Liste d'éléments concernant les utilisateurs sur un serveur RDS

$utilisateurListe = Get-ChildItem -Path Registry::HKEY_USERS\ | Where-Object {$_.Name -match '^HKEY_USERS\\S-1-5-21-[\d\-]+$'}

foreach ($utilisateur in $utilisateurListe) {
    $chemin = Join-Path $utilisateur.PSPath "Software\FSLogix\Profiles\Session"
    $element = Get-ItemProperty -Path $chemin 
    Write-Host $utilisateur, $element.ProfilePath, $element.LocalProfilePath
    }

Création de plusieurs clés

Exemple 1

$racine = "S-1-5-21-1234567890-123456789-123456789-"
$liste = Get-ChildItem -Path Registry::HKEY_USERS\ | Where-Object {$_.Name -match "$racine\d{4}$"}

foreach ($compte in $liste) {
    $branche = "Registry::\$compte\Volatile Environment\"

    ## Affichage de la valeur de la clé "USERNAME"
    (Get-ItemProperty -Path $branche -Name USERNAME).username

    ## Création d'éléments
    New-ItemProperty -Path $branche -Name "test"             -PropertyType String -Value "Alphorm"
    New-ItemProperty -Path $branche -Name "HomepageLocation" -PropertyType String -Value "http://phpage.fr"
}

Exemple 2

#HKEY_USERS\S-1-5-21-1234567890-1234567890-123456789-1234 C:\Users\dm C:\Users\local_dm
#HKEY_USERS\S-1-5-21-1234567890-1234567890-123456789-1248 C:\Users\adminphp C:\Users\local_adminphp

$racine = "S-1-5-21-1234567890-1234567890-123456789"
$liste = Get-ChildItem -Path Registry::HKEY_USERS\ | Where-Object {$_.Name -match "$racine-\d{4}$"}
$compte = "$racine-1248"


#foreach ($compte in $liste) {
    $branche = "Registry::HKEY_USERS\$compte"

    ## Affichage de la valeur de la clé "USERNAME"
    (Get-ItemProperty -Path $branche -Name USERNAME).username
    Get-ItemProperty -Path "$branche\Control Panel\Desktop" -Name UserPreferencesMask
    Get-ItemProperty -Path "$branche\Control Panel\Desktop" -Name DragFullWindows
    Get-ItemProperty -Path "$branche\Control Panel\Desktop" -Name FontSmoothing
    Get-ItemProperty -Path "$branche\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize" -Name EnableTransparency
    
    ## test de présence de la clé ; si non présence alors création
    $valeurs = Get-ItemProperty -path "$branche\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced"
    if ($valeurs.PSObject.Properties.Name  -notcontains "TaskbarGlomLevel") {
        New-ItemProperty -Path "$branche\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" -Name "TaskbarGlomLevel" -PropertyType DWord -Value "1"
    }
    
    #Get-ItemProperty -Path "$branche\Control Panel\Desktop\WindowMetrics" -Name MinAnimate
       
    ## Création d'éléments
    #New-ItemProperty -Path $branche -Name "test"             -PropertyType String -Value "Alphorm"
    #New-ItemProperty -Path $branche -Name "HomepageLocation" -PropertyType String -Value "http://phpage.fr"
    
    ## Modification de valeur d'élément
    Set-ItemProperty -Path "$branche\Control Panel\Desktop" -Name DragFullWindows -Value "0"
    Set-ItemProperty -Path "$branche\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize" -Name EnableTransparency -Value "0"
    #Set-ItemProperty -Path "$branche\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced" -Name TaskbarGlomLevel -value
