Solved Answer

The Microsoft Store is a digital marketplace that allows users to browse and download apps, games, and media content for Windows, Xbox, and Surface devices. It provides a central location for users to find and download the latest software – they don't need to visit other – possibly dangerous places – to do so.

Despite its usefulness, it may sometimes malfunction, and the most common issues related to it are download and installation errors, such as 0x803fb107. This particular error has been around for years, and users are still looking for answers to this day. Luckily, there are several ways to fix it, and you have come to the right place if you want to deal with it once and for all.

0x803fb107 is a Microsoft Store error that can occur whenever users attempt to download or update already installed apps. It can also show up whenever players are trying to download games from the Windows Xbox app. In this case, the problem appears in both Microsoft Store and Xbox apps.

Microsoft Store app installation errors can occur due to various reasons, including bugged caches, related services not being configured properly, account issues, corrupted system files, and much more.

Fix 4. Check for corrupted system files

You can repair damaged system files by running commands via Command Prompt:

• Type cmd in Windows search.
• Right-click on the Command Prompt result and select Run as administrator.
• User Account Control (UAC) window will ask whether you want to allow changes to your computer – click Yes.

  sfc /scannow
  DISM /Online /Cleanup-Image /CheckHealth
  DISM /Online /Cleanup-Image /ScanHealth

Fix 5. Reregister the app via PowerShell

• if the service is not running, double-click it, and pick Automatic under the Startup type from the drop-down menu.

Fix 7. Reinstall Windows

There are several ways you can do this, but we recommend using Media Creation Tool, which would download and install files from Microsoft Server directly. Before proceeding, disable or uninstall third-party security software and disconnect any unnecessary peripherals, such as printers. Also, for the best result, we recommend copying all personal files from the main drive and wiping them all instead of keeping them.

• Visit the official Microsoft website and download Windows 10 installation media (Windows 11 version).
• Double-click the installer and select Yes when the User Account Control (UAC) prompt appears.
• Agree to the terms and conditions.
• Select the Create installation media (USB flash drive, DVD, or ISO file) for another PC option and click Next.
• Check the Use recommended options for this PC checkbox and click Next.
• Choose the ISO file option and click Next.

• Once the ISO file is prepared, insert it into the malfunctioning PC.
• Restart the machine and press F8, F10, F12, Del, or another button that will take you to the BIOS.
• In the BIOS, go to the Boot section and set the boot priority to Flash drive.
• Restart the system.
• When prompted, pick the Delete everything option.
