Integrated Power shell
Unlike XP and Vista PowerShell 2.0 is built-in. After all systems administration is all about scripting and automation.
AppLocker
Software Restriction Policy is replaced by this. We can create rules to specify which files are allowed to run and unspecified files are not allowed to run by default. There is a log only option called “Audit mode” which allows unspecified apps to run but logs an event (there is an AppLocker event log).
Other features i liked would be Windows XP mode and native support for VHD's.
