Extended battery life
Performance improvements are about more than speed. For example, your laptop battery lasts longer with power-saving features, such as adaptive display brightness, which dims the display if you haven’t used your PC for a while.
Take control of problems
Many of you asked us to stop Windows from sending so many alerts and messages and to give you more control over messages. In Windows 7, you get to choose the messages you want to see.
Even if you don’t change a thing, you’ll still see fewer notifications and icons popping up because the Action Center consolidates alerts from 10 Windows features, including Security Center and Windows Defender.
Rather than popping up with a message in the lower right of your screen, if Windows 7 needs your attention, you’ll see an Action Center icon and can find out more by clicking it. If you don’t have time to look at the alert immediately, Action Center will keep the information waiting for you to address later.
Faster, more responsive performance
Nobody likes to wait. So we’ve focused on the basics that can impact the speed of your PC. Windows 7 starts up, shuts down, resumes from standby, and responds faster. You’ll have fewer interruptions and can recover more quickly from problems when they do occur because Windows 7 will help you fix them when you want.
