how to activate??? the key does'nt working...plz help. thanks
You won't notice any difference between .502 and .540. Just cumulative update is all. Wait till next update and see what happens. Next week I think.What is difference between 502 (old) and 540 (this) minor versions of windows. I have 502, and I can't update to the newer one. Differences between 1607 and 1703 are noticable, but what about minor versions?
