Ensure 'Create permanent shared objects' is set to 'No One'

HighLevel 1Automatedwindows

Description

This user right is useful to kernel-mode components that extend the object namespace. However, components that run in kernel mode have this user right inherently. Therefore, it is typically not necessary to specifically assign this user right. The recommended state for this setting is: No One.

$f = Join-Path $env:TEMP ('tmaegis-' + [guid]::NewGuid().ToString() + '.inf'); secedit /export /cfg $f /areas SECURITYPOLICY USER_RIGHTS /quiet | Out-Null; $c = Get-Content $f -ErrorAction SilentlyContinue; Remove-Item $f -Force -ErrorAction SilentlyContinue; $line = $c | Where-Object { $_ -match '^\s*SeCreatePermanentPrivilege\s*=' } | Select-Object -First 1; $v = if ($line) { ($line -split '=', 2)[1].Trim().Trim('"') } else { $null }; $have = @(if ($v) { $v -split ',' | ForEach-Object { $_.Trim().TrimStart('*') } | Where-Object { $_ } }); if ((($have | Sort-Object -Unique) -join ',') -eq '') { 'compliant' } else { 'non-compliant: ' + ($have -join ',') }

Expected output: compliant
