In a blog post, Microsoft announced the full availability of the Windows 10 April 2018 update for general Windows 10 users.
The update is available if you check manually for Windows Updates from settings and Microsoft will start pushing it out on the 8th May. Microsoft uses a process of gradual testing using Machine Learning for each range of PCs and laptops to identify compatible devices before pushing out en masse, and Microsoft hopes to push this update out even faster than the Fall Creators Update, which rapidly became the most widely used version of Windows 10.
Microsoft also hopes a faster update process (63% faster than the Fall Creators Update) will ease the adoption process further.
Users can download the update by Checking for Updates in Settings now. Read more about the what to expect from the Windows 10 April 2018 update here. You can learn about how to install Windows 10 April 2018 update here. You can learn how to download Windows 10 April 2018 Update ISO here.
