I recently found that I can no longer copy text directly from my local machine to the cloud host, nor can I copy text from the cloud host to my local machine.
I am using RDP to connect to a Windows system on the cloud host.
My solution is to restart rdpclip.exe, which works. After restarting, I can share the clipboard with the cloud host again.
In Task Manager, switch to the Details tab, find rdpclip.exe, right-click and select End Task, then click File, New Task, enter rdpclip.exe to restart it.
