I’ve considered using VirtualBox or VMWare as suggested in Comment puis-je take screenshots of the PC before it boots up?, but this wont allow me to capture a computer-specific login issue*. The aforementioned question also specifically asked for solutions before the PC boots into Windows.
*The “Shut Down” button disappeared from my desktop’s login screen, but that’s an issue for a future question.
Create a new Key called utilman.exe à gauche panel and a new String value called Debugger at the right panel. Then set the path of the snipping tool (see below) as the value of the string.
C:\Windows\System32\SnippingTool.exe
At the Login Screen, Cliquez sur le Ease of Access button, the one next to the Power button en bas right corner of the screen. The snipping tool pops up. Take the screenshot of the Login Screen et cliquez sur Copy button to copy it to the clipboard. You won’t be able to save the screenshot you just took, but vous pouvez still use Clipboard as your middle man to transfer the content.
Log back to your desktop, launch Paint app or any other photo editing or screenshot app you use and paste it.
