How to fix Taskhostw.exe high CPU usage?

Issue: Hello. I have this taskhostw.exe file always running in the back, and it causes an extremely high CPU. A few miles are running at the time, and the CPU is always more than 60%. Is it a virus or something important for the OS? Help!

Solved Answer

User reports and complaints show that Taskhostw.exe's high CPU usage is a problem.[1] Windows system runs a few processes at the time, and those can be found on Task Manager, which is not uncommon since the machine needs many functions at one time. However, suspicions arise when some of the files and processes use high resources or appear to be related to a third-party application or suspicious program instead of the OS.[2]

Taskhostw.exe high CPU usage issue is triggered by a Task Host Process that is the executable users notice running in the background. This is the Microsoft-developed file for Windows and the process recognized as a Host Protocol. It is related to other DLL files and Dynamic Link Library services.

These dll files are important because the operating system needs them to launch certain functions, finding files, processes, running programs. Multiple instances of the same file can lead to usage of resources, and often such issues can indicate that cyber infection is the one that triggers the problem since trojans tend to be masked as exe files. So you might want to run an anti-malware tool scan to fix Taskhostw.exe high CPU usage.

Some of the issues with this executable file also appear as particular error messages:

  • Taskhostw.exe – Access Denied
  • Taskhost.exe – Application Error
  • Taskhost.exe – Error.

It is possible to fix Taskhostw.exe high CPU usage. It is not a virus, but checking the machine with an AV tool is always a good idea. Other solutions for the problem include file repair procedures and restoring the PC to a previous state. Make sure to follow these steps below and double-check if the issue is occurring after you take action.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
