Computer inventory from Active Directory | PowerShell script | Windows versions, end of support, LAPS | HTML report + CSV | German

A PowerShell script that lists all computer accounts in an Active Directory – operating system, version, end of support, last login, LAPS – and checks for anomalies in 12 criteria. The result: a clear HTML report in German and, optionally, the inventory as a CSV file for Excel.

THIS IS INCLUDED
• PowerShell script Computer Inventory.ps1 (source code open and commented)
• Instructions as PDF
• Sample report of a test domain (HTML)

THE SCRIPT ONLY WORKS IN READING TIME
It makes no changes to Active Directory, does not query the computers themselves, and does not transfer any data. A normal domain account is sufficient; administrator rights are not required.

THE 12 CHECKPOINTS
• Operating system: Operating system is no longer supported; support ends in the coming months; operating system not rated (not in the support table); evaluation versions
• Computer accounts: Active accounts without login for X days; Disabled computer accounts; Computers in the default "Computers" container; Computers without a LAPS password; LAPS password expired more than 30 days ago; Old account password despite current login; Computers added by regular users; Any user is allowed to add computers to the domain

REQUIREMENTS
• Windows PowerShell 5.1
• PowerShell module ActiveDirectory (present on domain controllers, otherwise RSAT)
• Tested with Windows PowerShell 5.1 on Windows Server 2025 in a test domain with approximately 20 computer accounts, as administrator and as a regular user; each checkpoint was triggered with a simulated scenario. Very large directories (many thousands of computers) and the legacy LAPS were not tested.

FOR WHOM
Administrators and IT service providers who want to know which computers are in the domain, which Windows versions are expiring, and which accounts can be cleaned up.
