    Yep, indeed. I had a different view on the "customer" thing because for 
    us, the customers mostly deliver the software. :)

    I get your point now.


Windows 7 is EOL. Period. If it costs you, as a developer, additional money to support an EOL'ed, unsupported version of an operating system then you will need to pass that onto the customer. By still supporting Windows 7 we, as developers, are just enabling those customers to keep from updating. There are very few real reasons *not* to update to at least Windows 8. At some point the customer needs to understand that they are not going to get any new features. They current piece of software will keep working (Assuming a perpetual license) but nothing new will be supported. I've had requests to back port our software to CentOS 6 and once you explain the cost to them for us to maintain all the extra development hardware, extra engineering to develop codes that are not supported on the old compilers, it becomes cost prohibitive to maintain those versions.

+1 to remove Windows 7 support.
