The path to modifying virtual memory is as follows:
Computer (right-click) Properties--Advanced system Settings-System Properties (Advanced)--performance (set)--advanced--Virtual memory

1) Set the C drive to "No paging file", or customize the file size, click the "Settings" button
2) You can create a virtual partition in a different space, click the "Settings" button
