Fix You Ll Need A New App To Open This Ms Windows Store Error In Windows

Work your way through the list of solutions below, and in most cases, you should be able to fix the error relatively quickly.

Restart Your Computer

If the Microsoft Store worked correctly just a moment ago, you’re likely dealing with a minor technical glitch. Restarting your computer should help eliminate it, so try that before diving into the remaining fixes.

Reset Microsoft Store Cache

The Microsoft Store speeds things up by creating temporary files and saving online content locally. However, an outdated cache can prevent it from functioning normally. Try deleting it.

1. Press Windows + X to open the Power User Menu. 
2. Select Windows PowerShell (Admin).
3. Type wsreset.exe into the Windows PowerShell console and press Enter:
4. Once Windows PowerShell finishes clearing the Microsoft Store cache, the Microsoft Store should open automatically.
5. If the “You’ll need a new app to open this ms-windows-store” error shows up instead, exit Windows PowerShell and move onto the next fix.

Reset the Microsoft Store

Resetting the Microsoft Store allows you to revert the program to its defaults. You can do that using Windows 10’s Settings app.

1. Open the Start menu and type Settings and select the Settings App > Apps > Apps & features.
2. Scroll down and select Microsoft Store > Advanced Options.
3. Scroll down to Reset > Click Reset.
4. Wait until the Settings app finishes resetting the Microsoft Store.
5. Open the Microsoft Store. If it opens without issue, you’ll likely have to sign back into it with your Microsoft Account.
