OS and a Browser that run's in Windows OS's. The Chrome OS is processor specific on chrome laptop devices. Using Windows either windows 7 or Vista you can run many different browsers. Typically flash may be needed to run some streaming video. I have multiple browsers installed (IE, Chrome, Safari and Opera). Sometimes when I watch some videos i will get a message that the video will work better with Chrome so I just start Chorme up and watch it in Chrome. I prefer IE but have used all the others at times.
I am new at this, so bear with me. I am trying to decide if I should change over to Google Chrome. I currently have two laptops. One is an HP with Windows Vista and the other is a Dell with Windows 7. On several sites I visit, they recommend using Google Chrome if I have trouble with things like streaming video. What, if any, is the benefit of changing over to Chrome? If I decide to go that route, what problems would I run into changing over, and should I remove Vista and 7 from my system once the changover is complete? Also, is this something I should do myself, or should have someone with more knowledge do the work?
