Run SFC to fix corrupted system files by opening Command Prompt as Administrator and typing sfc /scannow, then restart; 2. Use DISM with commands DISM /Online /Cleanup-Image /CheckHealth, /ScanHealth, and /RestoreHealth to repair the system image; 3.

The UNEXPECTED_STORE_EXCEPTION Blue Screen of Death (BSoD) in Windows typically points to issues with the Client Server Runtime Process (csrss.exe) or problems in the Windows Store-related services and system files. While it might seem related to apps from the Microsoft Store, it’s often caused by deeper system-level corruption, driver conflicts, or faulty updates.

Here’s how to fix it — in order from most effective and common to more advanced:

1. Run System File Checker (SFC)

Corrupted system files are a leading cause of this error.

Steps:

• Open Command Prompt as Administrator.
• Type:

  sfc /scannow

• Wait for the scan to complete (can take 15–30 minutes).
• If issues are found and repaired, restart your PC and check if the BSoD returns.

If SFC fails or can’t fix everything, move to DISM.

2. Use DISM to Repair the System Image

DISM fixes the underlying Windows image that SFC relies on.

Steps:

• In the same Admin Command Prompt:

  DISM /Online /Cleanup-Image /CheckHealth

  Then:

  DISM /Online /Cleanup-Image /ScanHealth

  And finally (if needed):

  DISM /Online /Cleanup-Image /RestoreHealth

• Wait for the process to finish (may take 10–20 minutes).
• Restart and test.

3. Update or Roll Back Drivers

Faulty or outdated drivers — especially storage, GPU, or chipset drivers — can trigger this error.

What to do:

• Press Win X → Device Manager.
• Look for drivers with a yellow warning icon.
• Right-click and Update driver.
• Pay special attention to:
  • Display adapters
  • Storage controllers (especially NVMe or SATA)
  • System devices (like Intel Management Engine)

If the BSoD started after a recent driver update, roll it back:

• Right-click the driver → Properties → Driver tab → Roll Back Driver.

Alternatively, download the latest drivers from your PC or motherboard manufacturer’s website.

4. Disable or Reset Microsoft Store Cache

Since the error references "Store," a corrupted Store cache might be involved.

Clear the Store cache:

• Press Win R, type:

  wsreset.exe

• Press Enter. A black window will appear briefly, then the Microsoft Store opens.
• Restart your PC afterward.

If that doesn’t help, reset the Store:

• Go to Settings > Apps > Apps & features.
• Find Microsoft Store.
• Click it → Advanced options → Repair, then Reset.

5. Check for Windows Updates

Microsoft often releases patches for known BSoD issues.

• Go to Settings > Update & Security > Windows Update.
• Install all pending updates.
• If the issue started after an update, consider uninstalling it:
  • Go to Update history → Uninstall updates → remove the most recent quality or feature update.

6. Scan for Memory and Disk Issues

Hardware problems can mimic system errors.

Run Windows Memory Diagnostic:

• Search for Windows Memory Diagnostic.
• Choose Restart now and check for problems.
• Let it run — if errors are found, you may have failing RAM.

Check disk health:

• Open Command Prompt (Admin) and run:

  chkdsk /f /r

• It will ask to schedule on next reboot — type Y, then restart.

7. Perform a Clean Boot (Identify Software Conflicts)

Third-party services or startup apps might interfere with system processes.

Steps:

• Press Win R, type msconfig, hit Enter.
• Go to Services tab → check Hide all Microsoft services → click Disable all.
• Go to Startup tab → Open Task Manager → disable all startup items.
• Restart.

If the BSoD stops, re-enable services/startup apps in batches to find the culprit.

8. Consider a System Restore or Reset

If the issue persists and you have a restore point from before the BSoD started:

• Use System Restore to revert system files and settings.
• Or, as a last resort:
  • Go to Settings > Update & Security > Recovery.
  • Choose Reset this PC → Keep my files (recommended first step).

This reinstalls Windows without deleting personal files.

Bottom line:
Start with SFC and DISM, then tackle drivers and updates. The UNEXPECTED_STORE_EXCEPTION is rarely about the Store app itself — it’s usually deeper system corruption or hardware issues. Most cases are resolved with file repairs and driver updates.

Basically, it’s not as scary as it looks — but don’t ignore it.
