Enabling SMB1 on Windows 11 is a straightforward process that involves tweaking a few settings in your system. First, you’ll need to access the Control Panel and navigate to Windows Features. From there, you can enable the SMB1 support by checking the appropriate box. Once you’ve done this, a quick reboot will finalize the settings, and SMB1 will be up and running on your Windows 11 machine.
How to Enable SMB1 on Windows 11
In this section, we’ll guide you through enabling SMB1 on Windows 11. By following these steps, you’ll have SMB1 support up and running in no time.
Step 1: Open Control Panel

Once you’re in the Control Panel, finding "Programs and Features" is crucial. This section allows you to manage software and Windows features.
Step 3: Click on Turn Windows Features On or Off
On the left-hand side, click on "Turn Windows features on or off."
This step will take you to a list of optional Windows features. It’s a nifty way to add or remove functionalities from your system.
