powershell - list local users and their groups

问题

I'd like to have a report with all the local users and their relative groups (users, power users, administrators and so on.

I get the users in this way:

$adsi = [ADSI]"WinNT://."
$adsi.psbase.children | where {$_.psbase.schemaClassName -match "user"} | select @{n="Name";e={$_.name}}

but I don't know how to retrieve their groups. Thanks in advance.

回答1:

$adsi = [ADSI]"WinNT://$env:COMPUTERNAME"
$adsi.Children | where {$_.SchemaClassName -eq 'user'} | Foreach-Object {
    $groups = $_.Groups() | Foreach-Object {$_.GetType().InvokeMember("Name", 'GetProperty', $null, $_, $null)}
    $_ | Select-Object @{n='UserName';e={$_.Name}},@{n='Groups';e={$groups -join ';'}}
}

For Googlers, another way to get a list of users is to use:

Get-WmiObject -Class Win32_UserAccount

Update as an alternative to the excellent answer from 2010:

You can now use the Get-LocalGroupMember, Get-LocalGroup, Get-LocalUser etc. to get and map users and groups

Example:

PS C:\WINDOWS\system32> Get-LocalGroupMember -name users

ObjectClass Name                             PrincipalSource 
----------- ----                             --------------- 
User        DESKTOP-R05QDNL\someUser1        Local           
User        DESKTOP-R05QDNL\someUser2        MicrosoftAccount
Group       NT AUTHORITY\INTERACTIVE         Unknown  

You could combine that with Get-LocalUser. Alias glu can also be used instead. Aliases exists for the majority of the new cmndlets.

In case some are wondering (I know you didn't ask about this) Adding users could be for example done like so:

$description = "Netshare user"
$userName = "Test User"
$user = "test.user"
$pwd = "pwd123"

New-LocalUser $user -Password (ConvertTo-SecureString $pwd -AsPlainText -Force) -FullName $userName -Description $description

Expanding on mjswensen's answer, the command without the filter could take minutes, but the filtered command is almost instant.

PowerShell - List local user accounts

Fast way

Get-WmiObject -Class Win32_UserAccount -Filter  "LocalAccount='True'" | select name, fullname

Slow way

Get-WmiObject -Class Win32_UserAccount |? {$_.localaccount -eq $true} | select name, fullname
