ISOs allow a clean installation of Windows 10 in build 18990, a version released by Microsoft to Insiders following the Fast Ring channel in late September.
There are three different versions of these ISOs that you can download from the Microsoft Insiders page:
The normal build, the enterprise version, but also the version in Home China for the friends of the operating system from China. On the ISO download page, in addition to the images of build 18990 (Fast Ring), there are also images from the Release Preview channel, ie the upcoming Windows 10 18363 build.
These ISO images can be used for a clean installation of the operating system, which is very convenient for users who are part of the Windows Insider program and need to restore their devices.
At the same time, they can be used to test a specific build in a closed environment, such as a virtual machine, before the official release of its "fixed" Windows 10 20H1.
"Except for registered desktop apps, when you enable this setting, most open UWP applications will now restart automatically! "To reduce login time, UWP applications are restarted to a minimum, in a suspended state, giving Windows and other applications more resources to start," Microsoft said when it released this build of Windows 10.
The development of the operating system Windows 10 20H1 is expected to be completed in the spring of 2020 and according to the standard Microsoft program, this should be done in March. Its release for everyone could start in April or May 2020.
