So I just learned another HUGE reason to get windows 7. I realized I'm running a 32 bit XP operating system with 4 GB of RAM. My OS is only recognizing around 3 GB out of the 4 GB total ram. For any of you that are running 4 GB or more, make sure you have a 64 bit OS or your wasting RAM.

Keep in mind that it doesn't matter if it's Xp, Vista or "7"; 32 Bit OS will USE up to 3.25 GB of RAM I believe. 64 Bit in XP, Vista or "7" will utilize as much RAM as you throw at it.

Yup.. I did not know that until today. I've been messing with overclocking and realized that I was using 80% of my RAM.

I would love to use a 64 bit OS but I can't because of VPN software. Cisco and Aventail both refuse to make a 64 bit client. Cisco has their anyconnect but it doesn't work for all cisco networks. I could use a virtual machine but then what's the point?

I'm sitting here on a computer with 8GB but I can only use 3.24GB.

I switched all my computers to 64 bit when I upgraded to Windows 7 this time. Most of them had at least 4gb of memory. I have had no issues because most 32 bit software works within the 64 bit OS. I am also finding slowly but surely many of the programs I run are now being offers in a 64 bit version.

Yeah, SAP's client even runs on 64 bit but Cisco and Aventail have no plan on allowing their stuff to run on 64 bit. As of now anyway.

4GB of RAM for the 64bit version of Win 7 is almost minimum.

I think the point is that many have machines with 4gb, but their 32bit OS never allowed them to make full use of it. Now with 64bit Win 7 with all its memory tweaks 4gb is a highly acceptable amount of course depending on what you are doing. I really love how Win 7 gives you your graphics memory back when you minimize a program. It handles memory very wisely!

I've definitely encountered some issues with the 64 bit OS. Took me all day yesterday just to get Dragon Age to install. Windows 7 is a sweet OS. Hopefully software will catch up quickly.

A corollary to all this is don't try to install 8 or 16 GB of RAM without checking to see if your motherboard will even read it. It's not just a software limitation--neither of my boxes can even accept more than 4 GB total.

I've noticed that Windows 7 segregates programs based upon 64 and 32 bit capabilities. My only complaint so far with Windows 7 is the "programs" section under the start menu. I find that a lot of programs I install don't show up there and I haven't figured out how to correct that yet.

You know you can add your own link, right?

When I click a tab that says "all programs", I expect to see "all programs". I don't like having to manually insert things into what should be everything. Again, it's a small complaint compared to the overall, but it's still a complaint. For the most part I've been very impressed with Windows 7 and am very glad I had the opportunity to install it.

It has to do with the number of integers that a 32bit OS can use to store memory addresses. 32bits only gives enough memory addresses for about 4 gigs, but you still have to subtract stuff like video memory, and some stuff that Windows reserves, so you never get the 4 full gigs of RAM. That's my understanding anyway...

The programs that you want access to immediately pin them to the task bar.
