Scenes
Windows has its own mstsc remote desktop connection. After a long time, there will be more and more records. Some servers are no longer in use, or the IP has changed, but the records are still kept, so that adding a new server cannot record the IP.
solution
1. Close all remote desktop connections first.
2. Press the Win+R key to bring up the run window
3. Enter regedit to bring up the Registry Editor
4. Enter "Computer\HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\Default" above the registry manager, and you can see all remote records
5. Select the ones that do not need to be saved, right click and delete
