Sorry, I should have re-specified in my reply that we're discussing x86 versions only. The 4GB question is a little complex, since 36-bit addressing with PAE has been available in processors for some time. However, MS does not use PAE in 32-bit versions of their client operating systems to allow you to use more than 4GB; that's reserved for their higher end Server SKUs. Soren insists that you can use more than 4GB of memory in a 32-bit client MS operating system, and that's the current discussion.
The x64 editions absolutely can use more than 4GB. The Ultimate Edition W7 SKU can use up to 192GB of memory.
