I jumped off the deep end and upgraded my main laptop to Windows 10. Besides bring my work machine, it is also my sim machine since I am at the road over 6 months out of the year as a network / IT security consultant and trainer. Haven't had any problems and FSX-SE, with tons of Orbx (mesh, global, vector, openLC and fat regions) use mainly A2A aircraft with Rex textures and Active Sky for weather... So far so good. Anyway it works well for me...
