Devices Basics

Your PC is compatible with a wide variety of external hardware devices, including keyboards, mice and touchpads, removable and network-based storage, printers, multiple displays, and more. Many of these devices will work with little or no intervention on your part. But some require additional configuration.

For the most part, hardware devices are configured in Bluetooth & devices settings. To find this interface, open the Settings app and navigate to Bluetooth & devices.

Entries for the Mouse and Touchpad pages will only appear when those peripherals are available. Pen & Windows Ink, curiously, appears regardless of whether your PC even supports those capabilities.
Bluetooth & devices settings lets you add and configure the many types of devices that work with Windows 11. But you can also click the "View more devices" link just above "Bluetooth" to access other areas of the Settings app related to hardware, including those for Sound and Display settings.

Connect a device and install drivers if needed
When you connect a new hardware device to your PC, Windows will try to install a basic class driver so that you can begin using it right away. You will typically see a notification banner alerting you when this happens.

Windows 11 will then look to Windows Update for better or updated drivers and other software. So you should consider visiting Windows Update after connecting a new device to see whether updated drivers are available.
As you probably know, Windows Update can be found by opening Settings and navigating to Windows Update.
There will be instances in which neither Windows 11 nor Windows Update can supply a driver. The easiest way to see this isn't all that easy, as you have to find and launch the legacy utility Device Manager. You can do so via Search---just type device to find it in the search results---or right-click the Start button in the Taskbar and choose "Device Manager" from the Quick access menu that appears.
You can also open Quick access by typing WINKEY + X.
When a hardware device isn't correctly configured with a working driver, you will see a yellow exclamation point (or "bang") next to it in Device Manager.

That's your cue to find the hardware maker's website and download the driver directly.

Indeed, even if Windows 11 or Windows Update offered a device-specific drive, you can oftentimes find a newer or better driver from the device maker's website. This is especially true for video and printer drivers, which are often accompanied by custom software applications that let you take full advantage of the underlying hardware.

Here, as you might expect, Google is your friend.
