Will monthly update install for machines?

Hi, if I understand the question, you have Win 10 machines which have not yet been offered the AU upgrade.

If you wish, you can apply this manually:
Windows 10 ISO Download - Windows 10 Forums
- then mount the iso or burn it to DVD or create a bootable USB drive with Rufus (free)
or
Use the Microsoft media creation tool to force the Windows 10 Anniversary Update today | Windows Central
- which can create a bootable USB device if you wish


Having a bootable medium available has several advantages:
- you have some basic recovery options when using it to boot
- you can use it for an in-place upgrade repair install if required, assuming it matches the installed OS
- you can update multiple machines without downloading 3Gb or so per machine

And before you upgrade, if you haven't already, create a full disk image or set of images.
e.g. Macrium Reflect (free).
Things can sometimes go wrong.
