 <h2>Invoke-DiskCleanupScan.ps1</h2>
 `Invoke-DiskCleanupScan.ps1` is a PowerShell script for recovering disk space on Windows Server 2016 through current versions. It performs a full scan of the C: drive across all known bloat sources, presents a grouped findings report with sizes, then requires explicit user confirmation before touching anything.
