Microsoft disables 30-year-old SMBv1 protocol by default in Windows 11

Microsoft has announced that the final step has been taken to completely abandon SMBv1. Starting today, the legacy file sharing protocol will no longer be enabled by default in Windows 11 Home Dev preview builds. These were the last versions of Windows with SMBv1 still enabled, in all other versions this protocol was replaced by the more secure SMBv3.

made Ned PyleThe Main Program Manager in the Windows Server High Availability and Storage group. “If you install a Windows Insider Dev channel build for all variants of the Home Edition, the SMB1 client will not be installed.” This should become standard on all later versions of Windows 11 after feedback from Insiders.

In the future, all binaries will also be removed and the necessary drivers will no longer be present in Windows. An unsupported installation package will be available for older hardware that still relies on the protocol. A list of manufacturers and products that still require SMBv1 has been shared so users can avoid it.

These plans were announced in 2017, and in February SMBv1 was disabled from Windows 10 version 1709. They get the following error message when trying to connect to a device that only supports SMBv1:

You cannot connect to the file share because it is not secure. This share requires legacy SMB1 protocol, which is not secure and can expose your system to attacks.
Your system requires SMB2 or higher. For more information about solving this problem, see Solving this problem. https://go.microsoft.com/fwlink/?linkid=852747
