Then, go to the "Startup" tab and click on "Open Task Manager." Disable any startup programs that are not essential and restart your computer.
• Reset Windows Update Components: If the Windows Modules Installer Worker continues to cause high CPU usage, you can try resetting the Windows Update components. Open Command Prompt as an administrator and type the following commands one by one, pressing Enter after each:

net stop wuauserv

net stop cryptSvc

net stop bits

net stop msiserver

ren C:\Windows\SoftwareDistribution SoftwareDistribution.old

ren C:\Windows\System32\catroot2 catroot2.old

net start wuauserv

net start cryptSvc

net start bits

net start msiserver

Additional Tips

Here are some additional tips to prevent high CPU usage by the Windows Modules Installer Worker:

• Schedule Windows Updates: Instead of letting Windows install updates automatically, you can set a specific time to download and install updates. This allows you to choose a time when you are not actively using your computer, reducing the impact on CPU usage.
• Scan for Malware: Malware infections can also cause high CPU usage on your system. Use a reputable antivirus software to scan your computer for any malware and remove it promptly.
• Enable High-Performance Power Plan: Switching your power plan to "High Performance" can optimize your computer's performance and reduce CPU usage. Go to Control Panel > Power Options and select the "High Performance" plan.
