The next possible solution is repairing and resetting the Windows Defender app. You can easily do this via the Settings application. Follow these steps:<\/p>\n
\n- Firstly, launch the Settings application. To do that, open the Start menu and select the gear icon. It would be easier to tap the
Windows + I<\/code> combination, though.<\/li>\n- After the Settings<\/em> application flies out, click on Apps<\/em> on the left side.<\/li>\n
- Next, go to the main window and click on the Apps & Features<\/em> section.<\/li>\n<\/ul>\n
<\/p>\n
\r\n \r\n ![\"Go]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- On getting to the Apps & Features<\/em> interface, use the search box to find the Windows Security<\/em> app or scroll down.<\/li>\n
- Click on the three dots to the right of Windows Security<\/em> and select Advanced Options<\/em>.<\/li>\n<\/ul>\n
<\/p>\n
\r\n \r\n ![\"Click]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- Scroll down to the Reset section when you see the Apps > Apps & Features > Windows Security interface<\/em>.<\/li>\n
- Click on Repair<\/em>. Doing this will prompt windows to search for problematic Windows Security<\/em> files and replace them.<\/li>\n<\/ul>\n
<\/p>\n
\r\n \r\n ![\"Search]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- If repairing the program doesn\u2019t work, click on the Reset button. Then, click on Reset<\/em> again in the confirmation dialog.<\/li>\n<\/ul>\n\r\n\tNote<\/div>\r\n\tNote that the app\u2019s data, such as your saved preferences (exclusions and scheduled scans) and sign-in details, will be wiped out.<\/div>\r\n<\/div>\r\n\n
\n- Restart your computer after the process is complete and check for the blank screen on Windows Security again.<\/li>\n<\/ul>\n
Fix 3: Reinstall the security app via Windows Terminal (Admin)<\/h3>\n
If the problem persists after repairing and resetting the app, your next course of action should be reinstalling it via Windows Terminal (Admin).<\/p>\n
The command will remove every instance of Windows Security and reinstall it.<\/p>\n
This particular fix mainly helped correct a problem that came with a Windows Insider Preview build. The issue has been resolved in subsequent updates.<\/p>\n
So, if you\u2019re still running the preview build, you don\u2019t have to apply this fix. Instead, head to Windows Update and install the latest official version of Windows 11.<\/p>\n
However, if you want to fix the problem for now, here are the steps you should follow:<\/p>\n
Follow these steps:<\/p>\n
\n- Right-click on your Start button or go to your keyboard and press the
Windows + X<\/code> key combination.<\/li>\n- Select Windows Terminal (Admin) in the Power User menu that flies out on top of the Start button.<\/li>\n<\/ul>\n
<\/p>\n
\r\n \r\n ![\"Select]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- Now, select Yes<\/em> in the User Account Control pop-up.<\/li>\n
- After Windows Terminal (Admin) appears, type the following and press the Enter<\/em> key:<\/li>\n<\/ul>\n
Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage<\/pre>\n <\/p>\n

\nFix 4: Redeploy every native Windows app<\/h3>\n
The next method is reinstalling all your native Windows applications. Some of these programs\u2019 files may have been corrupted during your upgrade to Windows 11.<\/p>\n
So, head to the admin version of Windows Terminal again. This time, type the following codes and hit the Enter<\/em> button on your keyboard after typing each line:<\/p>\nSet-ExecutionPolicy Unrestricted\r\n\r\nGet-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register \"$($_.InstallLocation)\\AppXManifest.xml\"}<\/pre>\n <\/p>\n

\nFix 5: Repair broken Windows files<\/h3>\n
Some Windows system files may have also been affected during the upgrade. Repairing these files should resolve the problem in this case.<\/p>\n
Running the System File Checker (SFC) is a great option here. It\u2019s a command-line program that deals with system file integrity violations.<\/p>\n
It scans protected Windows files and automatically replaces those that are missing or damaged.<\/p>\n
Microsoft recommends that you run the Deployment Image Servicing and Management (DISM) tool before running SFC.<\/p>\n
Both programs work hand in hand. DISM uses the Windows Update client to download the replacement files to be used by SFC.<\/p>\n
You\u2019ll have to launch Command Prompt as an administrator to get the privilege required to run these tools correctly.<\/p>\n
Here are the steps you\u2019ll be following to apply this fix:<\/p>\n
\n- Launch the Run window. Press
Windows + R<\/code> or right-click the Start button and choose Run from the Power User menu.<\/li>\n- After the Run window opens, type CMD<\/em>.<\/li>\n
- Next, press
