Remote Desktop is one of the best features of Windows. Unfortunately all the different Windows version of Remote Desktop seem to have a copy and paste bug. Pasting from the local machine to the remote machine in Remote Desktop will just randomly stop working.
I’ve been plagued with this problem for a long time but I never found a way to fix it. Now I found a simple method that works: On the remote machine kill the rdpclip.exe task and restart it. Pasting will immediately start working again!
Kill the rdpclip.exe task whichever way you want. You can use Task Manager, or you can use this one line command to kill and restart it automatically.
taskkill.exe /im rdpclip.exe & rdpclip.exe
