How to remove RDP history

Posted on September 10, 2012 by Gkhan

How to remove RDP history

To remove entries from the Remote Desktop Connection Computerbox 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.

Removing Entries in the Mac Remote Desktop Connection Client

To remove entries from the Remote Desktop Connection Computerbox in the Mac Remote Desktop Connection client, delete the Users:Username:Library:Preferences:Microsoft:RDC Client:Recent Servers file.

Notes

The list of all destination connections (including previous connections) are stored in an MRUnumbervalue 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 192.168.16.60
MRU1 REG_SZ computer.domain.com
