Win 10 Pro 64 no longer updates - apparently a number of weeks now?

Try the repair install first and if that doesn't work roll back before the AU. Hopefully, the first will work and the second won't be necessary.

Success !!!

To all who helped on this...my problem has been completely corrected...but I can't say 'solved'...since I don't know exactly what happened. What I did is go back to a complete Acronis tib system backup of my Windows Pro C: drive system from July 1, 2016

After start up...I just left everything alone and low and behold...everything...including Anniversary Update, downloaded and installed without a hitch. Last 24 hours of testing/using also went without a hitch...Updates - Firewall issues gone - and all my accessories and options respond and are working fine...even Cortana is zipping along.

Obviously immediately saved another current Acronis image and backed that up twice to two different drives ?

Wish I could report what worked...but glad I'm up and running with (so far) a new Win 10 Pro 64bit system and Anniversary update that is functioning great !!

Many thanks to all that helped....

Great news! Smart move to do an immediate new backup! And 2 at that! Keep it running like a champ. Now you're all set for next Tuesday when the monthly patches come out. Another backup after that.

Good job!
