Windows Defender and Windows SmartScreen can help guard your PC against viruses, spyware, and other malicious software in real time. Family Safety gives your kids some independence while still keeping tabs on them.
Mouse and keyboard
You can use a mouse and keyboard to work on your Windows desktop the way you always have. And things you do with touch, like using apps from the Windows Store and getting around on your Start screen, can also be done with a mouse and keyboard.
