Switching Visual Studio user - Visual Studio Premium

Meanwhile I found it. In addition I had to delete a registry key

hkey_current_user\software\Microsoft\VSCommon\12.0\clientservices\tokenstorge\visualstudio\ideuser

It seems like this key is neither affected by resetting the environment nor uninstalling VS 2013.

From this MSDN Forum post:http://social.msdn.microsoft.com/Forums/en-US/d2ef5828-ce0b-405a-b0b8-9809fc8ac0f7/cant-switch-user-in-visual-studio-2013?forum=visualstudiogeneral

There are two workable options I now use (in order):

As of Visual Studio 2013 Release 4

• Ensure you login correctly using the current user ID it expects first.
• Then logout from the Account Settings option on the account drop-down menu (top right, usually showing your name)
• Now login again using the other account

It appears VS simply does not like to login to a different account while you are already logged in. Just make it happy first :)

Fallback option: You need to run devenv /resetuserdata at the command prompt.

To run the “switch user operation”:

• Close all instances of VS2013 (Check Task Manager to make sure devenv.exe is not running).
• Open a Developer Command Prompt for VS2013.
• Type devenv /resetuserdata and wait for it to complete,.
• Restart VS2013 and follow the usual “sign in” steps (with the desired account).

This process clears the same registry keys (and a few more) suggested by other solutions.
