As Fast Ring Insiders complete the download of preview build 16288 the Windows team would like to issue as word of caution:
On Build 16288, you will notice that the watermark at the lower right-hand corner of the desktop has disappeared. You will also see that the OS now reports as “Version 1709” which is the official version number for the Windows 10 Fall Creators Update release. However, this is NOT the final build as we’re not done yet. We’re just now beginning the phase of checking in final code to prepare for the final release. So we will have more builds to release to Windows Insiders between now and then. And the desktop watermark may re-appear in these builds.
For those attempting to read the Windows 10 tea leaves, it would seem the engineering team would rather be blunt and clear. Be there no confusion about it, there will be at least another build hitting devices before Windows 10 Fall Creators Update is said and done.
On a side note, there does appear to be an issue with the download of preview 16288 that users should be aware of.
Hello Insiders! For those of you who aren't able to download the 16288 PC Fast build, we're investigating the root cause. More info soon!
