How to disable windows defender for long time?

Hi Andrew,

If I understand you correctly you are willing to disable Windows Defender from your system. I would like to know few more things to understand the issue in a better way.

• Why are you trying to disable Windows Defender? Are you planning to install any third party security software?
• From where you have followed the steps to disable Windows defender using registry?
• Are you logged in as Administrator?

The steps which you have mentioned to disable Windows Defender using gpedit.msc is correct. If you are unable to disable it then you may do that by stopping the service responsible for Windows Defender. Here are steps which you may follow to perform the
same task.

• Press Windows key + R to open run box.
• Type services.msc and hit enter.
• There should be 2 services: Windows Defender Service
  and Windows Defender Network14.
• Right click on each and press stop.

If you will stop the service responsible for Windows Defender then it will not run till it is stopped. Do get back to us with all the information required and result of proposed suggestion. We will be happy to assist you further.
