View Installed Updates on Your Server
To determine what updates have been installed as part of your deployment of Team Foundation Server, you can use the administration console for Team Foundation or you can view the version number of a particular file. The administration console provides more information, but might not be available in certain scenarios, such as during an upgrade from an earlier version of Team Foundation Server. In such cases, you can check the version by viewing the file version number of the Microsoft.TeamFoundation.Admin.dll file.
To view installed updates from the administration console
Open the administration console for Team Foundation.
For more information, see Open the Team Foundation Administration Console.
Under the server name, choose Application Tier.
In the Data Tier Summary section, choose Installed Updates.
The Team Foundation Server Installed Updates window opens.
Review the information in the Name, KB Article, Release, and Install Date columns.
When you have finished viewing the installed updates, choose OK.
Viewing the file version to determine updates
In some circumstances, you might need to determine the update level of your deployment without accessing the administration console. For example, the Installed Updates link in the administration console is not active until after you configure Team Foundation Server. Therefore, you must check the file version of Microsoft.TeamFoundation.Admin.dll to determine what updates are already installed.
To view the file version of Microsoft.TeamFoundation.Admin.dll
Open Windows Explorer (or File Explorer), and browse to \Program Files\Microsoft Team Foundation Server 11.0\Tools.
Expand the sub-menu for Microsoft.TeamFoundation.Admin.dll, and then choose Properties.
Choose the Details tab, and review the information under File Version.
When you have finished viewing the file version, choose OK.
