Key Steps to Troubleshoot Slow Computer Performance on a Windows System

1. Check Task Manager: Open Task Manager to identify any processes or applications consuming high CPU or memory usage.
2. Run Disk Cleanup: Use the built-in Disk Cleanup tool to remove temporary files and free up disk space.
3. Update Drivers: Ensure all device drivers are up to date to optimize system performance.
4. Scan for Malware: Run a full system scan using a reputable antivirus program to detect and remove any malicious software.
5. Disable Startup Programs: Disable unnecessary programs from starting up with Windows to improve boot time and overall performance.
6. Check for Updates: Install Windows updates and patches to address any known performance issues or security vulnerabilities.
7. Defragment Hard Drive: Use the built-in Disk Defragmenter tool to optimize the arrangement of data on the hard drive for faster access.
8. Check Hardware: Verify that all hardware components, such as RAM and hard drive, are functioning properly and not causing performance issues.
9. Monitor Temperature: Ensure that the system is not overheating, as high temperatures can degrade performance.
10. Perform System Restore: If all else fails, consider restoring the system to a previous state before the performance issues began.

By following these key steps, you can effectively troubleshoot and improve the slow computer performance on a Windows system.
