Stop windows defender so I can install bitdefender

How can I stop windows Defender so I can install Bitdefender

Hi:

>>I have never used BD, but....

AFAIK, most (all?) of the major 3rd-party AVs will automatically disable WD when you install them.
Unless BD specifically advises to manually disable WD first, you ought not to need to do that.

But here is a tutorial:

Windows Defender - Turn On or Off in Windows 10 - Windows 10 blog

You can always go into the Control Panel afterwards to check that it is off after you install BD.

Thanks,
MM

Yeah I've installed Mcafee Internet Security 2016, Kapersky Internet Security 2016, Trend Micro Antivirus + Security, and Bitdefender Antivirus plus all on Windows 10 workstations. During each, Defender was disabled and did not interfere.

Man, you sure used lots of paid antivirus.

I didn't pay for any of those licenses. These were all work computers.

You should also disable WD's services to ensure no interference. Run CMD as admin and copy/paste:

reg add "HKLMSoftwarePoliciesMicrosoftWindows Defender" /v "DisableAntiSpyware" /t REG_DWORD /d "1" /f
reg add "HKLMSystemCurrentControlSetServicesSense" /v "Start" /t REG_DWORD /d "4" /f
reg add "HKLMSystemCurrentControlSetServicesWdFilter" /v "Start" /t REG_DWORD /d "4" /f
reg add "HKLMSystemCurrentControlSetServicesWdNisSvc" /v "Start" /t REG_DWORD /d "4" /f
reg add "HKLMSystemCurrentControlSetServicesWinDefend" /v "Start" /t REG_DWORD /d "4" /f

Thanks to you all I finally got Bit defender Installed and windows defender is off. Thanks again Jerry
