You can get a 32 bit version of Windows 7. I would think about drivers before I upgraded.

Just because the OP does not come back in 3 or 4 days to reply, does not mean he will not come back and reply.

There is no reason to use 64 bit unless you have more than 5 gig ram and a ton of hard drive and all your apps are known to work and all your drivers are fully certified to work.

1/3 of highway deaths are caused by drunks. The rest are by people who can't drive any better than a drunk.

4 GB, actually. It depends on your hardware and drivers, but you typically only see 3.5GB of your 4GB on 32-bit platforms.

Also, I'd counter there's no reason not to use the 64-bit version if:
- You have the RAM for it
- You have the drivers
- You don't run any Windows 3.1 applications.

32bit Windows 7 on older Vista machines if Windows 7 compatibility test shows no issues and you download Windows 7 drivers for you system from the manufacturer.
64bit Windows 7 on all new machines except 'budget' machines.

You have to be a little bit crazy to keep you from going insane.

I have said this before. It is like putting chrome on a junk car. It may look better or you may feel like it is better only.

For some odd reason there is a completely false sense that somehow 64bit is better or faster. Nothing could be farther from the truth. It is not faster and it is not better in any way. It simply has a limited ability to access more possible ram. The problem is very few programs are even written to allow that ability
Then you may end up on this forum asking why this or that doesn't work.

So, exactly what could you possibly do on a laptop that would require such need of ram? After all that is the on value to the 64 bit. An what application do you have that can access more than 2g?

Windows 7 system requirements

If you want to run Windows 7 on your PC, here's what it takes:

1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor

1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)

16 GB available hard disk space (32-bit) or 20 GB (64-bit)

DirectX 9 graphics device with WDDM 1.0 or higher driver

As you can see. You will loose 1G of ram so that is way I said more than 5 gig.

I agree that companies are being forced to provide 64 bit versions on systems they know don't fully support any of the features.

Remember, it ends up being the ability to address more memory and nothing more. Problem is that every program and the OS take up two 32 bit words instead of one and it generally could take up to twice the memory to run.

It doubles* the address pins, giving you 16 Exabytes of address space.

Also, x64 versions of Windows run x86 programs. An exception would be programs that intentionally disable themselves if they're running on x64. (Buy the more costly build today! Pressing that "Compile for x64" button is worth $80 more! Honest!)

You will loose 1G of ram so that is way I said more than 5 gig.
Wait, what? Do you think Windows occupies some magical not-memory portion of memory, and thus doesn't have to share the same memory address space as everything else?

Also, some random guy's test shows only a 77MB difference in memory usage between builds. Obviously your millage may very, but it's probably closer to the truth than Microsoft's marketing. (Paradoxically the fewer 32-bit applications you run, the less memory Win x64 itself needs to use.) But that's why I said if you have the RAM for it. 3 GB should be plenty. With 4 GB, x64 should be mandatory.

Problem is that every program and the OS take up two 32 bit words instead of one
No it doesn't. x64 still uses the same x86 variable length instruction set. Window's data types' size remains constant across platforms. This is why running 32-bit applications on a x64 OS is a largely pain-free experience. The increased memory requirement comes from a possible need to have two versions of the same DLL loaded: one x86 binary, and one x64 binary.


* Limited now by your OS and current hardware. Currently, Win7 allows for up to 192 MB of RAM. The virtual address space is split at 8TB/8TB for Kernel/User addresses, instead of the 2GB/2GB or 1GB/3GB split for x86. (source)

I have built now 4 computers with Windows 7 64bit (3 Home, 1 Pro) and 4GB RAM and two of them with distinct video cards show up as a full 4GB available memory and only the ones using the onboard or onchip graphics (business/office systems) dedicates some of that memory to graphics, not to la-la land. While Windows 7 needs more memory than XP does, and 64bit does need more memory than 32bit to operate properly, I doubt that 64bit uses an entire GB loading itself into memory and ties it completely up. I find Windows 7 64bit runs very well on 4GB of RAM for my needs though for someone using Photoshop or Autocad regularly, I would recommend 8GB to speed up some processes by holding larger images in memory. For those doing video editing or creation, even more memory might be helpful. Also, Most systems benefit from from Dual Channel (or Triple Channel) memory, and from all memory locations being equal size and type, so 5GB potentially could operate worse than 4GB (2x2GB).
