After releasing a ton of cumulative updates for almost all the versions of Windows 10, including its upcoming 20H2, Microsoft has now released something for the Dev Channel Insiders, as well. Windows 10 Insider Preview Build 20190 is now out for Insiders, bringing an improved Graphics Settings experience and a new post-feature-update experience.

We know that it doesn’t always feel clear what changed with a major update, or even how you can learn about and try out new features and improvements. This means that updates can feel time consuming without real benefit to you, and we want to change that. We’re introducing a new first run experience via the Tips app that highlights the most exciting changes on your PC after a major Windows 10 feature update is installed. After installing this build, Insiders will see the Tips app is launched highlight some of the most recent new features from the latest Insider Preview builds in the Dev Channel. To see this experience on your device, make sure the “Show me the Windows welcome experience” checkbox in Settings > System > Notifications & actions is checked.
