How to fix UNEXPECTED_STORE_EXCEPTION Blue Screen of Death error

The BSOD (Blue Screen of Death) error usually indicates that the computer ran into a problem and needs to restart. There are various BSOD errors that occur after a system crash or fatal system error. A BSOD error states that a problem occurred and that the computer cannot operate properly or safely. Therefore, a BSOD error is also known as a STOP error (it stops the operating system from running). There are different kinds of problems that might cause a BSOD error. In the worst situation, the system might become stuck in an endless loop, continually restarts, never gets to load Windows and displays the same BSOD error.

You may have encountered the UNEXPECTED_STORE_EXCEPTION BSOD error. It is difficult to ascertain exactly what causes this error, since there could be a number of reasons. In many cases, corrupted drivers cause this problem. In other cases, anti-virus software is the cause. This error is often difficult to deal with, since there is no single way to fix it. Fortunately, it is possible to fix the UNEXPECTED_STORE_EXCEPTION BSOD error by trying a number of different methods. This can, however, take some time.

You might need to turn off the Fast Startup feature, disable antivirus software, reset Microsoft Store apps, scan and repair system files by running System File Check (SFC), perform a clean boot, update drivers, and check disk drives for errors. Read the guide below for a possible solution.

NOTE: If you are unable to login to Windows and continually receive the UNEXPECTED_STORE_EXCEPTION error each time you restart the computer, you need to boot Windows into Safe Mode with Networking. If you are not sure how to boot into Safe Mode (or Safe Mode with Networking), read this guide - use the "Interrupt Windows Boot Process" method described at the link. Alternatively, you can use a Windows Installation CD/DVD/USB and boot Windows into Safe Mode with Networking using the Automatic Repair (Advanced Startup) screen. Once you are logged into Windows, apply the methods described below.

Turn off Fast startup feature

First, try to disable the Fast Startup feature. This has helped many people - the UNEXPECTED_STORE_EXCEPTION error disappeared. The Fast Startup feature on Windows 10 (and also Windows 8) provides a faster boot time when starting up the computer. It is a useful feature, and one that most people use without their knowledge, however, some people disable it immediately when they receive a new computer running the Windows operating system. Leaving Fast Startup enabled should not harm your PC, since it is a Windows feature, however, it could be the reason for the BSOD error. To disable Fast Startup, go to Search and type "power". Click on the "Choose power plan" result to open it.

turn off fast startup feature step 1

In the Power Options window, click "Choose what the power buttons do".

turn off fast startup feature step 2

Click on "Change settings that are currently unavailable" and then uncheck the "Turn on fast startup (recommended)" option if it is enabled. Click "Save changes" to save the changes made, restart your computer, and check if the UNEXPECTED_STORE_EXCEPTION blue screen error is now gone.

Temporary disable antivirus software

As mentioned in our introduction, it is possible that installed antivirus software (third-party) is causing the UNEXPECTED_STORE_EXCEPTION BSOD error. To check if this is the case, temporarily disable the software (and its firewall), restart the computer, and check if the problem persists. If disabling (or uninstalling) the antivirus software resolves the problem, we recommend that you switch to other antivirus software or reinstall the currently-installed product. If you are not sure how to disable your antivirus software, read this guide in which you will find instructions on how to disable some of the most popular antivirus programs.

Re-register Microsoft Store apps using PowerShell

PowerShell is a task automation and configuration management framework from Microsoft consisting of a command-line shell and associated scripting language. In PowerShell, administrative tasks are generally performed by "cmdlets", which are specialized .NET classes implementing a specific operation. You can access PowerShell by right-clicking the Start menu icon in Windows and selecting the "Windows PowerShell (Admin)" result.

Now copy and paste this command (without quotation marks at the beginning and end) into the PowerShell window:

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

To paste it, simply right-click on the Powershell background and the command will appear - press Enter to execute this command. Close PowerShell and restart the computer to check if the UNEXPECTED_STORE_EXCEPTION error is now fixed.

