Infrastructure

I do not understand how to send feedback to the desired section, so that if you're sorry, something is wrong (to be honest, you've all confused it here).
1) It is written that it is supported by Windows XP (at least in the Russian version of the site). Specify that Windows XP is not supported in the 6th version right on the download page, why a separate page for describing the OS versions?
2) In the Russian version of the site there is no feedback, I spent half an hour looking for where to write a review and half the hour was spent on registration (why is there no ordinary e-mail? If I register on any site I want to write a review, I will simply lose time).
3) Something I do not like msi-installers, because in the world there are free exe-installers like "nsis".
4) Is there a way to trick the installer by changing the registry and running on the old version of the OS? (well, it's just for pampering, check how it will work))).
