If you have been holding off installing the Windows 10 April 2018 Update, perhaps because of the numerous problems that have hit the latest version of Windows 10, that doesn’t mean Microsoft has forgotten about you. In fact, it's just released a pair of cumulative updates for people running Windows 10 Creators Update and Anniversary Update.

If you’re running Windows 10 Creators Update (Version 1703), then you should see an update titled KB4103722. This update, according to Microsoft, includes a number of quality improvements to make the operating system work better, but it doesn't add any new features – for that you’ll have to upgrade to the Spring 2018 Update.
