Your computer has two types of memory, Random Access Memory ( RAM) and Virtual Memory. Give it a try and let us know how you make out in the comments below. If your system has 16 GB or more of memory, you can give this Virtual Memory calculation a try, but you might find that letting Windows automatically manage the paging file will work. The calculation contained in this article is for Windows computers that have 8 GB or less of memory. When I started working with Windows computers in the 90s, the measurement of memory was Megabytes ( MB), now it's Gigabytes ( GB). Optimizing Virtual Memory in Windows has always been an easy way to fine-tune the performance of a computer.
