But before you throw in the towel and call tech support, there are numerous solutions you can try that often resolve the problem quickly and painlessly.

TL;DR (Too Long; Didn’t Read)

If that doesn’t work, reset the app, re-register it using PowerShell, or update Windows. Try everything in this guide before contacting Microsoft Support—it could save you hours.

Common Causes Behind Microsoft Store Login Issues

Microsoft Store sign-in problems can result from a variety of issues. Some of the most frequently encountered causes include:

  • Incorrect or outdated Microsoft account credentials
  • Corrupted Windows Store cache
  • Incorrect system date and time settings
  • Outdated or corrupted Windows system files
  • Network-related issues
  • Disabled Microsoft services

Understanding these potential causes can help you isolate and fix the root of the issue much faster.

Step-by-Step Solutions To Fix Microsoft Store Login Problems

1. Check Date, Time, and Region Settings

One of the simplest yet most overlooked fixes is ensuring your system’s date, time, and region are set correctly. Incorrect settings can interfere with server communication.

  1. Go to Settings > Time & Language > Date & Time.
  2. Enable Set time automatically and Set time zone automatically.
  3. Click on Region and confirm the correct country is selected.

2. Test Your Internet Connection

A slow or unstable connection can prevent the Microsoft Store from authenticating login credentials. Run a quick speed test or try accessing other online services. You can also:

  1. Restart your router or modem.
  2. Connect to a different Wi-Fi network if available.
  3. Use a wired Ethernet connection for a more stable signal.

3. Sign Out and Back Into Your Microsoft Account

Sometimes, all it takes is a fresh sign-in session. Here’s how:

  1. Open the Microsoft Store app.
  2. Click your profile icon in the top-right corner.
  3. Select Sign out.
  4. Close the app completely, then reopen it and sign back in.

4. Run the Windows Store Apps Troubleshooter

Windows includes a built-in troubleshooter that identifies and fixes store-related problems automatically:

  1. Go to Settings > System > Troubleshoot > Other troubleshooters.
  2. Find Windows Store Apps and click Run.

Follow any prompted instructions and let Windows do its thing.

5. Clear the Microsoft Store Cache

The Windows Store often misbehaves due to corrupted cache files. Thankfully, clearing them is easy:

  1. Press Win + R to open the Run dialog.
  2. Type wsreset.exe and press Enter.

This command will launch a blank Command Prompt window, then automatically restart the Microsoft Store app.

6. Reset the Microsoft Store App

If clearing the cache doesn’t help, try resetting the entire app to its default state:

  1. Go to Settings > Apps > Installed apps.
  2. Find Microsoft Store and click the three-dot menu > Advanced options.
  3. Click Reset and confirm the prompt.

Reopen the Store and sign in again once reset is complete.

7. Re-register the Microsoft Store Via PowerShell

If the app seems unresponsive or buggy, re-registering it might help. Here’s how:

  1. Search for Windows PowerShell in the Start Menu.
  2. Right-click it and select Run as administrator.
  3. Paste the following command and hit Enter:

Get-AppxPackage *WindowsStore* | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppxManifest.xml"}

Once complete, restart your computer and try logging in again.

8. Ensure Essential Services Are Running

Several Windows services need to be running for the Microsoft Store to function properly:

  1. Press Win + R, type services.msc, and press Enter.
  2. Ensure the following services are running:
    • Windows Update
    • Microsoft Account Sign-in Assistant
    • Background Intelligent Transfer Service
  3. If any are not running, right-click and select Start.

9. Update Windows

Outdated system files can cause compatibility issues with Microsoft Store features. To update:

  1. Go to Settings > Windows Update.
  2. Click Check for updates and install any pending updates.

After installing, reboot your PC and test the Microsoft Store login again.

10. Disable Proxy or VPN Services

Proxy servers or VPNs can interfere with the store’s ability to authenticate your login:

  1. Go to Settings > Network & Internet > Proxy.
  2. Set Use a proxy server to Off.
  3. Temporarily disable any VPN software you’re running and try again.

11. Create a New User Profile

Sometimes the issue lies with a corrupted user profile. Try creating a new one:

  1. Go to Settings > Accounts > Family & other users.
  2. Click Add account and follow prompts to create a new user.
  3. Log into the new profile and test Microsoft Store sign-in there.

12. Scan for System Corruption

Corrupted system files can block Store functionality. Use the built-in tools to check:

  1. Open Command Prompt as admin.
  2. Enter sfc /scannow and press Enter.
  3. Once complete, follow it up with:

    Dism /Online /Cleanup-Image /RestoreHealth

Reboot after running both commands and attempt to sign in again.

When to Contact Microsoft Support

If all else fails and you’ve exhausted the above options, it may be time to escalate the issue. Before you contact support, make sure:

  • You’ve tried logging into your Microsoft account on a browser to confirm account validity.
  • You’ve tested login on another Windows device, if available.
  • All services and updates are functional.

Having these steps out of the way will help the support team assist you more efficiently.
