    for windows 11 users:

    try this command :

    Add-AppxPackage -Register -DisableDevelopmentMode "C:\program files\windowsapps\Microsoft.SecHealthUI_1000.22621.1.0_x64__8wekyb3d8bbwe\appxmanifest.xml"

    get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

    The term 'Reset-AppxPackage' is not recognized as the name of a cmdlet, function, script file, or

    operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try

    again.
