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

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

Microsoft has said that the last step in removal of SMBv1 has been taken. In the Windows 11 Home Dev preview versions that are out now, you won't be able to use the old file sharing method as default.

 These were the last versions of Windows that had SMBv1 enabled. In all the other versions, this protocol has been replaced by the more secure SMBv3. In June 2017, Redmond revealed intentions to deactivate SMBv1 in most versions of the Windows operating system, after previously blocking it in internal editions of Windows 10 Enterprise and Windows Server 2016.

"I have a pretty big announcement: we've started the final phase of disabling SMB1 in Windows," said Ned Pyle, Principal Program Manager in the Microsoft Windows Server High Availability and Storage group.

"If you install a Windows Insider Dev channel build in any variant of Home Edition, the SMB1 client isn't installed."

Since Windows 10 version 1709 and Windows Server version 1709, SMBv1 is no longer installed by default in Microsoft's operating systems, with later versions of Windows adopting SMBv3.

Ahh that may explain why I suddenly had to reinstall/reactivate it on my win 10.

Mapping network drives suddenly did not work anymore.

SMB 2.0 was introduced in like 2006?

If you still have a device needing 1.0 it's honestly time to upgrade.
