How to use MSCONFIG

System Startup

Built into Windows is a special tool called the “Microsoft System Configuration Utility” or simply “MSCONFIG.” Designed to help you troubleshoot problems with your computer, MSCONFIG can also be used to ensure that your computer boots faster and crashes less.

To get to it you need to click Start > Run > msconfig

Most people know that the more programs you have running on your computer at once, the more likely it is that your computer will either run slowly or even crash. What most people don’t know is that every time you boot your computer a whole mess of “hidden” programs load in the background. Some of these hidden programs are essential, but most aren’t. Turning off some of these hidden programs can significantly increase your computer’s performance and reliability.

Open your registry editor. Start > Run > regedit

If you’ve actually opened your registry editor, please navigate as follows:

HKEY_LOCAL_MACHINE > SYSTEM > ControlSet001 > Control > Lsa

Find the registry key labeled “LimitBlankPasswordUse” and change the value from 1 to 0.

Registry Edit

Then you’ll need to repeat the above steps using the following registry path as well:

HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Lsa

Again, change the registry key “LimitBlankPasswordUse” from 1 to 0.

That it, we’re all done. Now make sure that this computer’s user account doesn’t have a password set (Control Panel > User Accounts > Remove your password).
