Windows 7 64 bit and Windows 7 Starter 32 bit
 
 

Have just read this to help me decide which version of Windows 7 to install on a Vista laptop. Hmm. Seems like my laptop is borderline! I have just bought a used Sony Vaio VGN-CR31S/L. It has a core 2 duo processor and takes a maximum of 4gb ram. So ram wise I'm on the max for 32 bit and quite low on 64 bit I guess. I am tempted to go with 64 bit, but on the Sony support webside, all the original Vista drivers are only available for 32 bit. They do have windows 7 drivers in either 32 or 64 bit. I believe Windows 7 installs most of the drivers automatically, but this model laptop has some specific function keys, that I would need to download the software for. I have read the other post on here about how to make Sony function keys work after upgrading to Windows 7. But am not sure whether that now limits me to 32 bit or not. It would be nice to be able to use all my 4gb of ram in 64 bit. On the other hand, I guess 32 bit would be fine. But I quite like the idea of being on 64 bit as I am wondering how long it will be before 32 bit becomes extinct! What does anyone think?

It's ok - I think I need to stick with 32 bit as the additional sony drivers required after clean install, are only in 32 bit (from the post about extra sony drivers needed to make function keys work).

According to this article the maximum RAM for Windows 8 is 128 GB and 512 GB for Professional and Enterprise editions.

But in the real world the limit will usually be that imposed by the hardware.

*86

Why is 64 bit *64 but 32 bit *86 ?

The reason is historical.
x86 refers to the series of Intel processors beginning with the 8086 and continuing to the modern, even they no longer use that numbering sequence. These were the the processors in use when the first 32 operating systems were introduced. 64 bit systems do not have this long history and are simply referred to as x64.
