How to Use Windows Debugger
- 1). Open the "Run" program by pressing the "Windows" key and the "R" key on your keyboard at the same time. The "Windows" key is the one with the Windows logo.
- 2). Type "windbg.exe" into the bar in the "Run" program and then click "Run." This will open the Windows Debugger tool on your computer. If you don't already have that program on your computer, you'll have to download it from Microsoft.
- 3). Click "File/Open" and browse through your computer for the program that you want to debug and then click "Open." The windbg.exe software will open up a bunch of source code for the software that you don't need to understand or change in any way.
- 4). Click the "Debug" button and windbg.exe will start to debug the program that you selected.
