Hi,
my name is Mouad, an independent advisor, and I'm glad to be able to help.
you can change default storage location for apps and games, here is the process:
1 - press both keys Windows + R and type "copy/past" : ms-settings:savelocations
2 - click Ok.
3 - on the drop down for the option "New Apps will save to" select the D: disk letter and click apply.
also you may be need to move applications to the same drive D:, if so here is the process:
1 - press both keys Windows + R and type "copy/past" : ms-settings:appsfeatures
2 - in the list of apps select the application you want and click on the move button.
Hope it helps!
Best Regards,
Mouad.
