Unable to turn on Windows Defender
Scenario 1] One of the most common behaviors of Windows Defender is that if it detects a third-party antivirus software, then Windows Defender will shut itself off. Windows is designed to detect the presence of security software installed, and we often get to see the notification in the Action Center. One of the common issues we have seen in the past is when there are multiple security software installed. It often creates a conflict between them and in the end, it creates more trouble than doing any good. Frequent freezing, crashing to applications are some of the common issues which occur when you install more than one antivirus software.
So to avoid this situation, Windows Defender will turn itself off when it detects another security program. Likewise, if this security application has a Firewall, then Windows Firewall will also stop working. So in case you want Windows Defender to work, then you will have to uninstall your third-party security software and reboot the system.
Often users may be unaware if security software is indeed installed or not because when you buy a new laptop, mostly it comes with a trial version of security software like Norton, McAfee, etc. Then when you install applications like Flash or Java, it might prompt you to uninstall free security scanner when most of them don’t notice. So it’s best to search your PC if you’re not sure if security software is installed or not. Once it’ removed you may need to turn it manually back on.

Make sure you have set your Window clock & date set properly and then try to turn your Windows Defender back on and see if it works fine. It’s strange, but most of the Windows operating system functions work, based on the system date and time. So an incorrect date or time could trigger abnormal behavior in your Windows OS.
Scenario 3] Another important thing that could cause issues is, if you Windows is not up to date, in terms of Windows Update. This could cause issues in Windows Defender or any other Windows core application. When it comes to any security software, it always needs the latest signature updates and other Windows core updates to keep your PC secure. So I would highly recommend to run a complete Windows Update, then go into Windows Defender and run an update from there as well. Then see if your Windows Defender is working fine.
4] Other Common Issues: The above-discussed scenarios are the most common ones. Revit families download. Apart from these, there could be some minor issues that could affect the working of Windows Defender.
