To prevent leaks, Microsoft has apparently suspended all Windows 10 preview build updates in advance of the Sun Valley event scheduled for June 24. Many fans and press are effectively calling Sun Valley Windows 11, given how substantial this update is. Furthermore, it is easier to call it Windows 11 as opposed to Windows 10 Sun Valley because it is easier to call it Windows 11.

At this time, Microsoft plans to release the latest cumulative update (LCU) as opposed to the preview build, which officials say is necessary to address bugs in the pre-release build, according to this article reported by Windows Latest, This is being done to test the "servicing pipeline" and find bugs in the system to send updates to users as well as the latest builds.

"There is a difference between testing LCU on a release version of Windows 10 and testing it on a pre-release build of Windows 10, finding bugs, and fixing bugs," said Windows Insider Programs Senior Program Manager Brandon LeBlanc wrote on Twitter. This was in response to another Twitter user who claimed that the pause was part of a larger plan to keep Sun Valley a secret.

According to Windows Latest, no new builds will be available until June 24, when Sun Valley will be announced. It is likely that Microsoft intends to move everything to the latest updates during this time.

According to Microsoft, as reported in Windows Latest, Sun Valley will bring "radical" changes that will "reinvigorate" the OS first released in 2015.

"We are now embarking on a multi-year journey to revolutionize the Windows UX platform by delivering the best interactive experience while introducing cutting-edge hardware," a job ad for a program manager, still live at the time of publication It states.

Not much else is known about what we can expect from this upcoming update. It appears to be a radical overhaul of the entire user experience, from the settings page to the Start menu. It will also reportedly integrate elements of Microsoft's now-defunct Windows 10X, which was developed as a lightweight alternative operating system to Chrome OS.

The "Windows 11" event is scheduled for June 24 at 11:00 a.m. EST/PST.
