You can also open the “Device Manager” through the “Run” dialog, by pressing the ⊞ Win + R and executing the devmgmt.msc command.
Although there is no direct equivalent to the lsusb command in Windows, you can use the PowerShell’s Get-PnpDevice command to list the connected USB devices and display the information about them. (more…)
Get-ADGroupMember command in a Windows PowerShell is used to get the members of an Active Directory (AD) group.

To get the members of an AD group in the domain the computer is connected to, use the PowerShell’s Get-ADGroupMember command as follows:
PS C:\> Get-ADGroupMember -Identity "<groupName>"
If the AD group which members you need to get is in another domain, add the Server parameter:
PS C:\> Get-ADGroupMember -Identity "<groupName>" -Server <domain>
To get the sorted list of the AD group member names only:
PS C:\> Get-ADGroupMember -Identity "<groupName>" | Select Name | Sort Name
To extract the every member of the “nested” AD group (when another groups are among the group members), add the Recursive attribute:
PS C:\> Get-ADGroupMember -Identity "<groupName>" -Recursive | Select Name | Sort Name
If you are getting an error as follows while trying to execute the commands above, you need to install the Active Directory Users and Computers on your computer:
Get-ADGroupMember : The term ‘Get-ADGroupMember’ is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

To get all the Active Directory groups in the domain the computer is connected to, use the PowerShell’s Get-ADGroup command as follows:
PS C:\> Get-ADGroup -Filter *
To get the Active Directory groups in another domain, add the Server parameter:
PS C:\> Get-ADGroup -Filter * -Server <domain>
To get the sorted list of the Active Directory group names only:
PS C:\> Get-ADGroup -Filter * | Select Name | Sort Name
Use the following construction to search for the Active Directory groups using the PowerShell’s grep equivalent, e.g. to get the Active Directory group names starting with “Adm“):
PS C:\> Get-ADGroup -Filter * | Select Name | Out-String -Stream | Select-String "^Adm.*"
To find a single group, use the Identity parameter, e.g. to check if an Active Directory group called ‘Administrators‘ exists, run the command below:
PS C:\> Get-ADGroup -Identity 'Administrators'
If you are getting an error as follows while trying to execute the commands above, you need to install the Active Directory Users and Computers on your computer:
