Common mistakes to avoid

Task Manager shows running processes and a simplified services view, but not full service configuration. Resource Monitor and Performance Monitor provide more granular counters; Device Manager or Event Viewer may be needed for hardware-related faults.

Learners may try to use Disk Management to recover files or think Performance Monitor replaces Task Manager. Also, Local Users and Groups is not available or used the same way on domain-joined machines.

Learners try to use Disk Cleanup to fix fragmentation or use regedit without backups. Emphasize safe practice: export registry keys before edits, prefer GUI tools when available, and use defrag selectively based on drive type.

Learners may assume ping equals DNS resolution; always combine ipconfig/ nslookup with ping. Some environments block ICMP making ping/tracert unreliable; interpret timeouts with caution.
