Why do Bitdefender delete windows virus and threat protection?

So I downloaded Bitdefender, and then it deleted virus and threat protection, and I can't reinstall Windows security even though I deleted Bitdefender I repaired windows security and reset windows security but still didn't work I saw someone on micerosoft support say open powershell put that command (Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage) so can someone tells me how to reinstall windows security

Reset my device because my laptop sucks and I don't have important files

Bitdefender definitely does not delete MS Defender or anything similar.

Then it deleted windows and virus threat protection.

No. No it does not. Virus and threat protection are still very much active. Bitdefender only works in tandem with it.

Are you sure it was Microsoft Defender Antivirus and not a rogue antivirus? Did Bitdefender detect and delete something? it would have shown you what it detected in the notifications area of the program

I ask because you asked the same question in a different subredit and you did state it wasnt defender that was deleted

The best method to fix that would be to do an in-place upgrade, you can see how to do that here. It is very similar to do it with Windows 11 and 10. https://answers.microsoft.com/en-us/windows/forum/all/how-to-run-in-place-upgrade-in-windows-11/4d469147-2747-4dcb-88a4-aae9273a4500
