This happens from time to time: I run a simple taskkill command (as administrator) like this:
taskkill /im sidebar.exe /f
But get the following:
ERROR: The process "sidebar.exe" not found.
Also tried without ".exe". I see the process in Task Manager:
Killing the process from Task Manager works.
I suspect it happens when the process appears stuck (because that's when I kill it), but it's still strange and inconsistent.
I run Windows 7 Professional SP1 64bit.
