I wasn’t aware of any other way of doing it, although I know that it is possible to update Qubes Windows Tools from dom0, I’ve never been sure how to actually install it without downloading from within the Windows Qube itself from the link at Contents/windows-tools.md at master · Qubes-Community/Contents · GitHub
Can you clarify how you have been installing Windows Tools into your Windows 10 Qube to get clipboard sharing working?
