Microsoft promised to stop installing unstable updates when you click "Search for updates" and now deliver. Instead of automatically installing such updates, Windows gives you a "Download and install now" button. The button started appearing on computers today.
We have previously warned that clicking the "Search for updates" button would often install unstable updates. Windows Update is normally waiting to install major updates like Windows 10's buggy October 2018 Update and monthly cumulative updates of C and D. If you clicked "Check for updates" at the wrong time, Windows would only install those updates immediately. You wouldn't see any warning this happened and there was no way to interrupt it.
In other words, the "Check for Updates" button often means "Please give me unstable updates that need more testing." In fact, Microsoft warned people who didn't click on it in blog posts that no average Windows user would read.
Microsoft announced major Windows Update changes on April 4, 2019. Instead of installing the updates automatically, Windows would present them as optional in the Settings app on Windows 10. The Windows Update panel will have a link "Download and install now "when these less stable updates are available. You can choose to install them, even if you clicked "Search for updates".

As Bleeping Computer discovered, some Windows 10 users already see this interface. An "Additional Updates Available" section offers a cumulative update that is not yet automatically installed. We haven't seen this interface on any of our Windows 10 systems yet, but the Windows Central Zac Bowden has. Microsoft is likely to roll it out slowly.

The change shows up on systems running Windows 10 May 2019 update, also known as version 1903 or 19H1, but can also be displayed on older systems.
When the update of May 2019 is available, it will not be installed immediately – you must click on one of these "Download and Install Now" links. If you do not, you can stick to your current version of Windows 10 for up to 18 months after it was released. And when the C and D updates arrive at the end of a month, you can safely click "Search for updates" without installing them. Just wait a few weeks and you will receive the updates in next month's B update after they have been tested.
