How do I change my password in Windows 10?

Solution to this is a little weird.

1.  click the magnifying glass to search.
2.  type control panel in the search window
3.  Choose User Account, then 
4.  Choose User Account; then here's the weird part;
5.  Choose Manage Another Account
6.  Choose your account; 
7.  Now choose Change the password, then everything goes as you probably expect it would.

Good luck!
