The next big Windows 10 update, originally expected earlier this month until Microsoft delayed it at the last minute because of a bug causing blue screens of death, at last has an official name and a release date.

As expected, Microsoft is dropping its "themed" names for this update, instead calling it simply the Windows 10 April 2018 Update, with the version number 1803. It'll be available to download manually from April 30, just scraping into April. Broader distribution through Windows Update will start on the next Patch Tuesday: May 8.
