I can't download flash player, opera browsers or avg antivirus or any software I want and a message comes up that says I need to get that software at the windows store. I try opening Netflix and it does not work of the site because I need Silverlight player which also don't let me install. I was able to get Netflix on the store but not any other software I want. I want to install windows 7 but wondering if its going to work. I know I might loose the touch screen and probably sound but what else are the down sides?
