I have Workstation Pro 15.5, and I have to struggle to keep the Windows 10 Home Edition guest from updating to the latest version. I frequently revert to a snapshot after the Windows client updates because the client is essentially unusable after the update. The start menu doesn't populate!

I've got no problems running Windows 10 Pro 20H2 inside Workstation 16.
15.5 should also work, but try installing the latest VMWare Tools (the link points to newer version than what's distributed with Workstation).
