Hi again Mike,
Did some quick looking and found this link:
Link Removed
It shows how to get the Password settings up including expiration/expires never up via the Command line. It cleverly uses the
NET USER & WMIC commands to do so.
You can check this out and let us know if it helps you to solve your friend's problem. I did verify that the
lusrmgr.msc snapin does fail on my W10 Home (on my laptop) and I get the same error message your friend gets. So, I guess we need to know exactly what version of W10 he's getting the message on.
If he gets it on Pro/Enterprise edition, you could try this little gem and see if you can bypass the snapin altogether.
