I have a Windows 7/64 desktop and laptop each fitted with the Intel AC7260 Adapter and relative software and driver (i.e. version 16.7.0. and earlier versions also tried) and experience occasional conflicts reported by Windows Reliability History of APP CRASH's either one or both as Stopped Working of the following:
1] Intel Proset / Wireless Zero Configuration Service.
2] Windows Wireless LAN 802.11 Extensibility Framework.
I have set a temporary cure by setting Intel Proset / Wireless Zero Configuration Service to Disabled in Services. Time will tell if this provides a cure but it would be interesting to find out if anyone else has had the same problem or has a better solution.
