+# 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:
+
+```text
+\\<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:
+
+```text
+HKLM\Software\Policies\STL\Softwarekatalog
+```
+
+Catalog entries:
+
+```text
+HKLM\Software\Policies\STL\Softwarekatalog\Catalog
+alias = PackageId|DisplayName|Description
+```
+
+Required software:
+
+```text
+HKLM\Software\Policies\STL\Softwarekatalog\Required
+alias = 1
+```
+
+The client reads up to 500 catalog entries and 500 required entries.
+
+## Install
+
+Run as admin or as computer startup script:
+
+```powershell
+powershell.exe -NoProfile -ExecutionPolicy Bypass -File .\setup.ps1 -Mode Install
+```
+
+Generated files are written to:
+
+```text
+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.
