Operating systems don’t always work the way you want them to, including Windows. They are prone to all sorts of software and hardware issues, often resulting in Blue Screen of Death errors that take up the entire screen and prevent you from doing anything on your PC.

However, there’s no need to panic. Blue screen messages are accompanied by stop codes that you can look up online to find easy solutions. It’s probably how you ended up on this page when researching UNEXPECTED STORE EXCEPTION.



UNEXPECTED STORE EXCEPTION is a Blue Screen of Death error that occurs on Windows 10 and older versions. It cripples your computer and prevents you from using it for work or play.

The stop code is typically triggered by hardware failure. It means that, to get rid of the error message, it’s necessary to identify and troubleshoot the underlying hardware issue.

It could be one or several problems. Some users have reported that no minidumps are created after their PC crashes.


You don’t need to turn to a computer specialist for help or to start learning PC troubleshooting. As long as you follow the instructions below, you should be able to resolve the UNEXPECTED STORE EXCEPTION error in no time.

However, we recommend creating a system restore point on your Windows 10 PC before trying a new solution. It gives you the possibility to undo any software changes you make, in case you accidentally do more damage than good.

1. Free up your disk space

Insufficient disk space could be the reason behind the UNEXPECTED STORE EXCEPTION stop code. If you often get notified by Windows 10 about running low on disk space, then you can fix it by making more room on your hard drive.

Make sure to move your large files to an external hard disk, including videos, movies, and even installed games. Furthermore, you should uninstall the big applications that you don’t use anymore.

When it comes to junk files, you can turn to a system cleaner or just use Microsoft’s integrated Disk Cleanup utility. Before using it, you should check the Downloads folder and Recycle Bin to see if there are any files you want to back up or restore.

How to use Disk Cleanup:

  1. Make sure you’re logged in as the computer administrator
  2. Press Win + E to open the file explorer, right-click the drive where Windows is installed, and open PropertiesWindows Explorer shows how to access the Properties of the C: drive
  3. In the General tab, click Disk CleanupWindows 10 shows how to perform Disk Cleanup on the C: drive
  4. Check all items in the Files to delete area and click Clean up system filesWindows 10 shows how to select files for Disk Cleanup

But if you don’t want to risk getting the wrong driver for your operating system and architecture type, it’s better to use a driver updating tool.

It also helps with updating multiple drivers at the same time. You just have to launch the tool. It will scan your computer for all old drivers and download more recent versions from the web.

4. Check your RAM

Your computer might be experiencing issues with the RAM card, which could result in various hardware problems, including the UNEXPECTED STORE EXCEPTION error code.
