Win11 Home Edition “minus” SMB What is it?

There are many partners who like to try Win11 preview version, recently someone found a problem that the SMB protocol is missing in the Home Preview version. For most of the partners, this name is so strange, what exactly is it for? What if you need it after it has been streamlined? Let’s talk about it today.

01

The full name of SMB is Server Message Block, a protocol developed by Microsoft and Intel in 1987, mainly as a communication protocol for Microsoft networks. As you can see from the current Windows setup interface, it is now mainly used as a file sharing service.

02

It has many applications, such as data transfer between Windows PCs can use the SMB protocol, in addition to other platforms, such as Android systems can visit each other across platforms as long as they install applications that support the protocol, and that’s not all, in fact, Unix and other systems, including the native Unix dual system, can share files through this protocol.

03

Why would such a useful feature be streamlined away? The reason should be multifaceted, such as look at the release time, you will find it really old, so security is really a bit worrying, and Windows Home Edition high-end network capabilities, security capabilities are slightly less than the professional version, so Microsoft should think that this feature is less important to the Home Edition first, followed by more insecure.

04

So, if SMB is disabled, and what impact will it have? Here we must first explain that the disabled is SMB 1.0, its problems have long existed, from the era of Win10 is not open by default, and the default open SMB direct connection function, in fact, the same based on the SMB protocol, and the version has been upgraded to 3.x.

05

Theoretically, for newer devices, newer versions of operating systems, even with the SMB protocol, should not be affected. What do you mean? The NAS at home and the server at work are old and probably only use SM1.0. Don’t worry, Microsoft said that users who have enabled SMB 1.0 are not affected by these updates, so we just need to click the Win button before upgrading, type “Windows Features”, enter the relevant interface and enable SMB 1.0 will be fine.
