Check the "Startup impact" column to see the effect each program has on boot time.
Focus on disabling programs with a high startup impact.
Monitoring System Performance
Task Manager's Performance tab provides real-time graphs and statistics for CPU, memory, disk, and network usage. Use this tab to monitor system performance and identify potential issues:
CPU Performance:
View the CPU graph to monitor usage over time.
Check for sustained high CPU usage, which could indicate a problematic application or process.
Memory Performance:
View the memory graph to monitor RAM usage.
Check for high memory usage that could be affecting system performance.
Disk Performance:
View the disk graph to monitor disk activity.
Look for sustained high disk usage, which could slow down your system.
Network Performance:
