There are are a few services/processes that simply ignore Process Tamer.
I am seeing this problem now, and I can give a specific example: mstDfrgS.exe, which is a service installed by mst Defrag Home Edition 1.9
. I've configured PT 2.05.02 to force mstDfrgS.exe to low priority, but it never does.
The strange thing is that Sysinternals Process Explorer can set the process priority class of mstDfrgS.exe to 4 (i.e. "low") without a problem. Similarly, the command line utility Process.exe
can set it to 4. So why can't PT do the same?
I haven't tried running PT as a service, because honestly, I don't want to run it as a service. And this isn't a "permissions" issue in that regard anyway. In fact, PT's log doesn't show any attempt to set the priority of mstDfrgS.exe at all. So, I guess we can never mind the question of why the other utils can set the priority and PT can't, and start wondering why PT doesn't seem to try in the first place.
