Allow a Blank User Password for Scheduled Tasks

To allow blank passwords for a scheduled task in Windows 11, you need to disable a security setting in the registry. A simple Windows Registry key controls whether blank passwords can be used for local account logins, including scheduled tasks. By disabling this setting, you can allow the scheduled task to run without a password!

How to Disable the Password Requirement via the Windows Registry Editor:

1. Open Windows Registry Editor:
   Press the Windows key, type regedit, and press Enter.
   
   
2. Navigate to and Edit the Registry Key:
   
   
1.  Navigate to the following key
   HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa
   
   
2. Locate the Limitblankpassworduse value
   You should see a value named:
   Limitblankpassworduse
   
   
3. Change the Value Data
   Double-click on: Limitblankpassworduse
   Change the value data from 1 to 0
   
   
4. Click OK - Save the changes
   
   
3. Restart your computer!
   *This is recommended for the changes to take effect.

Final Thoughts

Allowing scheduled tasks to run without a password can be useful in specific scenarios, especially for automation on local machines or lab environments. However, always consider the security implications before making changes to system policies. Use this tweak responsibly and only on trusted systems.
