Microsoft to Disable SMBv1 in Windows Starting This Fall

Starting this fall, with the public launch of the next major Windows 10

update — codenamed Redstone 3 — Microsoft plans to disable SMBv1 in

most versions of the Windows operating systems.


nternally, Microsoft has been already building Windows versions where SMBv1 — a file sharing protocol Microsoft developed in the early 90s — has been disabled.

For example, Microsoft has disabled SMBv1 for internal builds of Windows 10 Enterprise and Windows Server 2016. These builds are not available to the public and are only for testing purposes.

“This will not reach Insider Flights for some time, and it does not affect released production code at all yet,” said Ned Pyle, Principal Program Manager in the Microsoft Windows Server High Availability and Storage group, who confirmed the company’s plans to Bleeping Computer yesterday via email.

Exact details are not available just yet, as Microsoft is still in the early stages of deciding on a plan of action.

“It is likely to evolve several times inside Flights,” Pyle said. “All of this is subject to change and none of it can be considered plan of record. This is just early guidance.”