Scan and repair system files

You can also run System File Checker, a Windows utility that allows users to scan for corruptions in Windows system files and restore corrupted files. This guide describes how to run the System File Checker tool (SFC.exe) to scan your system files and repair missing or corrupted system items. The "sfc scannow" option is one of several specific switches available with the sfc command. To run it, you need to open elevated Command Prompt. Type "command prompt" in Search and right-click the "Command Prompt" result. Select the "Run as administrator" option from the contextual menu.

scan and repair system files step 1

To execute the command, type "sfc /scannow" in Command Prompt and press Enter. System File Checker will start and should take some time to complete the scan (about 15 minutes). Wait for the scanning process to complete and restart the computer. Check if the UNEXPECTED_STORE_EXCEPTION blue screen error persists.

Perform a clean boot

When you start Windows using a normal startup operation, several applications and services start automatically, and then run in the background. These programs include basic system processes, antivirus software, system utility applications, and other software that has been previously installed. These applications and services can cause software conflicts, and also cause the UNEXPECTED_STORE_EXCEPTION stop error. A clean boot is performed to start Windows using a minimal set of drivers and startup programs. This helps eliminate software conflicts that occur when you install a program or an update, or when you run a program in Windows. To perform a clean boot, type "system configuration" in Search and click on the "System Configuration" result.

perform a clean boot step 1

In the System Configuration window, click on the "Services" tab and then mark the "Hide all Microsoft services" checkbox. Then, click on "Disable all".

perform a clean boot step 2

Click the "Startup" tab and click "Open Task Manager".

perform a clean boot step 3

Under the Task Manager Startup tab, select all enabled applications one-by-one and click "Disable". Once all programs are disabled, close Task Manager and click "OK" in the System Configuration Startup tab. Restart the computer and check if the UNEXPECTED_STORE_EXCEPTION error occurs.

Check your disk for errors

There is a built-in tool in Windows tool to check the integrity of disks. It examines disks and corrects many types of common errors. You can run this tool from the command line or through a graphical interface. In this guide, we show how to run it through Command Prompt. Open Command Prompt with administrative privileges, type the "chkdsk C: /r" command, and press Enter on the keyboard. Replace "C" with the letter of your hard drive (if it is not the C: drive you wish to scan or the Windows operating system resides on another drive).

check your disk for errors

You will be asked if you want to restart your computer to perform the scan. Type "Y" and press Enter. Wait for the chkdsk process to finish and check if this command resolved the the UNEXPECTED_STORE_EXCEPTION error.

Update drivers

It is possible that the UNEXPECTED_STORE_EXCEPTION error occurs due to corrupt, missing, or outdated drivers. A device driver is software that informs the operating system and other software how to interact with specific hardware. It is rather like a translator between software and hardware, since they often are created by different manufacturers, companies, or individuals. The driver facilitates smooth communication between hardware and software. In most cases, computers are unable to send and receive data correctly without drivers. If the appropriate driver is not installed, the device might not function properly, if at all. You can update drivers by opening Device Manager. Right-click the Start button and select the "Device Manager" result from the contextual menu, or type "device manager" in Search and click the "Device Manager" result.

update drivers step 1

In Device Manager, you will see a list of devices connected to your computer. Look for the device with a yellow exclamation mark beside it. If you see an entry like this, you need to update its drivers. To do so, expand the device section and right-click the hardware installed on the computer. Select "Update driver" from the contextual menu.

update drivers step 2

You will be asked if you want to search for updated driver software automatically or to browse the computer for driver software. If you select the first option, Windows will search your computer and internet for the latest driver software for your device. If you select the second option, you must locate and install the drivers manually. Using this option requires having previously downloaded drivers on your computer or USB flash drive - it is a longer process, because you must download the latest drivers for your device manually by visiting the device manufacturer's official website. Select the option you prefer and follow the instructions. Once updates are installed, restart the computer and check if the UNEXPECTED_STORE_EXCEPTION error persists.

update drivers step 3
