Hi,
Not sure why you are asking here... we're mostly all other users of VMware's products. We're not employees of VMware nor legal advisors.
Obviously using illegal product keys for Windows XP is ... not allowed or recommended.
Same for running the unlocker in order to be able to run macOS guests.
Should you do this? My advice would be no, but who am I to tell you what to do?
Is it so illegal that it can get you in trouble? Probably not, but that's very much a "it depends" answer as each country has their own rules about that.
Will you get help down here if we know that you are trying to do something illegal? Normally not as it is against the rules of the forum. The forum is hosted in the US and will follow the rules of US justice and the rules set by VMware.
For running Windows guests.. use trial versions of Windows. Those will expire after a while, but if you're testing than that probably doesn't matter.
For macOS guests you need a macOS host in order to be able to run it legally.
If you want to bring your Workstation install back to original (before unlocker), then uninstall VMware Workstation, reboot the host and re-install VMware Workstation.
That's about all I can tell you about it.
What you do with all that info.. is your choice.
Best of luck,
