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!

    My computer:  Windows 7 32bit.

    My question is what programs should be running in the background and what programs should not be running in the background.  There are many running and many that are not running.

    At start-up the CPU is 95 percent and goes down after the programs get done launching.

    The Physical Memory is always at 95 percent during the day.

    At shutdown I get “Waiting for Back Ground Programs to close” than I get “Task Host” hang-up and last night at shutdown I received “explorer.exe” is hanging-up at shutdown. 

    The “explorer.exe” at shut-down started hanging-up this week after an automatic IE update to IE version 11 earlier this week.

    Sounds like your PC has very little physical memory. If, after rebooting, and before running any apps, your PC is reporting that approx. 90% of your memory is in use, then your PC will ALWAYS run slowly as it will be constantly swapping memory to and from disk.

    You may want to consider adding more RAM to your PC or upgrading to a more modern PC.

    If Windows takes a while to shut-down, it's likely caused by a misbehaving add-in. Consider removing unnecessary toolbars, helpers, etc.

    HTH.

    Thanks for your input.

    You’re probably right about the RAM.  It’s an ACER Netbook with only 1.00 GB of RAM.  I use it for email and once in awhile a word document.  Its light weight, great screen resolution, great for traveling with a Jetpack or at Starbucks.

    But do I really need 144 services starting up and running on my computer and what are these services.

    Windows' services provide a wide range of built-in functionality. From network status monitoring to anti-malware. Checking the status of your printers to defragging your HDD.

    If a service doesn't need to do any work it remains dormant and typically consumes little RAM and CPU.

    You or Acer may have also installed additional software that added additional services which may or may not be necessary. Again, uninstall any apps you've installed that you don't need.

    However, understand that netbooks are EXTREMELY low-end devices that combined low end CPUs with very slow HDDs and very little RAM. The net result is, by any measure, a very slow computer.

    Almost any modern day tablet will massively outperform your netbook by a HUGE margin. I think you'll enjoy a FAR better experience if you replace your netbook with something like the Dell Venue 8, 2nd Gen Acer mini tablet (both around the $300 mark) or a Surface2 or similar if you have a little more available cash.
