I  ncluding printer not working, losing an important document (THAT got me in trouble! ), and emailing. Some mail comes in one, some comes under another.  Then I have to sign out, sign into the other, read emails in both, and switch back and forth.  I assume I must keep microsoft account for updates?  Should I drop the other (same address) or synchronize them (and HOW do I synchronize both accounts?)--or what SHOULD I do to enjoy Windows 10 and the whole computer?
