Hi,

 

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.

Last but not the least, perform virus scan to remove any trace of infection on your computer, I would suggest you to download Microsoft Safety Scanner from the below link which will help you eliminate any virus/malware infection on the system.
