Application failed to initialize error using Windows Defender

Hi,

I've read the issue that you have with the windows defender and here are the steps to resolve the issue:

Here are some of the reasons why Windows Defender may stop working, or encounter problems when trying to restart. If there is a virus infecting the computer and damaging the registry, windows defender won’t start. The other one is if you have uninstalled a virus protection on the computer and it’s not totally uninstalled on the registry of the computer this can also block windows defender from opening. If Windows Defender has been manually disabled on the computer then it won’t start. If the one of the files on the windows operating system has been corrupted, so we just need to type sfc/scannow on the command prompt so that it will be automatically be repaired. And lastly, if the operating system that you had installed is not genuine.

We can start the windows defender by doing the following:

1. Click Start button.
2. On the start search bar, we need to type “services.msc.
3. The Services window will open up.
4. On the right-hand side, you will see a list of programs on the services windows.
5. Scroll to the very bottom part of the list and look for Windows Defender.
6. Right-click Windows Defender.
7. Click on “Proprieties”.
8. The “Properties” window will load up.
9. On the “General” tab.
10. Set the Startup type to “Automatic (Delayed)”.
11. On the Service Status, it will show: “Stopped”.
12. Click on “Start” at the upper left side of the screen.
13. The Windows Defender will start.

If this won’t resolve the issue, we need to check if you have any other virus protections installed on the computer that might be blocking the windows defender from starting up. You can also check for updates that will activate the windows defender.

If there are no other virus protection installed on the computer, have a system restore on the computer.

1. Click Start.
2. Click All Programs.
3. Put the mouse pointer over the word Accessories.
4. Click System Tools.
5. Click System Restore.
6. On the Welcome to System Restore page.

8. Click Next.
9. On the Select a Restore Point page.
10. Click the most recent system restore point in the on this list.
11. Click a restore point list.
12. Click Next (A System Restore message may appear that lists configuration changes that System Restore will make. Click OK.)
13. On the Confirm Restore Point Selection page, click next.
14. System Restore brings back the previous Windows XP configuration, and then restarts the computer.
15. Log on to the computer as an Administrator then click OK on the System Restore Restoration Complete page.
