Windows – How to know when I last changed the Windows 10 password

There are two options:

1) Turn your local account into Live ID account. It won't have password hint.

or

2) You can turn it off by changing your password in User Accounts in desktop Control Panel. (But if you do this way, you will lose all EFS-encrypted files, personal certificates, and stored passwords for Web sites or network resources.)

• In desktop Control Panel, click on User Accounts
• Click on Manage another account
• Click on account you want to change
• Click on change the password
• Enter a new password Leave password hint blank
• Click on Change password.

I think I have it, or at least I have enough to figure out what I need.

Get-MsolUser -userprincipalname user@domain.org | select DisplayName, LastPasswordChangeTimeStamp,@{Name=”PasswordAge”;Expression={(Get-Date)-$_.LastPasswordChangeTimeStamp}}

The result looks like this (date and time format will match your computer's):

DisplayName    LastPasswordChangeTimestamp PasswordAge
-----------    --------------------------- ----------- 
User, Name     09-Mar-16 5:48p             42.22:34:10.6964630

.

In order to see all users whose passwords are older than 30 days, use this.

Get-MsolUser -All | select DisplayName, LastPasswordChangeTimeStamp,@{Name=”PasswordAge”;Expression={(Get-Date)-$_.LastPasswordChangeTimeStamp}} | where {$_.PasswordAge -gt “30”} | sort-object PasswordAge -descending

It will list all of the users with passwords older than 30 days and sort the list by the password age.

I hope this helps others as well.
