Disabling the SMB Protocol in Microsoft Windows

What is SMBv1?

SMBv1 specifies a part of your Windows installation that is responsible for accessing documents on other computers in your house (network), and lets them access yours.

Why remove or disable it?

The SMBv1 protocol is very outdated. Modern computers use newer, more secure protocols that are not known to be vulnerable to exploits. Disabling the SMB protocol will allow you to prevent your PC from being accessed this way.

How do I disable it automatically?

We have created a small tool to disable SMB on all operating systems. You can download the DisableSMB tool using the link below.


A Tutorial for using this tool can be found below.

This tool does not need to be installed or run more than once. It simply disables the SMB protocol automatically.

How do I disable it manually?

If you are using Windows 8.1 or Windows 10, you can disable SMB manually using our recently released tutorials here.

Users of Windows Vista, Windows 7 and Windows 8 can manually disable SMB with Powershell using the tutorial below.
