Windows 10 May 2019 Update

Windows 10 May 2019 Update (also known as version 1903 or "19H1") is an upcoming Windows 10 update which is scheduled to be released in May 2019. It is the first version of Windows 10 to use a more descriptive codename (including the year and the order released) instead of the "Redstone" or "Threshold" codename.

This update was supposed to be released in April 2019 but was delayed by Microsoft to May 2019 to improve the update quality.
