tracert google.com
pathping microsoft.com

Pathping combines features of ping and tracert, providing more detailed information about network latency and packet loss at each hop.

Disk and File System Management

Check Disk (chkdsk)

The chkdsk utility checks file system integrity and can repair logical file system errors. It's particularly useful for diagnosing and fixing disk-related issues.

chkdsk C: /f /r

Parameters:
- /f fixes errors on the disk
- /r locates bad sectors and recovers readable information
- /x forces the volume to dismount first if necessary

System File Checker (SFC)

SFC scans and repairs corrupted Windows system files, making it essential for resolving system instability and application crashes.

sfc /scannow

This command:
- Scans all protected system files
- Replaces incorrect versions with correct Microsoft versions
- Requires administrator privileges
- May take 15-30 minutes to complete

Deployment Image Servicing and Management (DISM)

DISM repairs the Windows image when SFC cannot complete repairs. It's a more comprehensive tool for system recovery.

DISM /Online /Cleanup-Image /RestoreHealth

Performance and Process Management

Tasklist and Taskkill

These commands provide command-line alternatives to Task Manager for process management.

tasklist
tasklist /svc
taskkill /im processname.exe /f
taskkill /pid 1234 /f

Benefits include:
- Remote process management
- Scriptable process control
- Detailed service-to-process mapping
- Force termination of unresponsive applications

Performance Monitor (typeperf)

Typeperf writes performance data to the command window or a log file, useful for monitoring system performance over time.

typeperf \"\\Processor(_Total)\\% Processor Time\" -si 1 -sc 10

Advanced Troubleshooting Commands

Windows Update Troubleshooter

The Windows Update Diagnostic tool can resolve update-related issues through command-line execution.

msdt.exe /id WindowsUpdateDiagnostic

Power Configuration (powercfg)

Powercfg manages power settings and can generate detailed energy reports to identify power-related issues.

powercfg /energy
powercfg /batteryreport

The energy report identifies:
- Common energy-efficiency problems
- Device drivers preventing sleep
- Processor power management issues
- USB selective suspend problems

Driver Query (driverquery)

This command displays information about installed device drivers, helpful for identifying problematic drivers.

driverquery
driverquery /v
driverquery /fo csv > drivers.csv

Automation and Scripting Capabilities

Batch File Creation

Combining multiple commands into batch files can automate complex troubleshooting sequences. For example, a system health check batch file might include:

@echo off
echo Starting System Health Check...
systeminfo > system_report.txt
ipconfig /all >> system_report.txt
netstat -an >> system_report.txt
echo System check completed. Results saved to system_report.txt
pause

PowerShell Integration

Modern Windows troubleshooting increasingly leverages PowerShell, which offers more advanced capabilities:

Get-WmiObject -Class Win32_ComputerSystem
Get-Process | Sort-Object CPU -Descending | Select-Object -First 10
Get-NetTCPConnection | Where-Object {$_.State -eq 'Established'}
