How to find out what version of SMB is installed on windows 7

Question

I am using Windows 7 and want to find out if SMB is installed and if so what version. How can I do this?

I found this article but it doesn't seem to return anything: https://support.microsoft.com/en-gb/help/2696547/how-to-detect-enable-and-disable-smbv1-smbv2-and-smbv3-in-windows-and

I have ran the following commands in Powershell as described in the article and have done it for SMB1 and also tried changing it to SMB2

Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters" SMB1 -Type DWORD -Value 1 –Force

Entries have been created in regedit:

but when I run this command which is meant to detect a version it just returns nothing and just moves to another line in the powershell window:

Get-ChildItem HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\Parameters | ForEach-Object {Get-ItemProperty $_.pspath}

If the reason it is not showing is because it is not installed then how can I install it for windows 7?

Thanks

Answer 1

SMB is a protocol for file sharing. This is a Microsoft protocol, the windows SMB version number is not what you are looking for, what you are looking for is the features that your SMB version is supporting. On your platform (win 7), SMB3 is not supported (one of the main features is encryption).

About other machines there are several companies that implements this protocol, (SAMBA, visuality Systems, ryussi etc.) and in their services you can look for the version.

Answer 2

Try this instead:

Get-ChildItem HKLM:\SYSTEM\CurrentControlSet\Services\LanmanServer\ | ? 
{$_.Name -like "*Para*"}

That should output the values for SMB1 and SMB2 which you are setting with the Set-ItemProperty .
