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.

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.
