Troubleshooting is an essential skill for anyone working with Windows systems. Whether you're dealing with performance issues, network connectivity problems, or application errors, knowing how to diagnose and resolve these issues is crucial. This article will guide you through some common troubleshooting techniques and tools available in the Windows environment.

Examples:

1. Diagnosing Network Issues with CMD:

   When facing network connectivity issues, the Command Prompt (CMD) can be a powerful tool. Here are some commands that can help diagnose and fix network problems:

   • IPCONFIG: This command displays all current TCP/IP network configuration values and refreshes DHCP and DNS settings. Use it to check your IP address and network configuration.

     ipconfig /all

   • PING: Use this command to test the reachability of a host on an IP network. It helps determine if the network is the issue or if it's a specific application or service.

     ping www.example.com

   • TRACERT: This command traces the path that a packet takes to reach a destination. It's useful for identifying where the connection is failing.

     tracert www.example.com

2. Resolving File Permission Issues with ICACLS:

   File permission problems can prevent applications from accessing necessary files. The ICACLS command can be used to modify file and folder permissions.

   • Example: Granting full control to a specific user on a folder.

     icacls "C:\ExampleFolder" /grant UserName:F

3. Checking System Performance with Task Manager and Resource Monitor:

   If your system is running slow, you can use Task Manager and Resource Monitor to identify resource hogs.

   • Task Manager: Press Ctrl + Shift + Esc to open Task Manager. Check the "Processes" tab to see which applications are using the most CPU, memory, and disk resources.

   • Resource Monitor: Access Resource Monitor from Task Manager's "Performance" tab. It provides a more detailed view of resource usage, including CPU, memory, disk, and network.

4. Using Event Viewer for Application Errors:

   Event Viewer logs system and application events. It's a valuable tool for diagnosing application errors.

   • Accessing Event Viewer: Type eventvwr in the Run dialog (Win + R) to open Event Viewer. Check the "Windows Logs" sections, such as "Application" and "System," for error messages and warnings.

5. Running System File Checker (SFC):

   Corrupted system files can cause various issues. The System File Checker tool scans and repairs these files.

   • Example: Running SFC to repair system files.

     sfc /scannow
