How to Fix Scripted Diagnostics Native Host Stopped Working

So, here are some troubleshooting methods that will help you resolve the Scripted Diagnostics Native Host Stopped Working issue:

Fix 1: Perform Clean Boot

With Clean Boot, you can troubleshoot a variety of Windows-related problems caused by corrupted program files and system drivers, including scripted diagnostics issues and native host problems. However, while performing a clean boot in Windows 10/11, a user may be at risk of losing data. This is why it is always a good idea to have a backup of all your essential files.

Fix 2: Checking your Disk

This problem could be caused by bad sectors on your disk. We can check your disk fully and see if anything comes up. Make sure you back up all your data and configuration before attempting any of these solutions.

Using the Windows + S keyboard shortcut, enter “command prompt” in the dialogue box, then right-click the app and select “Run as administrator“.
To open a command prompt in elevated mode, type the following command:
```
CHKDSK /R
```
You might be prompted to restart your computer. Follow the instructions and see if the error persists.

Fix 3: Deleting CrashHandler.vbs

For many people, deleting the file “CrashHandler.vbs” was another workaround. This is a file present at every user configuration on the system, which is unique to each user. Nevertheless, if something goes wrong, you can always restore the file if you copy the file to another location.

The file can be found in the following path. Thereafter, rename the file and copy it to another location. You need to delete the files and restart your computer to see if the problem has been solved. In File Explorer, make sure that “Show hidden folders” is enabled since some of these folders are hidden.

Fix 4: Remove The Third-Party Antivirus Program

Windows 11’s Scripted Diagnostics Native Host error was caused by Norton’s associated program, which many users reported as the culprit. Hence, you will need to remove the third-party antivirus program to rule out this possibility. You won’t have to worry since Windows Defender will automatically become active once you’ve removed the third-party program. Follow these steps:

Initially, open the Start menu by pressing the Windows key. Type appwiz.cpl in the search bar and press Enter to launch Programs and Features.
Right-click on the third-party antivirus program in the list. Choose Uninstall.
Thereafter, to continue, click the Yes button in the User Account Control window.
Simply follow the instructions on-screen to uninstall the program.
To apply the changes, restart your computer and check if the error persists.

Fix 5: Diagnosing Problem using the Reliability Monitor

Our next step is to find out where the problem is originating if the above methods are not helpful. We will use a Microsoft application, the Reliability Monitor, to check for the problem. When you diagnose a problem, it streamlines the troubleshooting process and allows you to proceed with the fix. It records all system events along with system updates and all application/system crashes (if any).

Search for “Security and Maintenance” and open the application that appears.
Make sure the “Maintenance” category can be expanded, and the “View reliability history” under “Report problems” can be accessed.
After a few seconds, Windows will display a graph showing all the events that occurred recently. A blue exclamation mark indicates that you have installed an update (security updates, virus definitions, etc.). A red cross indicates that your computer has crashed. All the information related to the crash can be viewed by clicking on it.

Fix 6: Inspect The System Memory

To check if there are any faults in your system memory, use the Memory Diagnostic tool. Here’s how:

Initially, launch the Start menu by pressing the Windows key. Type Windows memory diagnostic into the search bar and press Enter.
To check for any problems, click the ‘Restart now‘ button.
Afterwards, during the restart, the Windows Memory Diagnostic Tool will start scanning for memory errors. Once the test is complete, your PC will boot to the lock screen.
When you log in to your PC, you will see a notification that says, ‘No memory errors were detected’.

Fix 7: Run a SFC And DISM Scan

You can use both SFC and DISM command line tools to repair corrupt files related to the Scripted Diagnostics Native Host application and other operating system components.

To open cmd with administrative privileges, press the Ctrl + Shift + Enter keyboard shortcut after pressing the Windows key.
Afterwards, click the Yes button in the User Account Control window.
To run the SFC scan, type the following command and press Enter:
```
SFC /scannow
```
In order to clear the screen, type cls and press Enter after the scan is complete.

Start the DISM scan by executing the following commands:

DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

Thereafter, you can now close the Command Prompt window.

So, that’s how you can easily troubleshoot the Scripted Diagnostics Native Host Stopped Working issue on your Windows 10/11 PC. It’s our hope that this guide has helped you. If you need any more information, please leave a comment below.
