Empty App name+Description+Filename for processes that get run by other process, a good example is Firefox.exe.
If you just launch Firefox.exe, it will first run CommandExecuteHandler.exe, then CommandExecuteHandler.exe will run Firefox.exe, after that you will found out Empty App name+Description+Filename for it, but you can locate where is the file.
This is also happen for smss.exe, but it will not showing App name+Description only.
En...
It look like after restart, only smss.exe don't showing all of this.
Yes, this is long time bug with some windows systems app .
For me smss.exe there no app name , no CPU time , or description but i do get filename for smss .
And you also can't locate the file.
So yup, a strange bug that fixed by reboot, it look like the hibernate of Windows 8(fast start-up) causing this strange issues.
Yes, no location of file, forgot to mention that .
