If you often work with large file sizes-large and takes a lot of memory (eg video editing) of course Windows 7 64-bit will be the best option because it will give better performance compared to Windows 7 32-bit. As we all know Windows 7 64-bit has a memory support up to 192GB, while the Windows 7 32-bit only 4GB for maximum performance. Another advantage of Windows 7 64-bit is in terms of security, more secure than Windows 7 32-bit, because the drivers Windows 7 64-bit must be fully certified by the vendor of the hardware makers, so it is very difficult to be infiltrated by malicious programs.
