So a dell vostro running windows 7 in 32bit tells me that the machine is only using 3.9 of the available 8 megs of ram

If i installed a 64bit version would that then use more of the ram?

Does this mean that if I leave the 32 bit version I might as well remove 4 meg of ram as its "not being used anyway"?

You could always use the unallocated memory as a RAMDrive.  I have used RAMdrives but while I never used unallocated/unaddressed memory, there are products out there that suggest it's doable.

Install a 64 bit OS. W10 will be out in a few weeks, I'd wait for that.

It will because its 64 bit.

32 bit has a 4GB "limit"

Its not a MS limit, its just the way it is without going into detail :)

Also, if windows 10 is like 7/8 and you're relying on upgrading your current install to Windows 10, you will likely need to select the custom\advanced option when installing Windows 10, otherwise I think it may (can anyone confirm?) just upgrade to the 32 bit version of Windows 10 (why on earth are they even planning to offer a 32 bit version?)

64 Bit system's can handle an almost unlimited amount of memory (millions of Terabytes)

Software wise - Windows 8 supports 128GB in 64bit, Windows 8 Pro supports 512GB RAM in 64bit

This will be the same in Windows 10.

You will not be able to upgrade from 32bit to 64bit, you will need to fresh install the OS.

Windows 10 will be a free upgrade so just wait.

Just to throw a spanner in the works and confuse you, sometimes your chipset will not utilise the entire ram you install after market as some chipsets and cpu's only allow a maximum amount of memory, even though you can buy compatible ram sticks with higher density (say you install 4x8GB dimms but system only allows max 16GB RAM).  Inversely many manufacturers also specify maximum amount of ram that the system can handle, but it is actually capable of taking more when higher density dimms are released (they specify 16GB max but later on installing 4x8GB dimms gives the system 32GB).

Bottom line?  Fresh install Windows 10 64 bit when it is released, you will be able to download an ISO from Microsoft and use Rufus tool to flash it to a USB.

Still hasn't worked out he's saying meg and not gig. It would have to have been around 15 years ago since I saw a 8mb memory stick.

You are still limited by the CPU and it's packaging, effectively the number of address bits that physically come out of the chip.

Example below is limited to 32GB of RAM.

Oh, can we do that with Windows 10? I have a windows 7 laptop that's 64 bit capable but it came with 32 bit; I'd like to upgrade it to 64 bit Windows 10 so it can use its full 4 gigs of RAM instead of 3.whatever.

AFAIK you would need to clean install to go from 32bit to a 64bit version of windows. Pretty sure you can't do an upgrade and never have been able to.

If you mean switch between 32 and 64bit on a computer then yes it is, though you might have to call MS to get activated. I have done this once, though it was in the Vista days. Pretty sure nothing has changed about this though :)
