One is a tour of what your update installed. The other is a checklist of accounts and subscriptions Windows wants you to complete. They look alike, arrive together, and answer to completely different switches.
Ask ten users to describe the annoying blue screen after an update and you will get two different screens described as one. There is the welcome experience, a what's-new tour, and the finish setup screen, the Lets finish setting up your device checklist. They appear in the same week, in the same style, and each has its own Settings toggle and registry value. This page separates them cleanly, so the next time you fix one and the other appears, you will know it is not the fix failing. It is the other nag.
The welcome experience is the tour. After a feature update and your first sign-in, Windows shows a series of friendly pages about what is new and what you might like to try. It is informational, appears once per update, and is gone when you click through it. Its switch is the Settings toggle Show the Windows welcome experience after updates and when I sign in, backed by the registry value SubscribedContent-310093Enabled under ContentDeliveryManager. The video's script disables this screen too, which is why its topic list names the welcome experience separately from the setup popup.
The finish setup screen is the checklist: Lets finish setting up your device, with Continue and Remind me in 3 days. Unlike the tour, it is not about the update at all; it reuses the post-update moment to present pending account and service items. Its switch is the toggle Suggest ways to get the most out of Windows and finish setting up this device, backed by ScoobeSystemSettingEnabled under UserProfileEngagement. Different screen, different value, different switch.
The classic support story: a user disables the welcome experience, feels done, and meets the checklist at the next update, concluding the fix failed. It did not fail; it was aimed at the other screen. The two screens even look like cousins, full-screen, blue, friendly, which completes the confusion. The remedy is simply to know the pair exists and switch off both if your goal is a clean sign-in. The one click script in the video exists precisely because doing both, every time, by hand, is the part people skip.
There is a third suggestion surface worth separating so it stops muddying reports: the lock screen. Windows Spotlight pictures and the tips and fun facts shown over them are controlled in Settings, Personalisation, Lock screen, not in the Notifications page at all. If a user complains about suggestions and points at the lock screen, neither of the two switches in this guide is the tool. Naming the three surfaces correctly, tour, checklist and lock screen, ends most of the confusion around this whole topic.
Watch the video to see both screens switched off together by the one click script, which is the whole point of using it.
Watch Full VideoBecause they are separate features with separate controls. The welcome experience toggle stops the after-update tour. The finish setup checklist needs its own toggle, Suggest ways to get the most out of Windows and finish setting up this device, or the ScoobeSystemSettingEnabled registry value set to 0.
Yes. The video page lists both jobs for the script: disable the setup popup and disable the welcome experience. That pairing is deliberate, because most people who hate one of these screens hate the other as well.
No. Lock screen suggestions and Spotlight facts are a third surface, controlled under Settings, Personalisation, Lock screen. Turning off the two sign-in screens does not change the lock screen, and vice versa.
