In order to remotely manage Hyper-V on Windows 7, you need to install the Remote Server Administration Tools (RSAT), provided by Microsoft. RSAT enables IT administrator to manage roles and features remotely from a Enterprise, Professional or Ultimate edition Windows 7 or Windows 7 with SP1 workstation.
Now Microsoft has updated the RSAT to support the new features introduced in Service Pack 1 for Windows 7 and Windows Server 2008 R2, which was released in February this year.
