With the Windows 24H2 update, some users may find that the SMB 1.0/CIFS protocol is no longer enabled by default. SMB 1.0 is an older file-sharing protocol that some legacy applications or devices still rely on. While it’s generally recommended to use newer, more secure versions of SMB, enabling SMB 1.0 may be necessary for compatibility in certain situations.
Here’s a step-by-step guide on how to enable SMB 1.0/CIFS File Sharing Support after updating to Windows 24H2.
Step 1: Open Control Panel
- Press Win + S to open the search bar.
- Type Control Panel and select it from the search results.
- Once in the Control Panel, navigate to Programs > Programs and Features.
Step 2: Access Windows Features
- In the left-hand menu, click on Turn Windows features on or off.
- A new window will appear, listing all available Windows features.
Step 3: Locate SMB 1.0/CIFS File Sharing Support
- Scroll down the list until you find SMB 1.0/CIFS File Sharing Support.
- Expand the option by clicking the plus (+) icon.
Step 4: Enable SMB 1.0/CIFS Client and Server
- Check the boxes for the following options:
- SMB 1.0/CIFS Client
- SMB 1.0/CIFS Server
- Click OK to apply your changes.
Step 5: Restart Your Computer
- Once the changes are applied, Windows will prompt you to restart your computer.
- Save your work and click Restart Now to finalize the configuration.
Important Notes
- Security Risks: SMB 1.0 is an outdated protocol and has known vulnerabilities. It is recommended to enable it only if absolutely necessary and to disable it once you no longer need it.
- Alternative Solutions: If possible, consider updating your devices or applications to use newer SMB versions, such as SMB 2.0 or SMB 3.0, which offer better security and performance.
By following these steps, you should be able to enable SMB 1.0/CIFS File Sharing Support and restore compatibility with legacy systems after the Windows 24H2 update. Always keep your system updated and consider long-term solutions to move away from legacy protocols for enhanced security.
