All you need is Windows’ built-in ability to capture the contents of your screen, via the PrtScn button on your keyboard. To capture an error message and save it, follow these steps.
- When the error message appears, click the PrtScn button. This will copy a snapshot of your screen to the Windows clipboard.
- Open a program like Microsoft Word, WordPad, or even Paint and select Edit > Paste. A copy of your screen should now be visible on the screen. Save the file as you normally would and use it for future reference.
If you only want to capture the error message window itself (rather than the entire desktop), hold down the Alt key and then press PrtScn and then paste the window into your preferred program.
