Taskhost.exe High CPU Usage Windows 7 Fix

Are you experiencing high CPU usage on your Windows 7 due to the Taskhost.exe process? This article provides a fix for this issue.

Repair Corrupted or Altered Files

Another method to repair corrupted files is to use the Deployment Image Servicing and Management (DISM) tool. Open Command Prompt as an administrator and type “dism /online /cleanup-image /restorehealth” and press Enter. This will repair any corrupted system image files.

If you suspect that malware may be causing the issue, run a full scan with your antivirus software to detect and remove any malicious files. It’s also a good idea to update your antivirus definitions and perform a scan in Safe Mode for thorough detection.

In some cases, a corrupt user profile can cause high CPU usage by taskhost.exe. To fix this, you can create a new user account and transfer your files to the new account. Go to Control Panel, click on “User Accounts,” and select “Manage another account.” Then, click “Add a new user in PC settings” and follow the prompts to create a new user account.

If you’re still experiencing high CPU usage after trying these methods, consider using a reliable system optimization tool to scan for and repair any system errors or file corruption. This can help improve overall system performance and resolve any underlying issues causing taskhost.exe to use high CPU resources.

Run System File Checks and PowerShell Scans

First, open PowerShell as an administrator by searching for it in the Start menu, right-clicking on it, and selecting “Run as administrator.”

In PowerShell, use the command “SFC /scannow” to run a system file check. This will scan for and repair any corrupted system files that may be causing the high CPU usage.

If any suspicious processes are identified, it’s important to address them immediately. This may involve running a full antivirus scan, using malware removal tools, or manually removing the malicious files.

In addition to these steps, it’s also a good idea to regularly update and run antivirus software to prevent any future issues with high CPU usage.
