I've been having a similar problem, but in my case i can set the default
printer to a network printer in the control panel just fine. But after
some amount of time (a day or two) the default printer reverts to "xps".
This is w/o a reboot. I have auto-updates turned off, but the updater
does run to "check" what might need to be applied.

Anybody have any ideas?
