Although everyone was expecting the release of Windows 10 Spring Creators Update (aka Redstone 4 or version 1803) on April 10, the company decided to delay the release of the new updated OS. 
We currently do not know much more, as Microsoft itself has never confirmed 10 in April as Spring Creator release date, but many who know what's going on inside the company say there will be a delay in the release of the new OS.
Microsoft, for its part, released the first cumulative update for Spring Creators on April 10 (for Insiders), fixing a bunch of bugs and addressing security flaws that were present in other versions of Windows 10.
This cumulative update may take us one step closer to the forthcoming Spring Creators public release, although it is not clear at the moment when it will happen.
It will probably take a few days before the release to the public but it would be very interesting to know why Microsoft delayed the release of the new update.
If it is a last minute error, it should make us all wonder what the company is serving us, although everything seems to work smoothly for Insiders.
Πηγές within the company that talked to Windows Central, reported that Microsoft found a "blocking bug" (blocking bug) last weekend, which will have to be fixed before the operating system officially starts to be made available.
The new operating system version will be available to the public at waves, which means that systems are updated gradually.
Microsoft itself is expected to provide more information on developing the Windows 10 Spring Creators update very soon, as the first update wave will be available by the end of the month.
