There are many small partners who like to try the early Win11 preview version, and recently someone found a problem, which is less SMB protocol in the home preview version. For most friends, this name is so strange, what is its use? What if it needs to be streamlined? Let's talk today.
SMB, whose full name is Server Message Block, is a protocol developed by Microsoft and Intel in 1987, primarily as a communication protocol for Microsoft networks. As you can see from the current Windows settings interface, it is now mainly used as a file sharing service.
There are many applications, such as data transfer between Windows PCs can use the SMB protocol, and other platforms, such as Android systems, as long as the installation of applications that support the protocol can be cross-platform access, which is more than that, in fact, Unix and other systems, including the native Unix dual system, can share files through this protocol.
Why are such useful features being streamlined? The reasons should be multifaceted, such as looking at the release time, you will find that it is really old, so the security is really a bit worrying, and the high-end network capabilities and security capabilities of the Windows Home Edition are slightly inferior to the professional version, so Microsoft should think that this feature is not important to the Home Edition first, and secondly more insecure.
So, if SMB is disabled, what is the impact? Here we have to explain first, the disabled is SMB 1.0, its problem has long existed, from the Win10 era is not enabled by default, and the default SMB direct connection function, in fact, is also based on the SMB protocol, and the version has risen to 3.x.
Theoretically, for newer devices, newer versions of the operating system, even if the SMB protocol is used, should not be affected. What do you say? The NAS and company's servers at home are very old, and they can 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 key before upgrading, enter "Windows Features", and enable SMB 1.0 after entering the relevant interface.
