I have Windows 10 Pro and Windows 10 Home computers, both fully up to date, nether on a Windows Domain.
Home can connect, with the (old) Windows Desktop RD client, to connect to the Pro.
Home will not connect to the Pro with the Windows Store RD Client. The error is that the Username or password is not correct.
I've searched and see there are a lot of problems reported with connecting from the Windows Store RD client and tried some of the options suggested. I've also seen that the Windows Store RD client reputedly has better security, so good it can't connect!
So:
1) How can I connect with the Windows Store RD client?
2) Is it worth the effort of persisting with the Windows Store client or is the old desktop client just as good?
