If you desire to use blank passwords in Windows, you will soon find that Microsoft has made your life quite difficult. I actually side with them on this topic, as blank passwords create security vulnerabilities. That being said, there are legitimate reasons to need a blank password. Anyway, I will not question your reason(s), but rather tell you how to get on with doing whatever it was you were trying to do.

The technique shown here will get around any error that has to do with blank passwords not being allowed. A couple of examples include – accessing network shares of a user with a blank password and running programs as a user with a blank password.

Start by opening the run dialog, by pressing the windows key and “R” at the same time. Type “secpol.msc”, as shown below, and then press enter. This will open the local security policy manager.


Go to “Local Policies” -> “Security Options” and double-click on “Accounts: Limit local account use of blank passwords to console logon only”.


Change it to “Disabled” and press OK. If you want more information about what this will do, click on the Explain tab in that window.


That is all there is to it! You can now get on to doing whatever it was that needed blank passwords.
