Why am I always tempted by updates? On the well loved principle of 'if it ain't broke, etc' these things are probably best avoided.
Anyway I've now downloaded the new Windows 10, and all seems to be going well. I don't like the new weather forecast graphics as much as the old ones, the new Email is probably simpler to use, and Picasa 3 (which does my photo processing) is a tad more complicated (to which, no doubt, I shall become accustomed in time).
Windows 10 opens up with 'inspirational' photos of jellyfish, mountains, seascapes, etc, which is quite pleasant. So I'm quite happy with it; but then I was perfectly happy with Windows 8.
Have you made the leap? If so, how do you find it?
p.s. I was amused by the above on-screen message. I managed to take breakfast, a walk with Bok, and a spot of log sawing, all whilst 'it wasn't taking long'.
