SFC /Scannow: Initiates the System File Checker (SFC) tool to scan and repair corrupted or missing system files. SFC is a built-in Windows utility that helps maintain the integrity of system files by checking for and replacing any files that are corrupted, damaged, or altered. The /Scannow parameter instructs SFC to immediately scan the system for issues and attempt to repair them automatically. This command is often used as a troubleshooting step to fix various system-related problems on Windows computers.

System performance and repair commands
When systems are running slowly or behaving erratically, these commands diagnose and fix common underlying issues without requiring specialized tools.

For identifying resource problems:
tasklist - Show all running processes with memory usage and process IDs.
tasklist | findstr [process_name] - Filter process list to find specific applications.

For stopping problematic processes:
taskkill /f /pid [process_id] - Forcefully terminate unresponsive processes.
taskkill /f /im [process_name.exe] - Kill processes by executable name.

For system file repair:
sfc /scannow - Scan and repair corrupted Windows system files.
DISM /Online /Cleanup-Image /RestoreHealth - Repair Windows system image corruption.

For disk maintenance:
chkdsk /f /r - Scans for file system errors and bad sectors. May require a reboot when run on the system drive.

When clients report computers running slowly or applications freezing, tasklist quickly identifies memory-heavy processes consuming excessive memory or CPU. 📊💻🔧💸
