I would consider Win10 if there is an option to disable the phone home stuff. Without the LTSB license, you simply cannot deactivate all stuff. Why are various IP addresses and domains white listed in signed kernel mode dlls?<p>Microsoft still thinks the will get away with this. Their bad. They will get problems with their mass collection of data from sensitive areas like doctors, lawyers, etc.<p>Windows 7 is a very good OS until at least 2020 (minus recent phone-home updates). And every other OS including OSX, iOS, Android and Linux are more forthcoming and less hostile to the end user. (all tracking, crash reporting and phone home features can be deactivated in all OS except Win10)
