2. Exploit guard
EMET (Enhanced Mitigation Experience Toolkit) was a Microsoft tool which would prevent malicious code from exploiting security flaws in Windows systems. Microsoft retired it, but has implemented several of its features into the Fall Creators Update. Most of the tools of Exploit Guard are turned on by default. To see what they are and to adjust them individually, launch the Windows Defender Security Center app. (It’s listed on the app list in the Start menu.) Click "App & browser control."

Click "App & browser control" to access Exploit Guard
Scroll the panel down to "Exploit protection" and click "Exploit protection settings".

Find "Exploit protection settings" under "Exploit protection"
Under “System settings,” you can turn off or on six exploit protection tools: control-flow guard, data execution prevention, force randomization for images (mandatory ASLR), randomize memory allocations (bottom-up ASLR), validate exception chains (SEHOP), validate heap integrity.

Under "Program settings," you can add an executable/program to tweak its functionalities to prevent it from being exploited by malware or intrusions. The 21 settings include the six under "System settings" and others such as block remote images, disable Win32k system calls, and validate API invocation.
