Microsoft has released Windows 10 Version 1903 to the MSDN
Although Microsoft emphasizes that Windows 10 version 1903 will continue to be tested, it will not be officially released until the end of next month. But now the official version has been completed, so Microsoft has begun to distribute in advance, such as the MSDN subscription portal can download the new version.
It should be emphasized that this MSDN subscription portal is a corporate subscription website provided by Microsoft. It is not the MSDN that we often download images. The Subscription Portal is currently available in Windows 10 Version 1903 consumer versions, Home and Professional, as well as related versions of Enterprise Channel. These versions provide ISO image file downloads for enterprise-level users to download and then manually upgrade the deployment, as well as SDKs based on this version.
As for when Microsoft will launch image files for ordinary users in advance, it is still unknown, but I believe that the MSDN version will soon be leaked.
