Win 7 version question

By puppybreath ·
I just received a new laptop loaded with Win 7 Home Premium 64bit. The laptop has 3 GB RAM.

I have a corporate license for Win 7 Professional 32bit.

I've read that the 64 bit version should have at least 4 GB of RAM to run efficiently. So it appears that the laptop has a handicap from the start.

If most of my work is with older business software and there is no need for any heavy duty processing like CAD, gaming, or photo manipulation, am I better off loading the 32 bit OS?

From what I've read, it looks like the 64 bit OS won't really help speed up my older apps, but installing the Professional edition would give me additional functionality.

edit: had wrong version names listed

the only difference you will notice

by .Martin. In reply to Win 7 version question

is compatibility.

some older programs don't like the 64-bit version of windows, and won't run.

as for performance, you don't really notice any difference when you only have 3GB of RAM

there is only one Premium version. Premium = Home Premium.

That should have been Professional 32 bit. Sorry about that.

So the question is whether I really lose anything going back to a 32 bit OS based on the types of apps I'd be running and the hardware I'd be using.

Or do I gain enough by going from Premium to Professional to make up for anything I'd lose going from 64 bit to 32 bit?

Ah. A lot. Depends on whether you use those features.

Ask your IT guys why they did that. They can do pretty much whatever, and the license sticker on the machine is then more or less meaningless.

Biggest difference 64/32: Do you have 4GB or more of RAM installed? Can't really use more than 3-ish GB with a 32-bit OS.

Do you run any apps that are 64-bit only?

there are no IT guys <grin>, just the boss. Told him I needed a new laptop and spec'd out what I preferred but this is what he ordered.

Only 3 GB of RAM. Don't use any apps that are 64 bit only, so I guess I'll switch to the Professional edition. I think that sooner or later I will need both the remote access and the XP mode so that seems to be my best option.

I'd put it the other way around

If you have/want/need more than appr 3 GB, then you need a 64-bit system in order to be able to address all of it.

The 64-bit version enforces some security things, for instance DEP (Data execution prevention). Raised security may be good, but this means that some of your older software may not run, it it doesn't obey the rules.
For some older hardware, you may not find suitable drivers for a 64-bit platform.

I guess it will take some time until we get PC programs specially created to squeeze the maximum power out of a 64-bit system. (Servers are a totally different topic).

A good things you get in a 64-bit environment is the better possibility for virtualization, where different applications can be better isolated from each other, I guess. (Need to read more about this, though.)

Anyway, if you want to use remote desktop and xp mode, then I think you can securely downgrade to the corporate license.
