Few low-level security updates have been observed. Microsoft has not changed all of it but Windows 8 manage memory in a sensible way that makes security hard to exploit.

You can also install any other antivirus. Windows defender will disable itself when you will have your own antivirus program.

Windows will scan the file and send its signature to Microsoft’s server. If installer of application found ‘good’ then it will allow application to run. If it contains malware, Windows will prevent you to install this software. If windows would not be able to recognize or found new then it will ask you to bypass the warning.
This feature will help inexperienced users who download malicious software from internet. Even new malware can detect by SmartScreen filter as an unknown new program that Windows will allow with caution.
New computer with UEFI firmware are able to provide Secure Boot guarantee over old BIOS. Only especially sign and boot program can run. In current scenario, malware could install a malicious boot loader, which actually loads before Windows boot loader. It start boot level toolkit before Window launch. Toolkit hides itself from Windows and antivirus software.
