Disable Password Expiry in Windows Server 2008 r2

We have some servers for testing purpose. We don't want to change the password all the time. So we disabled the Password Expiry policy.

How to disable the Password Expiry Policy?
- Go to Start -> Run -> gpedit.msc, this will load the Group Policy Editor
- Expand sections to Password Policy
      = Computer Configuration --> Windows Settings --> Security Settings --> Account Policies --> Password Policy
- Set 'Maximum password age' to 0 to totally disable expiry

Now your password expiry policy is disabled
