About Debug Mode

Debug mode, an advanced troubleshooting option embedded in Windows, is only available for system administrators and advanced users. It is built to find and repair errors in the system. For instance, it can debug Windows apps, drivers, and boot process. There are two types of debugging (user mode and kernel mode).

Tips:
User mode processes stop you from accessing many parts of the system, while kernel mode permits you access any part of the system.

Once enabled, Debug mode allows you to connect to Kernel Debug using debuggers like Debugging Tools for Windows (WinDbg). However, some users report that Windows computer hangs when Debug mode is enabled and Visual Studio freezes when switching to Debug mode. This is confusing.

Note:
If Debug mode is enabled and the debugger hasn’t connected due to user mode exception, the system will hang waiting for a debugger to interrupt from the breakpoint.

In cases like that, you should disable Debug mode manually. It’s also recommended to switch off Debug mode when the task finishes.
