This article shows how you can check a personnel computer can run 64-bit window operating system. 64-bit computer can handle large amount of data then a 32-bit system if 64-bit OS installed. 64-bit also refer to number of bits can travel between processor and memory RAM at a time. Why i would like to run 64-bit Window7 instead of 32-bit Windows7. The reason may be different for every one. I have 4GB ram in my Asus laptop but Window7 only showing 2.93 RAM is usable.