Shift + Ctrl + Enter<\/code> on your keyboard to open the Command Prompt as an administrator.<\/li>\n- Select Yes<\/em> in the User Account Control<\/em> confirmation window.<\/li>\n
- Once the Command Prompt window appears, type the following code and press the Enter<\/em> button on your keyboard:<\/li>\n<\/ul>\n
DISM.exe \/Online \/Cleanup-image \/Restorehealth<\/pre>\n <\/p>\n
\r\n \r\n ![\"Enter]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nAs we mentioned, DISM uses the Windows Update client to download repair files. The System File Checker then uses these files to fix integrity violations.<\/p>\n
In some cases, the DISM tool may fail to initiate the client and fetch the files. This could be because you\u2019re not connected to the Internet, or the Windows Update service has encountered a problem.<\/p>\n
There\u2019s a workaround. You can use a Windows installation DVD or the Windows 11 ISO you used for the upgrade as your repair source. Since you\u2019re on Windows 11, it would be best to go for the latter.<\/p>\n
Now, mount the ISO file (double-click it or right-click and select Mount) as a virtual DVD. Then, enter the following code:<\/p>\n
DISM.exe \/Online \/Cleanup-Image \/RestoreHealth \/Source:X:\\FileSource\\Windows \/LimitAccess<\/pre>\nWhen entering the code, make sure you replace the Source:X:\\FileSource\\Windows part of the command with the path to the ISO file\u2019s Sources folder.<\/p>\n
The ISO file should appear on This PC after mounting it.<\/p>\n
<\/p>\n
\r\n \r\n ![\"Type]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nSince it\u2019s mounted as drive F on my computer, the code should look like this in my case:<\/p>\n
DISM.exe \/Online \/Cleanup-Image \/RestoreHealth \/Source: F:\\sources \/LimitAccess<\/pre>\n <\/p>\n
\r\n \r\n ![\"type]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nYou can also enter only F: as the source.<\/p>\n
After the tool completes the process, type the following code on the next line and hit Enter:<\/p>\n
sfc \/scannow<\/pre>\nIt may tell you that a repair is pending, and you have to reboot your PC. This is likely due to the DISM process you just ran. Restart your computer as instructed.<\/p>\n
<\/p>\n
\r\n \r\n ![\"Type]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nAfter your PC reboots, rerun the command. It should tell you that the process will take some time.<\/p>\n
The tool will show you the following message if it does not find corrupt files:<\/p>\n
\u201cWindows Resource Protection did not find any integrity violations.\u201d<\/p>\n
<\/p>\n
\r\n \r\n ![\"Windows]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\nIf it finds and replaces corrupt files, you\u2019ll see the following message instead:<\/p>\n
\u201cWindows Resource Protection found corrupt files and successfully repaired them.\u201d<\/p>\n
Fix 6: Reset Windows 11<\/h3>\n
If none of the above methods worked, then you have to reset the operating system. Using the reset function, you\u2019re essentially reinstalling the operating system as a whole.<\/p>\n
This way, files and system components that were botched during the first installation can be reinstalled. This method worked for most people.<\/p>\n
Before you start, however, you should understand a few things:<\/p>\n
\n- You have to back up your files if you haven\u2019t already. Even if you choose to keep your files, it would be best to stay on the safe side.<\/li>\n
- If you\u2019ve installed apps after your upgrade or you chose the option to keep your third-party programs when you installed Windows 11, they\u2019ll be uninstalled during the process. Only apps that came with your PC will be retained.<\/li>\n
- If you haven\u2019t already, update the operating system before performing the reset. You can also allow Windows to install updates before resetting your PC.<\/li>\n
- Remember to follow the steps to a tee.<\/li>\n<\/ul>\n
Now, down to business:<\/p>\n
\n- Firstly, launch the Settings application. Open the Start menu and select the gear icon. It would be easier to tap the
Windows + I<\/code> combination, though.<\/li>\n- After the Settings<\/em> application flies out, go to the left side of the window and click on Windows Update<\/em>.<\/li>\n
- Click on Advanced Options<\/em> under the Windows Update<\/em> interface.<\/li>\n<\/ul>\n
<\/p>\n
\r\n \r\n ![\"Click]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- Scroll down and select Recovery<\/em> on the Advanced Options<\/em> page.<\/li>\n<\/ul>\n
<\/p>\n
\r\n \r\n ![\"Select]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- Select Reset<\/em> next to Reset PC<\/em>.<\/li>\n<\/ul>\n
<\/p>\n
\r\n \r\n ![\"Select]()
\r\n <\/div>\r\n <\/div>\r\n<\/div>\n\n- Select the Keep My Files<\/em> option.<\/li>\n
