Two comments...first on your other post that talked about 1803 vs 1809 Win10...1803 is no longer being withheld for MOST people. The file deletion issue only affected people who relocated their Documents / Music / Video etc. libraries from their default locations. This has been fixed.
If you still don't have 1809, it is likely you have iCloud installed. MS is withholding the update for people that have iCloud installed until MS and Apple can figure out why 1809 breaks iCloud.
Now, the other comments....you said that iCloud is only necessary if you are collaborating and sharing files between a Windows computer and a MAC. Again, this is not true.
iCloud is handy for people with an iPhone or iPad who takes video / pictures. Having iCloud on your PC allows you to use File Explorer on your Windows PC to browse any pictures or Video you may have taken with your iPhone / iPad. (Assuming you have your Apple device set to sync to iCloud).
This is the easiest way to get a video off your iPhone to your Windows computer.
I do this all the time as I am also a video editor that uses Vegas Pro 16.
Keep in mind, even if you have iCloud on your PC, you can FORCE 1809 by downloading it directly from MS site. It will warn you that you have incompatible software first.
