One of the nicest features that Microsoft added to Windows 10 is the revamped Action Center and the new notifications system. Instead of just seeing a bunch of glowing icons on your taskbar, Windows 10 notifications pop out of the bottom-right side of the screen. For some people, however, these notifications might be coming and going too quickly.
By default, Microsoft sets Windows 10 notifications to pop out and stay visible for five seconds before disappearing into the Action Center. That’s a good amount of time for most people, but if you'd prefer that notifications stick around just a little bit longer, you can make that so.
