Softwarekatalog

Windows self-service software catalog backed by winget.

Users install approved software through a small GUI or request helper. A SYSTEM scheduled task runs a named-pipe daemon, authenticates the connecting Windows user, validates requests against Group Policy, then runs winget install --scope machine.

What It Does

• Reads allowed software from GPO registry policy.
• Lets users install/uninstall only catalog entries allowed by policy.
• Installs required software automatically.
• Runs winget upgrade --all every 2 hours.
• Tracks installed state from winget export, not from request history.

Policy

ADMX templates live in PolicyDefinitions/.

Copy them to your domain Central Store:

\\<domain>\SYSVOL\<domain>\Policies\PolicyDefinitions\Softwarekatalog.admx
\\<domain>\SYSVOL\<domain>\Policies\PolicyDefinitions\de-DE\Softwarekatalog.adml
\\<domain>\SYSVOL\<domain>\Policies\PolicyDefinitions\en-US\Softwarekatalog.adml

Policy registry path:

HKLM\Software\Policies\STL\Softwarekatalog

Catalog entries:

HKLM\Software\Policies\STL\Softwarekatalog\Catalog
alias = PackageId|DisplayName|Description

Required software:

HKLM\Software\Policies\STL\Softwarekatalog\Required
alias = 1

The client reads up to 500 catalog entries and 500 required entries.

Install

Build the ASCII-only distribution wrapper:

make dist

Use dist/setup.ps1 for deployment. It is ASCII-only and decodes the UTF-8 payload at runtime, avoiding Windows PowerShell 5.1 encoding issues with downloaded scripts.

Run as admin or as computer startup script:

powershell.exe -NoProfile -ExecutionPolicy Bypass -File .\dist\setup.ps1 -Mode Install

Generated files are written to:

C:\ProgramData\__Softwarekatalog\

Notes

• Requires Windows, Desktop App Installer, and winget.
• The daemon runs as LocalSystem; keep catalog policy restricted to trusted admins.
• Package IDs and silent machine-scope support depend on upstream winget packages.
