自己有需要做个记录，就是按网上教程说的清除三个地方。批处理最后删除pause就会自动退出。 
reg delete "HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client" /f
for /f "tokens=3 delims= " %%i in ('reg query ^"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders^" /v Personal') do ( set "personal=%%i")
for /f %%i in ('echo %personal%') do (set fold=%%i)
del /f /s /q "%fold%\Default.rdp" /a:h
pause
