When my company pushed Windows 10 it did it two ways. Replaced the older computer or pushed Windows 10 if it was anewer PC. In all cases I had to reinstall Emonitor and FactoryTalk again. I copied the disk to the C drive made it Windows 7 compatible and ran it as admin. Never had any issues. I had to disable the driver protection to install the CMC driver for the new meter. I also had to make two register changes to get Windows Mobile Device Center to work properly. Have about 30 PC running it across the fleet.
