In Windows 8.1, if you wanted to change your settings, you had to go on a treasure hunt. Some settings were in the Windows Settings app, which was accessible via the Charms bar, while others were in Control Panel. It was difficult to remember where each setting was located.
In Windows 10, you'll find almost all settings in the Settings app, accessible from the bottom of the Start menu. It's cleanly and logically organized, with nine sections: System, Devices, Network & Internet, Personalization, Accounts, Time & Language, Ease of Access, Privacy and Update & Security. Click on the icon for any section, drill down, and you'll easily navigate to what you need. There's also a search bar so that you can forgo browsing and search for a specific setting instead.
People who do a great deal of customization and tinkering (including me) won't find everything they need in Settings. If you want to assign your PC a static IP address, have your system display files that are normally hidden, display file extensions for common files or access a host of other techie settings, you'll have to go to the old standby, Control Panel. On the other hand, having settings that you don't use much relegated to the Control Panel makes sense, because it makes the main Settings app easier to navigate.
Hello, Action Center
New in Windows 10 is the Action Center, which is accessible via an icon on the right side of the Taskbar. The Action Center performs two functions: It displays notifications for such things as new emails and security and maintenance messages, and it gives you access to a handful of common settings for such tasks as connecting to Wi-Fi networks, turning Bluetooth on and off, and changing brightness settings. The notifications for new email, security alerts and others first appear on their own on the lower right of the desktop and disappear after a few seconds. But they live on in the Action Center, so that you can attend to them there when you want.
For example, if you tap an email notification, the email opens in the Mail app. Tap a security notification, and you'll be taken to the appropriate tool. When I received a notification that I could speed up my PC because three unnecessary programs were launching on startup, I was sent to the Task Manager, which let me stop those programs from running.
At the bottom of the Action Center are icons for making quick changes to common Windows settings. You can turn Bluetooth on and off, change your screen's brightness, and switch between tablet mode and non-tablet mode, among other settings.
