The Windows update on May 10, 2019 is the most significant due to the large number of features it brings to the desktop.
The leader is a new software called Windows Sandbox that allows users to run an isolated desktop environment to test "unreliable" applications.
The update of May 2019 also separates Cortan from the search, alters how Windows 10 manages storage and can remove buggy updates.
Although the new upgrade from Microsoft is incredibly tempting, some fans who wanted to buy it failed.
Along with previous US technology updates, no explanation was given if it was unavailable to download after users started the "Windows Update" section on your device in Settings.
But, as noted by Windows Latest, Microsoft now issues messages on the Windows Update page, alerting users why they can not get the latest software.
A screen shot is displayed in the socket from one of their test devices displaying the prompt.
It reads: "Windows Update on May 10, 2019 is on its way.
"We offer this update to compatible devices, but your device is not ready for it.
"When the device is ready, you'll see the update available on this page. You do not have to do anything at this point."
Asked about the new ZDNeta queries, Microsoft confirmed that they were introduced to "improve the quality / transparency of the Windows update process".
As a rule Microsoft is gradually developing its new software and it seems to be doing the same with the update from May 2019.
But as stated in the above message, users who can not get a new operating system will have to wait patiently until they are available to them.
The company based in Redmond also said it plans to automatically start up with the update of Windows 10 hardware and will automatically update the update in April 2018.
It has been noted that "machine learning" will be upgraded to send updates to devices with older operating systems.
Microsoft said, "We are now beginning to build and practice the Machine-based Design Process (ML) to update the devices that update the April 2018 and earlier versions of Windows 10 to ensure we can continue servicing these devices and provide the latest updates , security updates and enhancements. "
It is not clear when Windows 10 users will start receiving automatic updates.
