Debug Mode, or "Modo de Depuração" in Portuguese, is a critical feature for developers and IT professionals. It allows you to troubleshoot and diagnose issues within the Windows operating system by providing detailed error messages and logs. This article will guide you through the steps to enable and use Debug Mode in Windows, explaining its importance and providing practical examples.

Debug Mode is crucial for identifying and resolving system errors, application crashes, and other performance issues. By enabling Debug Mode, you can gain deeper insights into the system's behavior, which is invaluable for debugging and optimizing your environment.

Examples:

1. Enabling Debug Mode via System Configuration:

   • Open the Run dialog by pressing Windows + R.
   • Type msconfig and press Enter.
   • In the System Configuration window, go to the "Boot" tab.
   • Check the "Boot log" option under Boot options.
   • Click "OK" and restart your computer.

   This will create a boot log file (ntbtlog.txt) in the C:\Windows directory, which can be reviewed for debugging purposes.

2. Using Debug Mode in Command Prompt:

   • Open Command Prompt as an administrator.
   • To enable boot logging, type the following command and press Enter:

     bcdedit /set {current} bootlog Yes

   • Restart your computer to generate the boot log file (ntbtlog.txt).

   To disable boot logging, use the following command:

   bcdedit /set {current} bootlog No

3. Debugging with Windows Debugger (WinDbg):

   • Download and install the Windows Debugger (WinDbg) from the Microsoft Store or the Windows SDK.
   • Open WinDbg and select "File" > "Open Executable" to load the application you want to debug.
   • Use the various commands within WinDbg to analyze the application's behavior, such as !analyze -v for a detailed analysis of a crash dump.

   Example command to load a crash dump file:

   .load C:\Path\To\CrashDump.dmp

4. Using PowerShell for Debugging:

   • Open PowerShell as an administrator.
   • Use the Get-EventLog cmdlet to retrieve event logs that can help in debugging:

     Get-EventLog -LogName System -Newest 50

   • For more detailed debugging, you can use the Get-WinEvent cmdlet:

     Get-WinEvent -LogName Application | Where-Object { $_.LevelDisplayName -eq "Error" }
