Why is my password pasted twice if I press crtl+V only once in the RDP logon dialog.

Question

...This always happend if I first right clicked with the mouse in the text field. This issue seems to be quite old and should not be too hard to be fixed.

Hello Daniel,

Thank you for posting question on Microsoft Windows Forum.

Based on the issue description. It is highly probably of that you are triggering a conflict between the local RDP client's UI and the remote session's clipboard monitor, resulting in the paste command being sent twice.

The plausible explanation to this symptom is that when you use RDP, there is a dedicated process called rdpclip.exe running on the remote machine. Its job is to synchronize the clipboard between your local PC and the remote server. When you right-click the password field, two things happen. You give focus to the window. The RDP client checks the clipboard content to populate the "Paste" option in the context menu. This "wakes up" the synchronization process. By pressing Ctrl+V immediately after, you are sending a hardware keyboard command to paste. Because the Right-Click already initiated a clipboard data request (to verify if "Paste" should be enabled in the menu), the remote session sometimes receives that pending data packet plus your manual Ctrl+V command. The latency in RDP causes them to arrive or process nearly simultaneously, effectively dumping the buffer twice.

The following are suggested workaround for this issue.

• Try left-click the password field to focus it, wait a split second, then press Ctrl + V. On the other hand, if you Right-Click, select "Paste" from the menu with your mouse instead of switching back to the keyboard.
• Try to restart the Clipboard Monitor. If the double-pasting persists even without the right-click (which happens if the sync process glitches), you can reset the remote clipboard handler by opening Task Manager on the remote computer (Ctrl + Shift + Esc). Go to the Details or Processes tab. Find rdpclip.exe and End Task. Go to File > Run new task, type rdpclip.exe, and hit Enter.
• Disabling Clipboard Sharing. If you do not need to copy text between your PC and the remote server often, disabling the shared clipboard stops this bug entirely. Open Remote Desktop Connection (mstsc). Click Show Options. Go to the Local Resources tab. Uncheck Clipboard.
