Every Windows user has their favorite app, but the Microsoft Store should be at the top of that list because you may not be able to download other apps without it. Granted, you can still sideload apps on your Windows 11, but this comes at a risk.

Apps downloaded from the Microsoft Store have passed rigorous checks that ensure they are safe. However, the error 0x80004003 can be frustrating, as it prevents users from downloading apps. If you’ve encountered this error, we share how to bypass it in this article.

What does this error code mean, 0x80004003?

The 0x80004003 error code occurs when users try to launch the Microsoft Store application on their Windows PCs. It may be triggered by one or more of the following reasons:

  • Corrupt update – If you’ve recently updated your OS, it is possible one of the installation files had an issue stopping Microsoft Store from working.
  • Bugs in the app  – It is also possible that the Microsoft Store has somehow ended up with a bug. This could be through Windows updates or in-app updates.
  • Cache build-up –  If you’ve been using the Microsoft Store for a while, too much cache may prevent you from launching the app.

How do I fix error code 0x80004003?

Before any complex solutions, try the following basic checks first:

  • First, ensure you’re using a legitimate copy of Windows and that it is activated. Pirated copies don’t usually get regular updates and may not function as well as the original version.
  • Check for any Windows updates and download and install if available.
  • Roll back a previous Windows update, especially if this issue began after updating.
  • Uninstall any recently installed app that may be conflicting with the Microsoft Store.
  • Restart your PC to eliminate any temporary files that may prevent Microsoft Store from launching.
