Windows 10 Anniversary Update version 1607 upgrade

KAV (Kaspersky) is incompatible with Windows 10 Version 1607
Important Notice About KAV & Windows 10 Anniversary Update Patch
http://community.kaseya.com/xsp/f/142/t/22290.aspx

“This week Microsoft released Windows 10 Anniversary Patch. Our testing shows there is incompatibility with Kaspersky Antivirus, the underlying engine in Kaseya Antivirus (KAV). More specifically, KAV will not install on Windows 10 Anniversary Edition and will be uninstalled if an endpoint is upgraded to Windows 10 Anniversary Edition.

Kaseya has reached out to Kaspersky and can confirm they are working on an update to their software. Kaseya will test and issue as patches for VSA R9.2 and VSA 9.3. We expect to release these patches before the end of August based on Kaspersky’s delivery date to us.”

Blocking Windows 10 Version 1607 – Deny KB3012973
Microsoft will gradually push out Version 1607 and it will arrive for WSUS on August 16. Right now Kaseya shows 2 new KBs for 1607 – KB3176929 and KB3176495. These are cumulative updates to Windows 10 Version 1607 – not the upgrader.
Deny KB3012973 – It looks the 1607 installer is the same KB used to upgrade Windows 7 and 8.1 over the past year. A new flavor of KB3012973 showed up on August 2 as “Feature update to Windows 10, version 1607”. This appears to be the 1607 upgrade. It remains denied in all of our patch polices as a KB Override. With that said Microsoft has a history of making the Windows 10 upgrades a “moving target” and we will continue to monitor for other KBs and update this blog accordingly.
We have approved KB3176929 and KB3176495 as they are updates to an existing 1607 install.
