If you're working in IT Support or preparing for a Helpdesk role, these commands are essential for daily troubleshooting

When a PC is Slow or Freezing
• "temp" / "%temp%" → Clear temporary files
• "prefetch" → Remove cached system files
• "cleanmgr" → Run Disk Cleanup
• "taskmgr" → Check and end heavy processes
• "services.msc" → Manage Windows services
• "sfc /scannow" → Repair system files
• "chkdsk /f" → Fix disk errors

When Internet Isn’t Working
• "ping" → Test network connectivity
• "ipconfig" → View IP configuration
• "ipconfig /release" → Release current IP
• "ipconfig /renew" → Renew IP address
• "ipconfig /flushdns" → Clear DNS cache
• "nslookup" → Troubleshoot DNS issues
• "tracert" → Trace network route
• "netsh int ip reset" → Reset TCP/IP stack

Pro Tip:
Troubleshooting isn’t just about restarting devices — knowing the right command at the right time is what sets a professional IT technician apart.
