You could fix the problem by following the ways to Fix ‘Windows Defender Crashing’ issue on Windows 11/10.

Disable Antivirus System

1. Almost everyone has an antivirus system on the Windows PC.
2. We don’t recommend the users disable the security system since it leaves the computer vulnerable.
3. It’s a risky bet, but I will leave this judgment in your responsible hands.
4. Windows has optimized the software incorporated with the third-party security solutions.

Run Full System Scan

We are assuming that the antivirus system is already on the Windows PC. Obviously, you shouldn’t run a full system scan in normal mode. Instead, you should switch to safe mode. In safe mode, Windows turns off third-party drivers, services, and programs. Let me show you how to get to safe mode in Windows 10 and Windows 11 versions.

1. Press the “Windows” key to open the PC’s “Settings” menu.
2. Under System, look for “Recovery” and open it.
3. Look for “Advanced startup” and click on the “Restart now” option.
4. Choose “Restart now” from the menu.
5. Wait for the operating system to start up in recovery mode. This takes less than a minute.
6. Select “Troubleshoot” from the menu.
7. Pick “Advanced options” from the list of choices.
8. Pick “Startup Settings” from the list of options.
9. Press the Enter key or click the “Restart” button.
10. Press the 4 key to open “Enable Safe Mode” without networking or the command prompt.
11. Have the computer do a full system scan.

Fix Corrupted Windows System Files

System files are often broken in Microsoft’s operating system, which is one of the main reasons why Windows Defender doesn’t work. MS made sure that the software came with tools that can be used to check the integrity of the system files.

1. Type “command prompt” into the search bar and run as administrator.
2. Type the command (sfc /scannow) and hit the “Enter” key.
3. The Windows machine is where the check begins.
4. There is no broken file system on the system.

Reinstall Windows Software

1. Save the data you’ve stored on a different device, like a USB flash drive or hard drive.
2. Use a different computer to make a bootable USB flash drive, since the malware stops Microsoft’s Windows 11 Installation Media tool from working. My computer was being attacked by malware, and that made it impossible for Rufus to work.
3. Format the whole drive and don’t reinstall the operating system on just one partition. During the setup, delete the drive and start over with the partitions.
4. Write down the Windows product key, and we have a tutorial on how to do that. I took a picture of it and put it in the gallery on my iPhone. You should put the photo in the “cloud” so you won’t lose it.
5. Find the CD with the driver on it or copy the link to the manufacturer’s site. I have saved the page with drivers for both my laptop and my desktop motherboard, so I never have to worry about drivers.

Uninstall Windows Feature Update

Windows Defender app not opening: Microsoft has made mistakes in the past, like when they added features that slowed down the computer. Luckily, the software doesn’t have any restrictions, and users can remove feature updates from their PCs. Set up a restore point so that if things go wrong, you can go back to an earlier time.

1. Press the “Windows” key to open the PC’s “Settings” menu.
2. Under System, look for “Recovery” and open it.
3. Look for “Advanced startup” and click on the “Restart now” option.
4. Choose “Restart now” from the menu.
5. Select “Troubleshoot” from the menu.
6. Pick “Advanced options” from the list of choices.
7. Choose “Uninstall updates” from the menu.
8. You have two choices, but you should click “Uninstall latest feature update.”
9. Click “Uninstall feature update“.

If your Windows Defender keeps crashing on a PC running Windows 11 or 10, don’t ignore it. People who don’t follow tech news may not know that Microsoft has repackaged all the old security solutions and given them the name “Windows Security.” Thousands of computers come with third-party security software already downloaded and installed, but Windows Defender is always the first line of defense.
