Microsoft enters “final stage” to disable SMB1 file sharing in Windows 11

Zoom / Microsoft disables SMB1 in new versions of Windows 11 Home.


Most Windows 11 previews focus on adding features, but sometimes Microsoft uses it to remove stuff. Users installing the latest builds of Windows 11 Home Insider will find that support for version 1.0 of the venerable SMB file sharing protocol is now disabled by default, which may disable file sharing for older storage devices network. Posted by Microsoft Program Manager Ned Pyle details The reason for the change and its impact on users.

Microsoft has already disabled SMB1 by default in other versions of Windows. The SMB1 server service has been removed from all versions of Windows From 2017Customer service was disabled on Windows 10 Pro editions from 2018. The Home editions of Windows client finally arrived because it would cause consumer pain among people still using very old equipment, a group that will not understand probably not why they can’t,” Lyle wrote. Connect your new Windows 11 laptop to your old network hard drive. “

SMB1 has long been superseded by newer, more secure versions of the protocol; SMB2 was introduced in 2007 and version 3.1.1 was added to Windows 10 in 2016. But the original is still sometimes used by older servers and equipment – and if the hardware is old enough to rely on SMB1 , it is probably obsolete. that we do not take care of its maintenance or upgrading.

Currently, the SMB1 feature can still be manually installed by users and system administrators who need it, and if you’re using SMB1 on a computer you’re upgrading to Windows 11, the upgrade won’t disable the feature. The next step in the transition will go even further by completely removing the DLL files and drivers needed to support SMB1 from the operating system. Pyle writes that the company “will provide an unsupported out-of-band installer package for organizations or users who still need SMB1 to connect to old factory machines, medical equipment, consumer NAS, etc. “
