I turned on my PC, launched google chrome from the start screen, and it had windows 8 mode turned on, also my search engine was swicthed to yahoo, I did not do this myself, I never go into the settings place. Then I tried opening Google from the desktop and it just brought me back to the windows 8 mode. Then some time passed with my browsing. And eventually I closed google, then maybe 20 minutes later I opened it again and everything was back to normal, it changed itself back to desktop mode, yahoo was still set as my defult browser but I was able to change it back. Any ideas what happened, why it was running in windows 8 mode then changed back? All by itself without any action from me?
