Hi all,

According to http://www.microsoft.com/windowsembedded/en-us/product-lifecycles.aspx
MS does support WEC 7 until April 13, 2021, which is more than 6 six years.
But dropping wec 7 support would mean dropping complete ce support as the successor wec2013 is not supported by qt and qt 5.x needs quite some patches to build ( and building things like quick controls need some hacky patches, as it depends on accessibility.)

Wec2013  is using a prerelease forked version of 17.00 Compiler (as used in vs 2012)  compile OS and applications.
The support runs till October 10, 2023.
MS is actually fixing bugs in this compiler (which is delivered with wec 2013)  and has done so on our request ( i remember some optimisation internal compiler error when building qtwebkit from qt 4.8.5)
We are using qt 4.8.x on ce 6 and wec 2013 and we use qt 5.4 on wec2013. We skipped wec 7 so being able to use newer c++ compiler features  but in hindsight it was a pain, so i understand that many people stick with wec 7.
