Seamless mode is not supported with MS Windows servers at present.

Have you tried to use Seamless RDP?
The project does not seem very active, and it never worked properly when
I tried it.

Because of the usability problems with SeamlessRDP, I have never looked
into this possibility.
Assuming that SeamlessRDP can be made to work reliably on Windows-8.1 or
later, I can't see any reason why this could not be made to work with
xpra. How well remains to be seen.
