Visual studio 2015 update 2. Team Explorer not working

Question

I updated VS2015 to update 2.

Upgrade process finished fine, but after launch a lost access to Team explorer.

There is a bug with the following callstack instead.

    An exception was encountered while constructing the content of this frame.  This information is also logged in "C:\Users\volkov.a\AppData\Roaming\Microsoft\VisualStudio\14.0\ActivityLog.xml".

Exception details:
System.InvalidOperationException: The window search was not yet setup for this search host.
   at Microsoft.VisualStudio.Platform.WindowManagement.WindowSearchHost.ThrowIfSearchNotSetup()
   at Microsoft.VisualStudio.Platform.WindowManagement.WindowSearchHost.set_HelpTopic(String value)
   at Microsoft.VisualStudio.TeamFoundation.TeamExplorer.ToolWindowTeamExplorer.OnToolWindowCreated()
   at Microsoft.VisualStudio.Shell.Package.CreateToolWindow(Type toolWindowType, Int32 id, UInt32 flags)
   at Microsoft.VisualStudio.Shell.Package.CreateToolWindow(Type toolWindowType, Int32 id, ProvideToolWindowAttribute tool)
   at Microsoft.VisualStudio.Shell.Package.FindToolWindow(Type toolWindowType, Int32 id, Boolean create, ProvideToolWindowAttribute tool)
   at Microsoft.VisualStudio.Shell.Package.CreateToolWindow(Guid& toolWindowType, Int32 id)
   at Microsoft.VisualStudio.Shell.Package.Microsoft.VisualStudio.Shell.Interop.IVsToolWindowFactory.CreateToolWindow(Guid& toolWindowType, UInt32 id)
   at Microsoft.VisualStudio.Platform.WindowManagement.WindowFrame.ConstructContent()

I tried repair and reinstall. No result.

Also I'm getting exception on launch:

---------------------------
Microsoft Visual Studio
---------------------------
Error HRESULT E_FAIL has been returned from a call to a COM component.
---------------------------
OK   
---------------------------

What else could I check?

我把Microsoft.TeamFoundation.WorkItemTracking.Client.dll放到了Gac，这有帮助。
