I am still hanging in the past with windows 7 since after the 6 computers 4 currently I have owned I have yet to have to do a restore or re-installation of win 7. So far performance is still pretty darn close to windows 8 so I plan to stay with it until windows 9 or something.
At least it is not like running windows XP sure it was better then win 95,98 etc. But i was having to do a fresh install on at least one of my rigs every 3-6 months. At least with windows 7 I have not had to do a fresh install in at least 5 years and have not had any compatibility issues YET, and I hope to never have any.
