PC, go to Settings > Update & Security > Activation > Change product key and enter your genuine Windows 10 Pro product key. The KMS key itself cannot activate a personal copy of Windows.
