First and foremost, you must already be a Windows Insider to take advantage of this trick. If you are a Windows Insider, first launch the registry editor. Insiders should then navigate to “HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostUISelection”. You will then need to double-click on “UIContentType” and change it to “Skip”. You should then find “UIRing” and change it to “WIF”.
Then navigate to “HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsSelfHostApplicability”. You will then need to change the value of both “Ring” and “Content Type” to "Skip".
Once you have completed these steps, restart your computer and check for updates. The Skip Ahead build should be there for users to download and install. Please note, that although you will be able to access Windows 10 19H2, you will not technically be part of the Skip Ahead ring.
Microsoft's Windows Insider is a software testing program that allows users who own a valid license of Windows 10 or Windows Server 2016 to test out the pre-release builds. Millions of testers have participated in the program since its release in 2014. Those who are subscribed to the Fast ring are able to test features as soon as they are available, while those subscribed to the Slow or Release Review rings can test features once they have been slightly updated.
At the moment, testers have access to the upcoming Windows 10 19H1 update. The latest update is slated to release in April 2019, while Windows 10 19H2 will likely be released in October 2019. Although users were able to join the Skip Ahead ring last week, the enrollment period was quite short.
We currently know very little about Windows 10 19H2, but we already know quite a bit about Windows 10 19H1. For example, Windows Insiders are able to run traditional desktop (Win32) apps in mixed reality. Testers are also able to play State of Decay for free to test Window’s gaming updates. We can only hope that both the April 2019 and October 2019 updates will have fewer bugs than Microsoft's disastrous Windows 10 October 2018 Update.
