Step 1: Check for Malware
The first step is to check your system for malware. Malware can cause high CPU usage, and it’s important to ensure your system is free from infections. Run a full system scan using a trusted antivirus software and remove any threats detected.
Step 2: Disable Startup Programs
The next step is to disable unnecessary startup programs. These programs can cause high CPU usage, and disabling them can help improve system performance. Open the Task Manager, go to the Startup tab, and disable any programs you don’t need.
Step 3: Clear Temporary Files
Temporary files can accumulate over time and cause high CPU usage. Clearing these files can help improve system performance. Open the Disk Cleanup tool, select the drive where Windows is installed, and select “Temporary files” to remove them.
Step 4: Update Windows and Drivers
Outdated Windows and drivers can cause high CPU usage. Make sure you have the latest Windows updates and drivers installed. Go to Settings > Update & Security > Windows Update to check for updates.
Step 5: Disable Cortana
Cortana is a virtual assistant in Windows 11 that can cause high CPU usage. If you don’t use Cortana, you can disable it to improve system performance. Open Cortana, go to Settings, and turn off “Hey Cortana” and “Keyboard shortcut.”
Step 6: Disable Windows Search
Windows Search can cause high CPU usage, especially if you have a large number of files. Disabling Windows Search can help improve system performance. Open the Services tool, find “Windows Search,” and stop the service.
Step 7: Perform a Clean Boot
If none of the above steps work, you can perform a clean boot. This will start Windows with only the essential services and programs, which can help identify the cause of high CPU usage. Open the System Configuration tool, go to the Services tab, and check “Hide all Microsoft services.” Then, disable all remaining services and restart your computer.
