Microsoft has yet to release the Spring Creators Update to Windows 10. We've been sitting here waiting with a story about the launch ready to go, and nothing. Now people are starting to talk.

Rumored to arrive on April 10 alongside Patch Tuesday, the Spring Creators Update, aka version 1803 aka Red Stone 4, is due to deliver new code including a revamped interface, enhanced privacy and security features, and beefed up Cortana search capabilities.
