Although everyone was waiting for the release of Windows 10 Spring Creators Update (also known as Redstone 4 or version 1803) on April 10, the company decided to delay the release of the new updated operating system. 
At the moment we don't know more, as Microsoft itself never confirmed April 10 as date release of Spring Creators, but many who know what is going on inside the company report that there will be a delay in the release of the new OS.
Microsoft, for its part, released the first cumulative Spring Creators update on April 10 (for Insiders), correcting a bunch of bugs and fixing security flaws in other versions of Windows 10.
This cumulative information perhaps bringing us one step closer to the upcoming public release of Spring Creators, although it's currently unclear when that 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 who spoke with Windows Central reported that Microsoft found a "blocking bug" last weekend that needs to be fixed before the operating system can be officially released.
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 to deploy the Windows 10 Spring Creators Update very soon, as the first wave of updates should be available by the end of the month.
