Benefits Of Windows 7 64-bit Operating System

Windows 7 makes everyday tasks faster and easier, to make our PC work the way we want it to, and to make it possible to do new things. And that's exactly what its doing. And now, we have to make the most of the new 64 bit OS.

When deciding to move up to a 64-bit operating system, you should first consider what 64-bit gets you. Knowing what software runs on 64-bit should influence your decision; you will see no advantage if you are running 32-bit software on a 64-bit OS. You also lose the ability to run 16-bit software, which shouldn’t be a problem unless you rely on older software, such as old work software or home-made packages you haven’t yet updated. 

What Does 64-Bit Windows 7 Gives You:
More bits gets you access to more memory; the processor inside your PC communicates with your system memory (RAM) with numeric addressing. Thus, the maximum amount of memory a 32-bit processor can address is 4 gigabytes. Newer 64-bit processors— not to mention the 64-bit operating systems that run on them—can address 17,179,869,184 gigabytes (16 exabytes) of RAM. 
Windows NT, released in 1993, was Microsoft’s first fully 32-bit operating system; however, it took eight years before the platform, which had since evolved into Windows 2000 and then XP, became mainstream. (Yes, Windows 9x ran 32-bit applications, but it was a hybrid OS that ran on a 16-bit DOS foundation, which was one of the reasons it was so unstable.) 64-bit Windows became a reality in XP, and Vista was Microsoft’s first serious attempt to make 64-bit computing mainstream. I am sure more people will use Windows 7 64 bit because of the increasing demands for more RAM. The question is: how mainstream is 64 bit?
How Compatible / Mainstream is 64 bit?
While 64-bit 7 can run most 32-bit applications without a problem, it’s not compatible with 32-bit hardware drivers or 32-bit utilities like Windows Explorer extensions (e.g., context menu add-ons.) This means you need a native 64-bit driver for every device on your PC; finding support for all your hardware may be a bit of a challenge, at least on older computers.
Performance Increase:
Now, 64-bit software running on 64-bit Windows has been known to run as much as 10% faster, which illustrates the other reason—aside from memory addressing—that people find 64-bit 7 alluring. Just be prepared for lackluster industry support, at least for the next few years until Microsoft releases a 64-bit-only OS.

Windows 7 System Requirements

As the current version of Windows 7 is still not the final version, the system requirements are subject to change. However, the current minimum system requirements are as follows:

  • 1 GHz 32-bit or 64-bit processor
  • 1 GB of system memory
  • 16 GB of available disk space
  • Support for DirectX 9 graphics with 128 MB memory (to enable Aero theme)
  • DVD-R/W Drive
I’ve tested Windows 7 with 512MB of RAM and found it to work well; however, I do not recommend running with such low memory – unless you really have to.

Have you not tried 64bit OS before? Well, the best approach is to start by throwing away preconceptions from earlier Windows versions and approach the new OS with an open mind.

Where most Branded PC Manufacturer will tell you that 4 gig is the max but don't tell you that the OS will only use 3 to 3.5 gigs. This is the limitation that is built into the 32 bit system. When the 64 bit system came out, back in XP Pro 64 bit, there was not a lot of software for the everyday user. Now as technology and software has improved so has the demand for 64 bit systems for the everyday users. It's just a matter of time before the 32 bit system is phased out completely, like the introduction of the music disc which made the cassette obsolete. It's just better, same for the 64 bit system. There is nothing that says to can't go from the 64 bit to the 32 bit system. When you get your 7 DVD OS, it has both versions of it on the disc, you just have to tell to use the 32 bit when you install the OS.

Actually the retail packages come with two discs, one for 32 bit, one for 64 bit.

Just use the DVD with the version of the Windows 7 you want to install.

I would still install the 64 bit version of Windows 7 though, its better than the Vista 64 bit version and faster too.
