Do you have an entry for a computer in the Windows Remote Desktop Connection client that you don’t connect to anymore? A tweak in the registry will remove it.
- Open the Run Dialog Box using the Windows Key+R key combination then type regedit in the Open: text box and click OK to start the registry editor.
- Drill down the registry tree to HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default, and entries appear as MRUnumber in the right pane.
- To delete an entry, right-click it, and then click Delete.
