DISM will scan the Windows component store for corruption and attempt to repair any issues using online resources from Microsoft. This process might take some time, depending on the extent of corruption and your internet connection speed. Allow it to complete fully.
Run SFC: After DISM completes, in the same Command Prompt window, type the following command and press Enter:
```
sfc /scannow
```
SFC will scan all protected system files and replace corrupted files with cached copies. This process also takes time to complete. Do not close the Command Prompt window until the scan is 100% complete.
Review SFC Results: Once SFC finishes, it will display a message indicating the outcome.
- “Windows Resource Protection found corrupt files and successfully repaired them.” This is the ideal outcome. It means SFC found and fixed corrupted system files. Restart your computer and check if the issue is resolved.
- “Windows Resource Protection found corrupt files but was unable to fix some of them.” This indicates that SFC found corruption it couldn’t automatically repair. In this case, you can try to manually analyze the SFC log file to identify the problematic files and attempt manual replacement, or you can try running SFC again after a reboot.
- “Windows Resource Protection did not find any integrity violations.” This means SFC didn’t find any corrupted system files. While this is a good result in terms of file integrity, it suggests the UNEXPECTED STORE EXCEPTION error might stem from other causes.
Restart Your Computer: Regardless of the SFC result, it’s generally recommended to restart your computer after running both DISM and SFC to ensure any repairs are fully implemented.

Running SFC and DISM is a crucial step in diagnosing and resolving system file corruption that could be triggering the UNEXPECTED STORE EXCEPTION BSOD.

3. Turn Off Fast Startup¶

Fast Startup is a Windows feature designed to speed up the boot process. While generally beneficial, it can sometimes interfere with hardware initialization and driver loading, potentially leading to the UNEXPECTED STORE EXCEPTION error, especially on systems with older hardware or specific driver incompatibilities. Disabling Fast Startup can help determine if it’s contributing to the issue.

Disabling Fast Startup:

Open Power Options: Search for “Power Options” in the taskbar search box and select “Power Options” from the results. Alternatively, right-click on the Start button, select “Power Options,” and then click on “Additional power settings” in the right panel.
Choose What the Power Buttons Do: In the Power Options window, click on “Choose what the power buttons do” in the left-hand menu.
Change Settings That Are Currently Unavailable: If User Account Control is enabled, you’ll need to click on “Change settings that are currently unavailable.” This will allow you to modify certain power settings that are normally locked.
Uncheck “Turn on fast startup (recommended)”: Under the “Shutdown settings” section, uncheck the box next to “Turn on fast startup (recommended).” If the option is greyed out, ensure you have clicked “Change settings that are currently unavailable” in the previous step.
Save Changes and Restart: Click “Save changes” at the bottom of the window and then restart your computer.

After disabling Fast Startup, use your computer as usual and monitor if the UNEXPECTED STORE EXCEPTION error persists.
