The only way to use windows 8 ans 10 is to upgrade evepilot to use .Net 4.5 and switch a way how bot create screenshots.
.Net 4.5 is not included to windows 7 by default, so bot will have to install .Net framework with windows 7. Some people may cancel .Net framework installation at this stage (they might not like additional download) and I will loose customers.

On the side note windows 7 is better then windows 8 or 10 in many aspects. Most of people use windows 7 and this situation will not change. I believe windows 7 will not get outdated in the average future as windows 10 is final windows version (further improvements will come as upgrades only).

Wow Slav, that sucks. What are you going to recommend for Win10 users, use a VM running Win7?

There is a good reason why Microsoft is making Windows 10 free for many of their customers... I'm an IT professional. 99% of people in IT never get a new Windows version until at least one year after release. The first year of every release is usually major bug and stability fixes, and by that point you can make an informed decision on whether it is better than the old version.
