As to the pagefile.sys that is in use by the virtual memory if you have plenty of ram you can turn off or at least reduce the amount set aside:
- click start
- right click my computer
- click properties
- click advanced (tab)
- under performance click settings
- click advanced (tab) under virtual memory click change
here you can change the space available for each drive by choosing the custom button then entering the amount you want
or if ya got lotsa ram choose the no paging file either way make sure to click the “set” button when you’re done
