If you don't want the password to expire:
Start Orb>Search box>cmd
When cmd appears in Results above, right-click and choose "Run as administrator"
Stop the Password Expiration - at the command prompt type:
net accounts /maxpwage:unlimited [enter]
You will get a message box: “The command completed successfully” and then you can close the command prompt.
(If you get access error 5, you didn't run Command Prompt as administrator.)
