For Visual Studio 2010 and up (including Visual Studio 2012), the VersionInfo extension will check if you have the latest service pack, update and hotfixes installed.
Of course you can manually check the List of available VS2010 hotfixes, or follow the lists maintained by Terje Sandstrom:
- Visual Studio & TFS 2012 – List of extensions and upgrades.
- Visual Studio & TFS 2010 – List of extensions and upgrades.
But installing the Visual Studio 2010/2012: Version and update information tool is much easier.
