Microsoft has started rolling out the Windows 10 May 2020 update for a couple of Surface devices. (via MSPU)
These Surface devices include Surface Pro X, Surface Laptop 2 and Surface Pro 5.
To check for updates, simply head over to Settings > Update & security > Windows Update, on your PC.
The Windows 10 May 2020 is the most recent Windows 10 update that was released in May this year.
However, the company was not able to deliver the said update to all the Surface devices (or non-Surface users) as per the rollout schedule because of many technical difficulties ranging from hardware to software.
Microsoft is still investigating a lot of issues and yet many many Windows 10 users are waiting for the update to arrive, including myself.
If the Windows 10 v2004 is not showing up on your device just yet, you can follow this tutorial (safe) to update your PC to the latest version.
