A new update for Windows 10, the April 2018 Update (was referred to as the Spring Creators Update, also known as Windows 10 version 1803, code name Redstone 4), is being worked on by Microsoft for a while, and should be released on early 2018. According to online sources, build 17133 should have been the final build to be released to the wide public, but it appears now that the release was delayed (sources: one, two).
I have been asked by many users to provide an updated version of 7+ Taskbar Tweaker, and since 17133 was believed to be the final version, I began working on it. For now, I did enough adjustments for the tweaker to load without crashing, but didn’t test all of the tweaks. I plan to do that in the near future. As with previous updates, those who contributed to the project can download the early alpha version here (removed) and try it out.
Update (May 20): A non-beta 7+ Taskbar Tweaker version with Windows 10 April 2018 Update support is now available. You can get it here.
