Right now I wonder if a browser or chrome embedded framework (and then when applications that use it update past the cut-off version) is the 'killer app' that motivates upgrades. The CEF cut-off for win7/8/8.1 was when their extended support periods ended, and presumably they upgraded the underlying SDK they to rely on features not present pre-win10, and presumably oct 2028 (+3 years) is when the same will happen again

Just made dirty hack and be able to run latest LibreOffice 25.8 on Win7 despite official "unsupported status". Save dialog is not working but luckily software is cross platform and has it's native dialog and it can be enabled in options.
