The taskhost.exe application(C:\Windows\System 32) consumes 50-60% of the average cpu usage even when the system is idle  and no processes are being run.

Will deleting this application make my computer unstable?

How can  i permanently stop the process ?

Hey Abhishek,

The taskhost.exe is a Task Host which is a generic Host Process for Windows 7 32-bit Services. The full path to this file should be shown in TUT as **C:\Windows\System32\Taskhost.exe.**TASKHOST is a generic process which acts as a host for processes that run from DLLs rather than EXEs. At startup TASKHOST checks the Services portion of the Registry to construct a list of DLL-based services that it needs to load, and then loads them. There can be many instances of TASKHOST running, as there will be one instance of TASKHOST for every DLL-based service or grouping of services (the grouping of services is determined by the programmers who wrote the services in question).

Since this is an integral part of the operating system, I wouldn’t suggest you to delete it.

However, for the high CPU consumption issue, please use Performance Monitor to view performance data either in real time or from a log file.

The new Resource Monitor lets you view detailed real-time information about hardware resources (CPU, disk, network, and memory) and system resources (including handles and modules) in use by the operating system, services, and running applications. In addition, you can use Resource Monitor to stop processes, start and stop services, analyze process deadlocks, view thread wait chains, and identify processes locking files.

A closer look:

View CPU utilization and other performance information**http://windows.microsoft.com/en-US/windows7/View-CPU-utilization-and-other-performance-information**

See details about your computer's performance using Task Manager**http://windows.microsoft.com/en-US/windows7/See-details-about-your-computers-performance-using-Task-Manager**

Last but not the least, perform virus scan to remove any trace of infection on your computer. If your antivirus database is not updated, please update the same and then run the scan. If you don't have antivirus installed, you may opt to download Microsoft Security Essentials on your computer and run it.

Hope this helps!

    the CPU does not run at 50% after WIN7 boots up. It only occurs after opening and exiting any program.

    I thought that it might be 3rd party software but it happens with more then one program.

    the only way to stop this is to go into task manager and close taskhost.exe everytime i exit a program.

    I am out of ideas!

    Still more info: I did a virus/spyware scan this morning (Norton Internet Security); no problems were identified.

    Some additional info: one cpu core is holding at ~100%; the other is near 0%. The only program running other than task manager is Internet Explorer (with two tabs open).

    I have the same taskhost.exe problem. I recently upgraded an XP system to Windows 7. I installed the OS and all apps from scratch. Taskhost.exe consistently (over a couple weeks) uses ~50% of the (dual core) cpu.  I have monitored it using task manager and resource monitor. Taskhost uses 10-11 threads and 50% of cpu. I did an upgrade install of a Vista machine to Win 7 and do not have the same problem on that machine.

    Why is taskhost using so much cpu, and what can I do to fix the problem?
