When you use mstsc to connect to a Windows 7 system computer, the atbroker.exe application appears on the desktop of the remote computer.ProgramError. After clicking confirm, the black screen does not have any information. This error has never occurred before during Remote Desktop Connection. Why? After some searches on the network, it is found that the solution is relatively simple-use the common shortcut keys for Remote Desktop:CTRL + ALT + endTo open the Microsoft Windows NT Security dialog box, select cancel, logout, or start task manager.
If the desktop still does not appear after the Task Manager is called up, you can click File> Create task (run...) in the task manager ...), Enter shutdown-r-t 0 in the pop-up form, click OK to restart the computer, and then try again to connect with RDP.
Common shortcut keys for Remote Desktop:

Alt + page up (switch programs from left to right)
Alt + Page down (switch programs from right to left)
Alt + insert (switch programs in the recently used order)
Alt + home (Show "start" menu)
CTRL + ALT + break (switch between the client window and full screen)
Alt + Delete (Windows menu displayed)
CTRL + ALT + minus (-) (place the snapshot of the Client Activity window on the terminal server clipboard. It serves the same purpose as pressing the print screen key on the local computer .)
CTRL + ALT + plus sign (+) (place the snapshot of the entire client window area on the client server clipboard, it works the same way as pressing Alt + print screen on a local computer .)
