Note

Installations of KMS on Windows Vista, Windows 7, Windows 8, Windows 8.1, Windows Server 2008, Windows Server 2008 R2, or Windows Server 2012 must be updated in order to support activation of clients running Windows 10 or newer client or server operating systems. For more information, see Update that enables Windows 8.1 and Windows 8 KMS hosts to activate a later version of Windows. Installations of KMS On Windows Server 2003 cannot be updated to support activation of clients running Windows 8, Windows Server 2012, or newer operating systems.

Windows Server 2008 R2 KMS keys follow the same hierarchy (groups A, B, C) as Windows Server 2008 with the addition of the Windows Server 2008 Datacenter without Hyper-V™, Windows Server 2008 Enterprise without Hyper-V, and Windows Server 2008 Standard without Hyper-V. The primary difference to note is that Windows Server 2008 R2 KMS keys can be used to activate a KMS host that will in turn activate Windows Server 2008, Windows 7, and Windows Vista.

Windows Server 2008 and Windows Vista keys cannot activate Windows 7 or Windows Server 2008 R2 systems.

Windows Vista and Windows Server 2008 cannot activate Windows 10 or Windows Server 2012 R2 operating systems.
