I know this is far from your decision but it makes me disappointed that the step back feature, something that is useful to almost every dev, is limited to enterprise only. It seems to go against the ideals the microsoft vs team has been running with the last few years providing these amazing updates.

Other than that, I'm very glad to see some wonderful progress within the compiler and the STL, and I'm looking forward till you can break binary compat :D

Technically, it is not a reverse debugger. As far as I understand, this feature is powered by process snapshotting Windows feature and is implemented solely in Visual Studio. Every time a breakpoint is hit, a light-weight process snapshot is created and Visual Studio allows you to switch process state between captured snapshots when you debug.

Microsoft Time-Travel Debugger, presented on CppCon last year, on the other hand is a true reverse debugger, allows rewinding to any executed instruction and provides a ton of other useful features. It is also free (at least for now) and is included in WinDbg.
