Window 7 came with my laptop,CQ50. I later changed the OS to Window 8. I later discover that my laptop is selective of software installation. The painful part is that, softwares that I installed effortlessly when I was on Window 7 will refuse to get installed on my new Window 8 OS...it sucks a lot as most important softwares won't just get installed. Please I need computer gurus suggestions and tips. Thanks.
