Hi
which architecture is recommended for Windows 7: 32bit or 64Bit?
.exe files and updates are greater in size in 64bit!!

If bandwidth is an issue, then the odd application or update may be slightly larger. We are moving on more than ever to 64-bit computing, it provides some slight but necessary improvements in how the microprocessor handles operations on large numbers. That's why we moved from the 8 and 16 bit microprocessors of the past.

If you perform day to day computing you may not ever need to use 64 bit versions of things. If you have more than three or four gigabytes of RAM however a 64-bit OS will be required to handle the addressing.

I use win 7, 32 bit with 2.5 GB Ram. I have a few Chinese drivers. I'm not if I can find suitable 64 bit drivers.
sometimes Windows Live MovieMaker and Blender crash. I think using 64Bit version may fix these problems & some programs may run faster.
I think Microsoft may have better support for 64Bit architecture.
I'm not sure which architecture is better for me.

for Kubuntu I know 32bit is recommended! :confused:

64-bit has a few advantages, as far as addressable memory and drive space. Many applications are still distributed as 32-bit, but as time goes on that will change. 32-bit cannot run 64-bit apps.

64 bit is for pc with 4GB ram or 4 core cpu in my case i got 8GB ram and 8 core cpu on my laptop thats why i must use 64 bit :p

You don't have to use 64-bit just because you have 8 GB RAM; if you run 32-bit, you'll only be able to use, what, 4 GB? of it? Maybe a little less, because of the buses, but I don't know about that for sure. But if you want to employ the full 8 GB of memory that you have, then yes, you would want to use 64-bit.

in my experience, applications crash less in win 7 64bit. eg Blender or Live MovieMaker

And my hardware gets better rating in Windows Experience Index (I think for aero graphics) when I install 64 bit version.

Something I encountered when dealing with a 64 bit computer: some software is written strictly for 32 bit. In certain scenarios, such as running classic ASP under IIS, connecting to a database via ODBC, strange things can happen. IIS is 64 bit. ASP runs in 32 bit mode. To access the ODBC connection, you MUST have the connection created in both the 32bit and 64bit ODBC with the same name, because IIS is responsible for managing the connection (64bit), but ASP only recognizes 32bit ODBC connections.

There is no recommended architecture, if your preference is only to run Windows 7. If you have 64bit processor, then I will strongly recommend 64bit, as long as you have memory at least 2GB. If you have memory more than 3GB, then you have to use Windows 7 64bit. So if your favorite applications are hungry for memory and they support 64bit, then 64bit is the only way to go.

Of course. One of the causes is that in 64bit application you have to store pointers in 64bit (doubling pointer in 32bit). Many values will be 64bits aligned to make it more efficient when working with 64bits registers.

Compared to XP 64 bit, support to 64bit Drivers in 7 is really really great. Maybe you just need to add more time to hunt for the driver, or just contact your vendor for 64bit drivers.
