Threadmaster 1.12

ThreadMaster
Monitors Threads and handle CPU overload on a per application basis. 
This function is primarily indented for Terminalservers hosting multiple users.

A single user is capable of hogging all of the processor resources. The result will be a reduction in the quality of service experienced by all other users on the server. ThreadMaster can help you to deal whit this situation.

ThreadMaster monitors all running applications, and detects when the application has started using excessive processor resources. It dynamically track and hunt down the offending thread, and clamp the CPU for this thread. This feature ensures that other users can remain working without noticing anything. The clamped process will eventually finish, and the clamp will be removed automatically. 

Administration of ThreadMaster is extremely simple, the behavior is in general controlled by only two key parameters. 
The first parameter instructs ThreadMaster to monitor application activity over a time period. 
The second parameter is the allowed maximum CPU utilization for the process over the given time.

Configuration
ThreadMaster has no GUI interface, all configuration is done by using a well known tool "Regedit".
Changing  registry keys not described in this section, may cause serious problems. Use Registry Editor at your own risk.
After any changes in the configuration please restart the ThreadMaster service.
