Right so I got the name completely wrong in my last post, I will admit that straight away; talk about a curve ball.
I have been having a play around with the technical preview of Windows 10 and I am liking it a lot. I believe it is definitely an easier migration path for enterprise users still on XP. Is the reason why Microsoft went from 8 to 10 because of the theory that enterprises have a tendency to miss out on a release when doing their client migrations. So going from XP to Windows 7 and missing Vista and going from Windows 7 to Windows 9 or in this case Windows 10. Who knows.
Charms are still there in Windows 10
There was a rumor going around in the software development community a while back that Charms will be disappearing in the next Windows release. As this image shows, they are still there.
However if you have a Store app open on your desktop and use the same key combination of Windows+C, then you also get access to a lot of the same functionality within the app.
Why is this such a big deal
If you are developing Windows store apps, you need to be sure that what you are coding will be supported in future Windows releases. If you are adding functionality that allows your users to change app settings, they would now be accessible from both the Charms and context menu in the app. Maybe the Charms will disappear by the time Windows 10 gets its full release some time in 2015. At least this way all that work doing app settings fly outs will not go to waste. The other option would be to add the same functionality to a bottom menu in the app, similar to what you do in a Windows Phone app.
