Can windows 10 updates rollback?

Yes ,You can also uninstall the regular, more minor updates that Microsoft constantly rolls out, just as you could on previous versions of Windows 10.

To do this, open the Settings app, navigate to Update & security > Windows Update, select “Advanced options”, select “View your update history”, and then select “Uninstall updates”.

If a build you install is too unstable, you can roll back to the one you were previously using. To do this, open the Start screen or Start menu and select Settings. Navigate to Update & security > Recovery. ...Windows 10 will automatically remove these installation files after 30 days.

if a build of windows 10 is unstable, you can roll back

Builds are treated practically like new versions ofWindows, which is why you uninstall a build in the same way you'd uninstall Windows 10 and revert toWindows 8.1 or 7. You'd have to reinstall Windows 10or restore your computer from a full-system backup to go back to a previous build after those 30 days are up.
