App Fetch

Install UWP apps without the Microsoft Store.

App Fetch

The Microsoft Store is removed in JarvisOS. App Fetch is its replacement — a clean, telemetry-free tool for sideloading UWP (Universal Windows Platform) applications directly from their source.

JarvisOS installs App Fetch automatically as part of the maintenance tools suite.

What It Does

App Fetch hooks into Windows’ native Appx deployment APIs to install .appxbundle and .msixbundle packages directly, without routing through Microsoft’s Store infrastructure or its associated telemetry endpoints.

It handles:

• Cryptographic signature verification
• Dependency resolution (VCLibs, .NET Native frameworks)
• Silent background installation
• Local package caching

---

Basic Usage

app-fetch install <PackageID_or_URL>

Run as Administrator from an elevated terminal.

---

Examples

From a URL

Install directly from a GitHub release or any direct download link.

app-fetch install https://github.com/user/repo/releases/latest/download/app.msixbundle

From a local file

Sideload a package you already have downloaded.

app-fetch install C:\Downloads\Terminal.appxbundle

Re-deploy Store

If you specifically need the Microsoft Store for a workflow that has no alternative:

app-fetch deploy --target ms-store

---

Dependency Cache

App Fetch maintains a local cache of framework dependencies at %PROGRAMDATA%\AppFetch\Cache to avoid re-downloading on subsequent installs.

Clear the cache:

app-fetch clean --cache

Recommended Alternatives to Store Apps

Store App	Replacement
Edge	Brave / LibreWolf / Ungoogled Chromium
Microsoft Photos	IrfanView / nomacs
Microsoft Media Player	mpv / VLC
Microsoft To Do	Obsidian / Logseq
Office Online	OnlyOffice (already installed by JarvisOS)

For most developer tools, prefer WinGet or Chocolatey over App Fetch. App Fetch is specifically designed for UWP/MSIX packages that are not available via those package managers.

# WinGet is preserved and ready to use
winget install <PackageName>

# Chocolatey (install separately)
choco install <PackageName>
