Ksharon and Massimo: you both make some good points. We have rolled out a handfull of Windows 10 systems and they are Pro. We have also installed added protection for advanced threats and the like. Overall, a lot more of extra management (have not added them to Zenworks yet) to keep those bad patches at bay, but so far do-able. The OS is not so bad on our older systems, just not sure how long that will continue to be the case and whether or not they will continue to get updates (you know, the hardware compatibility collusion factor, all the mfgs making you buy new all the time). It is going to be HUGELY expensive for us, a small company, to have to buy new hardware AND get software assurance just for the OS, especially if we have to go Enterprise. It's a big decision to make.
