Command Line (DISM): This is the preferred method for many administrators, especially when converting from an Evaluation version. The command DISM /Online /Set-Edition:ServerStandard /ProductKey:XXXXX-XXXXX-XXXXX-XXXXX-XXXXX /AcceptEula is widely cited as the fix for license mismatches. Volume Activation (MAK/KMS):
MAK (Multiple Activation Key): Can be used for Independent (direct connection to Microsoft) or Proxy (via VAMT) activation.
KMS (Key Management Service): Uses a Generic Volume License Key (GVLK)—specifically D2N9P-3P6X9-2R39C-7RTCD-MDVJX for Standard—to activate against a local host server. Critical Technical Considerations
Evaluation Expiry: After the 180-day evaluation period, the system will shut down every hour until a valid key is provided.
Version Mismatch: You cannot activate a Standard key on a Datacenter installation without a complete reinstall or a version downgrade, though upgrading Evaluation to Standard via DISM is supported.
Virtualization: A single Standard license permits one physical host and two VMs, provided the host is used solely for the Hyper-V role.
Downgrade Rights: Users with modern licenses (like Server 2022) can legally use downgrade rights to activate a 2012 R2 instance. Troubleshooting Common Errors
Domain Controllers: You cannot change the edition of a server if it is already promoted to a Domain Controller. You must demote it first.
