Now that Black Friday offers are sinking in, some of which are being extended into the holidays. Be it that laptop or desktop that you want, the issue always remains do I get 32bit or 64bit OS.
Times have improved since Windows Vista, where 32bit and 64bit were two worlds apart. They are almost similar, but the more technical people can deal with that.
The good news is that Windows 7 (Home Basic and above) supports 4GB RAM out of the box, without any additional configuration on your end. Just install and it will run.
So unless u need more than 4GB you can stick with your 32 bit Windows 7 install
