InstallerClean v1.0.0

Safely clean up C:\Windows\Installer, the hidden Windows folder that quietly eats your disk space.

Downloads

• InstallerClean.exe (162 MB) - works on any Windows 10/11 machine, nothing else needed
• InstallerClean-framework-dependent.exe (8 MB) - if you already have .NET 8 Desktop Runtime installed

Just download and run. No installer, no account, no data collection.

What it does

• Scans C:\Windows\Installer for orphaned .msi and .msp files
• Detects superseded patches (especially useful for Adobe Acrobat)
• Delete to Recycle Bin or move to a folder you choose
• CLI mode (/d, /m, /m PATH) for scripting and automation
