After you use the Remote Desktop Connection tool to make a connection to another computer, the name of the computer to which you connected is added to the Remote Desktop Connection Computer box. This makes it easy for you to quickly select the same computer at a later time. However, the Remote Desktop Connection tool does not provide a way to clear the list of computers or remove one or more entries from the Computer box.
1. To remove entries from the Remote Desktop Connection Computer box in the Windows Remote Desktop Connection client, start Registry Editor, and then click the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default
Entries appear as MRUnumber, and are visible in the right pane. To delete an entry, right-click it, and then click Delete.
Additional Note:
The list of all destination connections (including previous connections) are stored in an MRUnumber value in the following registry key:
HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default
Every new connection is given the value of MRU0, and the other values are then sequentially moved down in number. The MRU value can contain a Fully Qualified Domain Name or an IP address of the computer to which you connect. For example:
MRU0 REG_SZ 192.168.1.10
MRU1 REG_SZ computer.domain.com
