How to Use Free System Monitoring Tools to Optimize Your PC
By Justin Phelps
For system monitoring and troubleshooting, Windows offers well-known utilities such as Task Manager, Resource Monitor, and System Configuration (MSConfig). These tools are powerful and easy to use, but they represent only a small part of what system monitoring apps can do. Many system monitoring apps provide levels of depth and detail that will be intelligible and useful only to advanced users, but plenty of other utilities can help average users understand what is going on behind the scenes. Here are some no-cost highlights.
