How to Reinstall Windows Security In Windows 11

How to Reinstall Windows Security In Windows 11
Windows 10 and Windows 11 have a built-in (and pretty good) Microsoft Defender Antivirus (Windows Defender) managed through the Windows Security panel. In some cases, Windows Defender or the Windows Security control panel stop opening, an empty white window is shown instead of a dialog interface, the application does not start when called through the Settings panel or the shortcut command ms-settings:windowsdefender . In this article, we will look at how to fix common errors when the Windows Defender Security Service window cannot be opened.

Code: Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

After windows 11 update, in this pc not showing folders (download, document, pictures, music etc...) only showing drives (windos c, windos D, windos E) but folders are showing quick access in left side.
How i get those folders to this pc?

GUYS for whoever not any of the way is working. The easiest way out is resetting the pc. And no data will be lost. Just empty out the personal data from the one in which windows is installed to the others(only which is absolutely necessary). Then go for reset pc > remove everything > only disc C(the one with windows) > fully clear the drive > cloud install . That is it. No data is lost and fresh windows is installed.
I had all the problems in the world. the security file was missing. The virus messed up the registry. the wscsv file was missing and everything else went wrong too. Defender had a black screen. The goddamn reset pc button was not working. I then did an advanced startup.
