Hello, I've been using Windows 10 for quite a while now. I don't recommend it just yet, although there are many improvements in terms of design, there are many technical issues that prevent the OS from working fluidly. So far, every application and game has worked just fine, there were no compatibility issues. The problem is the OS itself can be a unresponsive at times, explorer.exe crashes, etc. It's a little messy at the moment. I would wait for the official release, which is around July 29.
