I have a few files pinned to SumatraPDF on my taskbar and I can't unpin two of them. They seem to be stuck. I've tried removing Sumatra from my taskbar and re-adding it, but all my pins persisted. I tried opening them, but they didn't exist. Then a popup appeared asking if I wanted to remove the dead links, so I clicked yes, but they're still there.
Does anyone know how I can get rid of them?
taskkill /im dwm.exe
ERROR: The process "dwm.exe" with PID 500 could not be terminated. Reason: Access is denied.
I ran it from an admin command prompt.
