Can I create my own error class if I need to represent a Windows-specific error?

Yes, you can! Define a custom exception class that inherits from the base `Exception` class (or a more specific exception type like `ValueError` or `TypeError`, if appropriate). This allows you to create a more meaningful error representation for your Windows-specific logic. For example: `class MyWindowsError(Exception): pass`. You can then raise this custom exception when a Windows-specific error occurs. This is far better than trying to rely on a non-existent `windowserror` attribute.
