In Windows 7, Windows Defender is the name of a limited antispyware solution. Beginning with Windows 8 and continuing in Windows 10, Windows Defender is a full-featured security solution (and the successor to Microsoft Security Essentials) capable of detecting all sorts of malicious software. Because it supports the ELAM feature, it also prevents rootkits that try to infect third-party boot drivers. In Windows 10, Windows Defender also includes network behavior monitoring.
Windows Defender is designed to be unobtrusive, updating automatically and providing messages only when required to do so. It is intended primarily for use in unmanaged PCs. In enterprise settings, you’ll probably want to use an alternative antimalware solution. Microsoft’s System Center 2012 Endpoint Protection, which uses the same engine as Windows Defender and also includes support for ELAM, is designed for use with enterprise-management tools. A number of third-party solutions that meet those same criteria are also available.

- Open Settings.

While Windows Defender doesn’t specify how long you can disable real-time protection, “temporary” usually means until the next time you reboot your computer.
