Enable SMB 1.0/CIFS File Sharing Support in Windows 11: It refers to the ability of the operating system to interact with network shares using the SMB 1.0 protocol. SMB(Server Message Block) is a network file-sharing protocol that allows computers to communicate and share files, printers, and other resources over a network. SMB 1.0/CIFS is an older version of the SMB protocol, and in Windows 11, it provides compatibility with legacy devices and systems that may still rely on this protocol for file sharing. This includes devices such as older NAS (Network-Attached Storage) devices, printers, and some older operating systems.

IMPORTANT
It’s important to note that SMB 1.0/CIFS is considered less secure compared to newer versions of the SMB protocol, such as SMB 2.0 and SMB 3.0. Microsoft recommends using newer SMB versions whenever possible due to enhanced security features and improved performance.

How to Disable SMB 1.0/CIFS File Sharing Support in Windows 11?

SMB 1.0/CIFS is an older protocol that lacks many of the security features present in newer versions like SMB 2.0 and SMB 3.0. It’s more susceptible to security vulnerabilities and exploits, making it a potential target for cyberattacks and it can be exploited by ransomware and other malware to spread across networks. Many cybersecurity experts and organizations recommend disabling SMB 1.0/CIFS File Sharing Support if not required for specific compatibility reasons. It aligns with best practices for securing networked environments and reduces the likelihood of security incidents related to outdated protocols. The following are the steps to do so.

  • Open Windows Features directly by running the command appwiz.cpl in the Run command box.
    appwiz.cpl
    appwiz.cpl
  • Click Turn Windows Features on or off from the left pane.
    Turn Windows Features on or off
    Turn Windows Features on or off
  • From the list of Windows Features, locate SMB 1.0/CIFS File Sharing Support and uncheck the checkbox next to it. Click OK.

  • Windows will make the necessary changes and apply the changes to Windows 11. If promoted, it is recommended to do a Restart right away. Save your work before that!

Older protocols like SMB 1.0/CIFS may become deprecated or unsupported by software vendors and hardware manufacturers as technology evolves. Disabling this feature helps future-proof your network infrastructure and encourages the adoption of modern, secure protocols.

Take away:

The inclusion of SMB 1.0/CIFS support in Windows 11 ensures backward compatibility with older network infrastructure and devices that may not support newer versions of the SMB protocol. It allows Windows 11 systems to communicate and share files with these legacy devices seamlessly. Happy Coding! Peace out!
