Hi, I have developed a windows tool, which is occupying the high cpu usage while running. Sometimes other programs are being struck when running the tool. The tool does many process in the system. But i dont want to take more usage of CPU. Application is in final stage. Please provide solution for my problem.

Thanks in Advance.

without knowing what you have developed it will be very difficult to provide a solution.

a possible issues could be if you are running continues loops, the cpu usage will be high. 

To get around this, you could convert this into a windows service with a timer to run every x seconds/minutes.  You could leave it as an application and run as a scheduled task to run every x seconds/minutes.

Are you doing something that would be expected to be processor intensive?  Have you profiled your application and done Big-O analysis of your algorithms?

Leaving aside the issue of efficiency, you can improve responsiveness to other applications on the PC by including a call to sleep for say 5 milli-seconds in your main loop.

See http://msdn.microsoft.com/en-us/library/system.threading.thread.sleep.aspx

If your application is WinForms, then it would have been best asked at:

• Windows Forms http://windowsclient.net/
• MSDN  http://social.msdn.microsoft.com/Forums/en-US/category/windowsforms/

FIrst you have to move processor consuming processes to a seperate thread

second you set the thread periorty to lowerst ( or better leave it as a user setting )

3rd use threadpool.queueworkitem

4th you can consider the background worker control

consider upgrade CPU . this is a no-coding solution
