PowerShell Commands Tackle Common Windows Issues

PowerShell commands have become essential tools for resolving common Windows problems, such as slow startups, network issues, and storage management.

Repair and Maintenance

To address system freezes, crashes, or Blue Screen of Death (BSOD) errors, running the DISM and SFC commands in PowerShell can repair the component store and replace corrupted system files. The commands are:

• DISM /Online /Cleanup-Image /RestoreHealth
• sfc /scannow

These commands require administrative privileges and may involve checking logs at C:\Windows\Logs\CBS\CBS.log for unresolved issues.

Storage and Networking Solutions

PowerShell can also help identify large files and folders that consume excessive storage space. Commands to list the largest folders and files include:

• Get-ChildItem commands for folder and file size analysis.

For network troubleshooting, clearing the DNS cache and restarting network adapters can resolve connectivity problems. Use:

• Clear-DnsClientCache
• Restart-NetAdapter
• Test-NetConnection

Performance Monitoring and App Fixes

To diagnose performance issues, PowerShell can monitor CPU and memory usage, startup impact, and running services. Commands include:

• Get-Counter for CPU usage
• Get-Process for memory usage
• Get-CimInstance for startup programs
• Get-Service for running services

For fixing broken apps or Start menu glitches, re-registering app packages can be effective. Use:

• Add-AppxPackage for app re-registration
• wsreset.exe to reset the Microsoft Store cache

These PowerShell commands provide precise, controllable fixes for common Windows problems, enhancing system performance and stability.
