Microsoft has delivered a new batch of driver and firmware updates for Surface Pro 7 and Surface Book 3. Both are getting some major camera improvements, along with some other improvements. Following are the improvements coming with today's updates for Surface Pro 7 devices running Windows 10 May 2019 Update, version 1903, or greater.

Microsoft usually releases Surface updates in stages, which means not every device receives the update at the same time. After installing new firmware updates, head over to the Start button> Power > Restart to finish the installation process. Do note that firmware updates cannot be uninstalled or reverted back to an earlier version. More details on today's updates for Surface Book 3 are available in this support document; for Surface Pro 7, head over to this link.
