A couple of final limits related to virtual memory are the maximum size and number of paging files supported by Windows. 32-bit Windows has a maximum paging file size of 16TB (4GB if you for some reason run in non-PAE mode) and 64-bit Windows can having paging files that are up to 16TB in size on x64 and 32TB on IA64.
Although contemporary 32-bit PCs were theoretically able to address up to 4GB of RAM, memory was expensive, and a high-end system may have come with only 256MB installed. A reliance on virtual memory was a fact of life â hence the rule of thumb that you should install as much memory as you can afford.
