Question

Answer 1

Hi Burhan, Referring to the info on your screenshot, it looks like you might have policy key set blocking you from access in the settings of Defender. If you are admin on the device, try running this in an elevated PowerShell prompt: REG delete "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender\Policy Manager" /v "AllowUserUIAccess" /f and Set-MpPreference -UILockdown $false Try accessing the settings again. Hope this helps,
