How to get rid off the computers shown in the drop down computer list 1

[cchien]

I use remote desktop connection program to access servers all the time. Everytime I access a server by this program successfuly, the program will automatically put that computer's name or IP in the drop down list of the computer field. For security reasons, I would like to get rid off that drop down list so no one knows what server I have accessed by this remote desktop connection program before. Is there a way?
Thanks

It's stored in the registry under an MRU key. For example, in HKEY_USERS\some long SID\Software\Microsoft\Terminal Server Client\Default\MRU0 through MRU9. If you just search the registry key for the value then you should be able to find it.

MS Powertoys has a tool called TweakUI that allows you to cause Windows to not store MRU values, but I don't know if that also includes Terminal Service clients.
