I am having a very similar problem to this topic: http://www.bleepingcomputer.com/forums/t/591853/windows-10-browsing-and-apps-not-all-working-like-it-should/?p=3828789
In summary after updates have installed and everything looks good random drivers start installing - Intel Grapics / Network / wifi / device manager has all these new hardware installs when I look back in device manager, a rouge Skype.exe and one drive.exe install by themselves and hyper v modules appear to be added.
However it is occurring on all my hardware and Mac. IPv6 installs by itself and also creates a IPv6 tunnel on my router which I have tried to disable however it keeps reactivating. My ADSL service also looks compromised but my isp insists that I'm not even though I'm on router number 4 - this has been occurring for 3 months- I'm rebuilding every couple of days and it's driving me crazy!!! Plese help!
