Microsoft explains that Surface updates are released in stages, so you may not see this update for the Surface Pro 8 right away. The release only started rolling out on May 24, 2022, so there's a good chance that you'll have to wait to see it.

You can get the latest update for the Surface Pro 8 through the Windows 11 Settings app by searching for optional updates. You can also grab it through Microsoft's website to manually install it.

After installing it, make sure to restart your machine to complete the process.

The Surface Slim Pen 2 supports haptic feedback when writing or drawing. It also has a flattened design that looks more like a carpenter's pencil than the cylindrical Surface styli of yesteryear.
