Hi and welcome to the forum
This is a complex issue as there were some changes in the Anniversary Update releases. There are 3 different versions and it doesn't appear you have the latest. Try using the
<windows+logo-key+R> command and type in
"WINVER", and it will return the exact version and build number. The latest is
v1607 b14393.10. Anything less than that you may need to update your computer further.
There are several posts that may help you here: 1.) This is the overall Anniversary Update post from our Admin-Owner on getting the Anniversary Update
b14393.5. Later on in this post the newer update for
b14393.10 is also posted. Here's that link:
Windows 10 - Download Windows 10 Build 14393.10 Anniversary Update 2.) This next link is also referenced in the Anniversary Update, and explains that some options such as the GPO options were removed from W10 Pro as you suspected, but we think this may be an incomplete assessment of all the changes. Here's that link:
Microsoft removes policies from Windows 10 Pro - gHacks Tech News 3.) Finally take a look at this link which gives you the direct download links to the
b14395.10 ISO file Anniversary Update here:
Microsoft Update Catalog Regarding your other comments, no, Pro Upgrade has not been downgraded to Home as far as we know about. The comment you make about controlling the updates is controlled in a new W10 feature which came out early this year in 2016, called
WUDO. And you are incorrect in asserting that it does not work in W10 Pro. I have Pro installed on 3 of my 5 W10 machines,
and I can make the changes to get updates, or disable the updates completely, or adjust them to getting them from other machines on my home network or get them from other machines on my home network AND from random computers on the Internet. It sounds like you may need to do another W10 Pro clean install from the sources I listed above, which are the only reliable ones I've seen. You could also have hardware problems that could cause this sort of problem on your machine that would keep this option from working correctly, such as failed RAM sticks or Hard Drive. Have you fully tested your RAM sticks on the computer running the W10 Pro and the Hard Drive (e.g:
MEMTEST & SEATOOLS)?? Have you tried installing on a different machine? Different machines with different hardware such as a desktop PC and a laptop can produce different results.
I would make sure that you have the correct latest version of the Anniversary Update installed,
v1607 b14393.10, reinstall if necessary, and you should get all the
WUDO options I mentioned. If not, you need to test your hardware and repeat. Several of us are getting this option across multiple machines including machines built back 10 years old (XP-era machines). You should also consider replacing your hard drive, repeating the clean install of W10 Pro on that drive even if it passes Diag testing. If the problem persists you should consider testing on a different computer altogether (preferably a modern computer made in 2009 or after).
A worthwhile note here is that the Anniversary Update has been confirmed to be flawed by several of us who have done extensive testing on v1607, but Microsoft has not yet acknowledged this or given us an ETA on a fix. If you read through all the linked threads you can view the discussion in gory detail. The problem you mention however, is a problem specific to your computer, either failed install or failed hardware or both.
Best of luck,
