Specific features of Windows Defender
* A redesigned and simplified user interface – Incorporating feedback from our customers, the Windows Defender
UI has been redesigned to make common tasks easier to accomplish with a warning system that adapts alert levels according to the severity of a threat so that it is less intrusive overall, but still ensures the user does not miss the most urgent alerts.
* Improved detection and removal – Based on a new engine, Windows Defender
is able to detect and remove more threats posed by spyware and other potentially unwanted software. Real Time Protection has also been enhanced to better monitor key points in the operating system for changes.

can be run by all users on a computer with or without administrative privileges. This ensures that all users on a computer are protected by Windows Defender
