Windows 7 64 Bit
We are in the process of reviewing the 64 Bit version of Windows 7.
64-bit systems offer direct access to more virtual and physical
memory than 32-bit systems and process more data per clock cycle,
enabling more scalable, higher performing computing solutions.
There are two 64-bit Windows platforms: x64-based and Itanium-based.
Today, 64-bit processors have become the standard for systems ranging from the most scalable servers to desktop PCs. The way to take full advantage of these systems is with 64-bit editions of Microsoft Windows products.
x64 solutions are the direct descendants of x86 32-bit products, and
are the natural choice for most server application deployments - small or
large.
Itanium-based systems offer alternative system designs and a processor architecture best suited to extremely large database and custom application solutions.
Windows 7 and Windows Vista also come in both 32 and 64 bit versions..
There was speculation that Windows 7 would only be 64 bit but based on the release of the Beta, that is not the case. More to come later..
New! interesting article about Windows 7 64bit from PCWorld
Interesting article from w7forums.com.
Not only are there going to be several Windows 7 editions, but you will also need to decide if you are going to run a 32 bit or 64 bit version of the operating system. If your CPU is more than a few years old there is a good chance that you can only run the 32 bit version of Windows 7, however if you have a modern processor you may have to decide between each version.
The 32 or 64 bit architecture refers to the memory address length that can be referenced by the processor. This also has an impact on the maximum amount of memory that can be utilised, which is 4GB for a 32 bit CPU (but in reality the maximum accessible ram is closer to 3.4 GB due to other hardware allocations).
Having a 64 bit OS doesn't automatically make all applications faster because much of today's software is written and
optimized for a 32 bit era. You'll need software specifically optimised for 64 bit processing to take advantage of any speed improvements. Fortunately, many games are already including such enhancements.

You may think that using a 64 bit OS for a 64 bit processer is an obvious decision, but it is not so straightforward. Introducing a new architecture will cause new compatibility and driver problems that wouldn’t exist under the old 32 bit version.
Pros and Cons of a 64 bit system:The conclusion? Well, it depends on what you use your system for. If you have a 64 bit capable CPU but use older hardware, it would be safe to stay with a 32 bit version for the time being to ensure that you don’t need extra upgrades.
- You can address much more than 4GB of memory, which is ideal for avid gamers, CAD, video editors and heavy multi-taskers. However, any 32 bit software you use will still be restricted to 4GB memory – you need a 64 bit CPU, OS and applications to take full advantage of the extra RAM.
- 16 bit applications will no longer run. Although this is unlikely to be a problem, if you use very old software (from the Windows 3.1 days!) then it will not work under a 64 bit OS.
- Existing 32 bit drivers no longer work. If you have older or poorly supported hardware you may find that it can no longer be used. Got a 7 year old scanner that just about works in Vista? You may not be able to get it working in 64 bit Windows 7.
- Unsigned kernel-mode drivers no longer work. Along with the issue above, the inability to run unsigned kernel mode drivers will cause problems for old hardware. (There is reportedly a way to bypass this check).
- Running some 32 bit applications on a 64 bit OS could actually be slower. The additional overheads in running 32 bit software in 64 bit mode could cause a slight degradation in performance. It will take some time for 64 bit software to become the norm.
If you’ve got the latest hardware and drivers are available, then it may be worth while taking the step up to a 64 bit OS. If you regularly work with resource hungry applications that are 64 bit optimized (such as video editing, CAD and image packages) then it would be especially beneficial to be able to work with over 4GB of RAM amongst the other improvements.
