Unlike FAQ Schema rich results, How-To Schema rich results didn’t launch across both mobile and desktop. This appears to have now changed based on what I’m seeing using a VPN across different countries, browsers and screen sizes.
When the testing of How-To Schema rich results on desktop was happening across 3 separate instances, there was several different formats at play. This is similar to the mobile treatment, where Google may pick 1 of 5 different variations.
In the case of the 3 separate desktop How-To Schema rich result variations (which may return in the future), one of those was picked as the launch variation. Here’s what all desktop How-To variations look like:
The difference between the test variations and the launch version relates to prominence. The 2 other variations (which haven’t been seen since being tested) either have an image thumbnail or an additional link for steps.

At the time of writing this post, Google hasn’t updated their guidelines relating to the desktop How-To Schema treatment. But based on my experience with Google tests and full rollouts, this feels like a pretty clear rollout to me.
Try doing a search for any of the examples mentioned in this post and you should see the How-To Schema treatment on desktop. I’d expect to see some new variations of the treatment over time, so keep an eye out and let me know if you see something new.
