Microsoft has promised to stop installing unstable updates when you click «Check for Updates» and they will now be delivered. Instead of automatically installing such updates, Windows provides you with a Download and Install Now button. The button started showing up on PC today.
We previously warned that clicking the «Check for Updates» button often results in unstable updates being installed. Windows Update usually waits for large updates to be installed, such as the buggy Windows 10 October 2018 update and monthly cumulative updates C and D. However, if you clicked «Check for Updates» at the wrong time, Windows will simply install those updates immediately. You would not see any warning that this was happening, and there was no way to cancel it.
In other words, the «Check for Updates» button often meant «Please give me unstable updates that need more testing.» Microsoft was actually warning people not to click on it in blog posts that no average Windows user would read.
Microsoft announced significant changes to Windows Update on April 4, 2019. Instead of automatically installing these updates, Windows will present them as optional in the Settings app in Windows 10. The Windows Update panel will include a Download and Install Now link if these options are not needed. -stable updates are available. You have the choice of whether to install them, even if you clicked Check for Updates.
