No clue, but you only gotta run it once so if you’re concerned you could run it get the .auz and then go back to a previous restore point, could also throw it in virustotal and check the behavior tab to check that ur copy isn’t dropping weird files in places it shouldnt or anything like that before running on your system
Think most the time people replace the patch exe or the installer with malicious version since that’s low hanging fruit, wouldn’t be too worried over the keygen tbh
The first use-case that came to mind for me is research. A distraction-free dedicated application for wikipedia could be a great way to keep organized, especially if new features are added and expanded upon over time that go beyond the typical browser experience.
It’s not a workflow for everyone and if wikipedia is something that’s usually just accessed through other search engines then this probably won’t be all that useful to you.
