Re: ENS Registry keys not being removed after uninstall

Jump to solution

Hi @User66539864 ,

Thank you for reaching us on community !

I would like to inform you that the registry "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender DisableAntiSpyware" and "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender DisableAntiVirus" are not created by installing ENS or VSE . 

Most probably these keys must be present on a windows 8 or later operating systems by default as these are used to enable or disable anti malware and anti spyware provided by windows defender.

But i would like to inform that these registries can be accessed/created/modified by the operating system itself once it detect an anti malware program in the machine like ENS. This is because windows has designed to turn off defender if there are any other Anti-malware  installed on the machine.

below are the KB articles that might help you in understanding this :

Hope that helps,
