How To Fix the “You’ll Need a New App to Open This MS-Windows-Store” Error in Windows

Encountering the error “You will need a new app to open this MS-Windows-Store” when trying to install or open apps from the Microsoft Store can be super frustrating. Sometimes, it’s just a weird glitch, other times it’s something more stubborn like corrupt cache, broken user profiles, or issues after a Windows update. Fixing it isn’t always obvious, but there are a few tried-and-true methods that can help get the Store working again without a complete OS reinstall. These fixes range from simply rebooting to more involved tricks like re-registering apps or clearing cache. Often, a combination of these steps is needed, especially if the error hangs around after updates or system changes. So, if the usual “restart and hope for the best” isn’t helping, let’s dig into what might actually fix this mess and get your Store back on track.

How to Fix the “You’ll Need a New App to Open This MS-Windows-Store” Error in Windows

Reset the Store Cache with wsreset.exe

This is kind of a classic move for Store issues. The cache files can go bad, leading to weird errors like this. Resetting cache via wsreset.exe is quick and often fixes the problem on the spot. It clears out corrupted cache files that might be interfering with app installation or opening.

  1. Press the Windows key and type wsreset.exe.
  2. Click on the wsreset.exe app that appears — no need to run it as admin, just click it.
  3. A blank command prompt window will pop up, and then your Store should automatically open once the reset is done.

If the Store doesn’t launch or the error persists, no worries — it’s time for more fixes.

Re-register the Microsoft Store with PowerShell

Sometimes, the Store app itself gets entities messed up—like its registration or files. Re-registering essentially reinstalls the Store without needing to reinstall Windows. Not sure why it works, but on my setup, doing this fixed issues after some Windows updates that broke the Store.

  1. Right-click the Start menu or press Windows + X and select Windows PowerShell (Admin).
  2. Copy and paste this command, then hit Enter:
    3. Get-AppXPackage *Microsoft. WindowsStore* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_. InstallLocation)\AppXManifest.xml"}
  3. Wait for it to finish—it might take a minute or two, so be patient. Once done, restart your PC and see if the Store works.

This process re-establishes the Store’s registration files, which can fix the crazy errors.

Check System Files with SFC and DISM

If core system files are corrupted, that might mess up the Store too. Running sfc /scannow and DISM /Online /Cleanup-Image /RestoreHealth can repair missing or damaged Windows files without a complete reinstall.

  1. Open PowerShell as administrator.
  2. Type sfc /scannow and hit Enter. Wait for it to scan and fix bad system files.
  3. If issues still persist, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
  4. Once complete, restart your PC and check the Store again.

Ensure Windows and Apps are Up to Date

It’s weird but sometimes, bugs are fixed in patches. If your Windows is running outdated, the Store may behave funny or throw errors like this. Check for updates and install anything pending.

  1. Open Settings (Windows + I), go to Windows Update.
  2. Click Check for updates and install any available updates.
  3. After updates, reboot and try the Store again.

Sometimes, even uninstalling recent updates that caused problems helps — especially if errors pop up after a Windows update.

Other Tricks and Tools

If none of the above work, you can try using the built-in troubleshooter for Windows Store apps. It does its best to identify and fix issues automatically. Also, resetting or repairing the Store from Apps & Features in Settings can sometimes do the trick.

Another trick? Reinstalling the Store’s package via PowerShell commands with an elevated session, or even using advanced scripts like those available on repositories such as the GitHub: Winhance. Just be careful with these, and always back up your data first.

Final Resort: Reinstall All Microsoft Store Apps

If all else fails, you can try to force-reinstall and re-register *all* built-in apps, including the Store, by running this command in PowerShell opened as admin:

Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_. InstallLocation)\AppXManifest.xml"}

This tends to reset everything back to default, but it can take a few minutes. Afterward, restart and see if the Store and other apps behave better.

Summary

  • Reset Store cache with wsreset.exe
  • Re-register the Store using PowerShell commands
  • Check and repair system files with SFC and DISM
  • Update Windows and uninstall recent updates if needed
  • Use troubleshooter for Windows Store apps
  • Reinstall or reset all Store apps as last-ditch effort

Wrap-up

Dealing with Store errors can be a pain, but most problems are fixable with a few tweaks—nothing too wild. Sometimes, it’s just a corrupted cache or a goofy system file. Hopefully, one of these methods helps. On one machine, resetting the cache did the trick; on another, re-registering the app worked after a reboot. Just keep trying if the first thing doesn’t work. Good luck fixing that error — fingers crossed this helps someone out there!
