Also tried Windows 8, but went back to Windows 7

I purchased a Sony Vaio laptop, that was "Windows 8 Ready" that had Win7Pro 64bit installed. When the time came I used the option to pay for a low cost Windows 8 Update.

After months of problem after problem (the supposedly compatible graphics drivers weren't so couldn't access GPU which messed up photo editing/graphic works, couldn't copy/paste files or move them from one directory to another, Updates wouldn't) , I ended up putting Windows 7 back on and things have been working fine. So yes, you can, you just have to get an installation disc for Windows 7.

What Microsoft needs to to is maybe put out a version of Win8 that is for desktops/laptops that aren't touch screen, because that tiled screen/touch interface is of no use to me and many others.
