IT House April 24 news, Microsoft officially announced that the Insider version of Windows 11 Home Edition has disabled the SMB1 protocol by default, and other versions have been disabled by default, which will be the last moment of SMB1 in Windows.
Since then, there are no longer versions of Windows 11 Insider that have SMB1 enabled by default. In the next major release of Windows 11, SMB1 will be completely disabled by default. Of course, administrators can still reinstall manually.
The SMB (Server Message Block) communication protocol is a protocol developed by Microsoft and Intel in 1987 that can be used to share resources such as files, printers, serial ports, and communications with computers on the network, and has now evolved to SMB3.
Microsoft has been advising administrators to remove support for SMB1 since 2016 because the protocol is unreliable in terms of security and vulnerable to cyberattacks.
IT House has learned that Microsoft recently announced that it will remove SMB1 binaries in future versions of Windows. Windows and Windows Server will no longer contain drivers and DLLs for SMB1.
However, Microsoft will provide additional unsupported installation packages for organizations or users that still need SMB1 connectivity to old factory machinery, medical devices, consumer NAS, and so on.
