The user is unable to log into the Microsoft Store on a Windows 11 desktop because the authentication screen turns completely blank immediately after entering a PIN.

How to Fix Microsoft Store Login Screen Going Blank After PIN Entry

Product: Microsoft Store
Device & OS: Windows 11
Scenario: Attempting to sign in to the Microsoft Store application using a user profile and a security PIN.
Observed behavior: The login window goes blank after the PIN is entered, preventing access. Web sign-in works normally, and standard resets or reinstalls of the Store application fail to resolve the glitch.

Before you start

Ensure your computer is connected to a stable network and save any open work before modifying system services or restarting your desktop.

Solution 1Recommended

Change Windows Display Language

Temporarily changing the display language forces Windows to refresh regional profiles and UI elements, which resolves this specific Store authentication glitch.

While it may seem unrelated, a known glitch between the Microsoft Store UI and Windows regional settings can cause blank authentication screens. Refreshing the language parameters effectively bypasses the bug.

Open Language Settings

Click the Start button, select Settings, and navigate to Time & language > Language & region.

Change the Display Language

Under 'Windows display language', click the dropdown and select a different language (e.g., English UK if you are on English US). If you don't have another language installed, click 'Add a language' first.

Restart and Test

Sign out and sign back in (or restart your PC) to apply the language change. Open the Microsoft Store and attempt to sign in with your PIN again. Once successful, you can switch your display language back to your preferred default.

Confirmed Fix: This method has been confirmed by users to resolve the blank PIN screen when standard application resets fail.

Solution 2

Enable Microsoft Account Sign-in Assistant

Ensuring the background service responsible for Microsoft account authentication is running automatically.

Solution 3

Test with a New Local User Profile

Create a new user account to determine if the blank screen issue is caused by a corrupted Windows profile.

Frequently Asked Questions

Why does the Microsoft Store screen go blank immediately after entering a PIN?

This blank screen glitch often occurs due to desynchronization in Windows display language settings, a stopped Microsoft Account Sign-in Assistant service, or a locally corrupted user profile cache on Windows 11.

Will resetting the Microsoft Store using WSReset.exe fix this login error?

While the WSReset.exe command clears the store cache and fixes many download issues, users frequently report that it does not resolve this specific blank screen upon PIN entry. Altering regional language settings is a more effective fix for this bug.

Does this Store login issue affect my ability to use web sign-in?

No. This issue is isolated to the local Microsoft Store application and its authentication UI prompt. Web sign-in for your Microsoft account through browsers like Edge or Chrome will continue to work normally.

How can I easily check if my Windows profile is causing the Microsoft Store glitch?

You can diagnose profile corruption by navigating to Settings > Accounts > Other users, creating a temporary new local account, and attempting to log into the Store from that fresh environment.
