You mean update windows 7 first? I actually upgraded yesterday morning and the did the full wipe from within windows 10. I noticed a pretty significant improvement in speed from my laptop so that was a plus! Only issues I had was it briefly got stuck on one screen while updating, but I found a solution online and then once it was up and running my display drivers didn't load properly so the screen was kind of jacked up. But I got that corrected and everything seemed fine since. I forgot to back up TWS to their server so all my quotes and everything I have to start over with as well as settings etc. That was a bit frustrating to realize.
