How to Fix Event 1000 Application Error on Windows?

Users might notice an error message of ‘Event ID 1000’ in their Event Viewer log. This entry basically means that a specific application crashed due to unknown events. Along with the error code, you will also be given the file path of the application which crashed.

The reasons for this issue can be multiple; the application itself might be having issues when running and crashes intermittently. In another case, a module of Windows itself might be crashing due to corrupt system files or incompatible settings, etc.

In this article, we will go through all the reasons as to why this error occurs on your computer and what you can do to solve it.

What causes the Event ID 1000 Application Error?

After receiving initial user reports, we came to the conclusion that this error occurred due to several different reasons. Some of the reasons as to why you see the Event ID in your Event Viewer are but not limited to:

Before we move on to the solutions, make sure that you have an active internet connection and are logged in as an administrator on your computer.

Solution 1: Running a System File Check

Before we try anything else, we should first make sure that the copy of Windows on your computer is indeed complete and there are no discrepancies in it whatsoever. There are numerous instances where the computer doesn’t work as expected or gets into unexpected errors like the one under discussion if it has outdated or missing files in its system. In this solution, we will run the System File Checker and see if it diagnoses any file and fixes it.

1. Press Windows + S, type “command prompt” in the dialogue box, right-click on the application and select Run as administrator.
2. Once in an elevated command prompt, execute the following commands one by one and make sure that they complete:

   

sfc /scannow

DISM /Online /Cleanup-Image /RestoreHealth

3. The latter command fixes any issues which the system file checker diagnoses when running the scan. The file checker basically analyzes all the Windows files against a pre-defined manifest. If it sees any discrepancies, it alerts you and tries to replace the bad file with a fresh copy which it downloads from the web.

If your system scan turns out just fine, and you are still seeing the error message, you can continue with the other solutions listed below.

Solution 2: Uninstalling the Specific Application

Another thing which you should try is either uninstalling or replacing the specific application which was causing you trouble. Normally, you will be able to instantly diagnose which application was giving the Event ID 1000 by retracing the file path. If you have successfully identified the application, you can follow the steps listed below to uninstall it. If you cannot determine which application is causing the error, you can move on to the Clean boot solution which we have listed down below.

1. Press Windows + R, type “appwiz.cpl” in the dialogue box and press Enter.
2. Once in the application manager, browse through all the different applications installed and after locating the problematic application, right-click on it and select Uninstall.

   

3. Restart your computer completely and then check if the issue is resolved.

Solution 3: Clean Booting your Computer

If both the above methods don’t work out and you are unable to determine the application which is causing the problem, you can try clean booting your computer. When you clean boot your computer, your computer only turns on with the necessary drivers and all external applications are disabled by default. In clean boot, you can check whether you still get the error message. If you don’t, you can try enabling each application one by one or by chunk and then check again. This will help identify which application was causing the problem.

1. Press Windows + R to launch the Run application. Type “msconfig” in the dialogue box and press Enter.
2. Navigate to the Services tab present at the top of the screen. Check the line which says “Hide all Microsoft services”. Once you click this, all Microsoft related services will be disabled leaving behind all the third-party services (here we are assuming the Windows files are working just fine so we are not disabling them).
3. Now click the “Disable all” button present at the near bottom at the left side of the window. All the third-party services will now be disabled.

   

4. Click Apply to save changes and exit.
5. Now navigate to the Startup tab and click the option of “Open Task Manager”. You will be redirected to the task manager where all the applications/services which run when your computer starts will be listed.

6. Select each service one by one and click “Disable” at the bottom right side of the window.

7. Now restart your computer and check if the problem appears again. If the issue doesn’t occur, enable a chunk of services and then try again. See if the error is resolved.

Solution 4: Updating Windows to the Latest Build

If all the above methods don’t work and you still receive the same error message, the last thing you can do is make sure that your Windows is installed to the latest build. There are frequent errors in Windows where the operating system gets into a bugged state with some of its modules or some services don’t work properly. In this solution, we will navigate to the Settings and make sure Windows is updated to the latest build.

1. Press Windows + S, type ‘Update’ in the dialogue box and open the application.
2. Now Settings will be opened up. Click the button Check for updates. Now your computer will automatically check for any latest updates available and install them on your computer.

   

3. Restart your computer after the installation of updates and check if the issue is resolved.
