Windows 7: 32 bit vs 64 bit Comparison

Plus, as in the past, we end up outgrowing the OS limits. In this case, the prior OS versions, memory sizes kept increasing. We use to be able to run Windows 95 with 64 megs of ram, and kept pushing it up to 512. Win98, we could run at 128, but pushing up to a gig. Windows XP, we could run at 256, but now we push up to 2 gigs to run reasonably.

I say 2 gigs, even though we have others who pushed it to 4 gigs or higher. The simple fact is, back in the day, coding required assembly to do a fair deal of things with as tight as code as possible. With Visual .net Programming, or high level coding, the old way of tight coding has become less and less, and at the same time, more and more 'bloat' in programs and the need for memory. Not just in OS, but in general applications.

Another good example is this:

At my place of work, I inherited the legacy of another group's incompetent IT planning. 20 users, about half of them running on 5 to 7 year old machines, most of them running with 512 megs of ram. Lots of complaints of performance. Performance impacted due to running lots of program, but no plan or budget to get more memory to improve the situation.

When my division's IT department got absorbed by another division's IT, and the issue of performance came up... One of the users was given more memory, per my recommendation. Suddenly, performance increased. Reason - I diagnosed the issue of heavy disk activity == Virtual Memory swapping. Virtual Memory swapping due to low memory and programs like Microsoft Office's Access, Outlook and Word running when before, they would only use Access on occasion and Word and use another client for mail.

A prime example of poor planning on the previous IT department on skimming on certain things. But eventually, the necessity to go past 4 gigs of RAM will come mostly due to computer usage habits which will also mean people will be having more programs running or programs that will eat up more memory over time. Performance is directly related to Memory as well as CPU, and as more and more programs decide 'Hey, I want more memory...' The more impact the system suffers due to having to virtual memory swap to accommodate the lack of memory.

Now that we have Flash player square (Flash for x64) there is little reason to stick with x86 unless your machine just will not accommodate x64 or you have a piece of software that is not compatible. Finding drivers (even legacy drivers) has become much easier the last few years and there are sites dedicated to x64 only.

X64 browsers are slightly safer and have tested out slightly faster than x86. Still it is a personal choice that everyone must make for themselves.

The key will work for either x86 or x64. But only one instance, your choice. You can can change from x86 to x64 or visa-versa at will but it will require a clean install, not an upgrade.

As bobtran said, you can install EITHER version, but not BOTH.

UPDATE: I added this information onto the front page.

I do wonder about the legality of running both on the same computer but not simultaneously? He could dual boot if it is legal ONLY.

Also not sure if it is OEM, retail, or other.

Good question. I am going to assume it is not technically legal, but I am not sure that you would ever get caught...

It might sense that the key was active on the other install when he tries to activate it though.

It IS possible to dual boot both versions or install as many versions as one wants on the same PC. It's not legal though so I could not possibly condone or encourage it.

I run with Win 7 Pro X64. I installed Win 7 Pro X86 under Oracle VirtualBox. After 30 days it expired and would no longer function and I could not activate it, so the answer is no, you cannot legally do this. It's a shame as it would make great test environment for doing research for posts here and on other forums.

I wonder why t's not allowed, since it would always be running on the same computer.

I think MS probably considers your purchase authorizing 1 active activation, so in this case, having both a 32 and a 64 bit version running at the same time would be trying to double dip. On a virtual level, it might not really tell if you are trying to run it on the same box versus another computer. Of course, not knowing how they can readily identify the difference, I think it is just working the way Adobe products use to work in a Mac environment, where it sees another machine within the local area running the same product key activator.
