During data processing some operating systems use the hard disk as memory, called virtual memory. During processing, operating system transfers some data and programs from RAM to hard disk and reloads again when required. The data or programs are stored in hard disk in temporary file called the swap file. This technique of swapping data between memory and hard disk is called paging. Operating system spends a lot of time in paging process, instead of executing the application software. But the problem is that while working you use different software programs on computer and page file may contain your confidential information or stored in non encrypted format. To reduce this risk, you can set your computer to clear out page file automatically each time you shutdown your computer.
Perform the given steps to set your system clear page file automatically:
To enable this feature, you will need to be logged into your computer with administrative rights.
First click on start button to open control panel and then click here on "Administrative Tools" option.

Now small dialog box will appear with options, "Enabled or Disabled" the page file.
Select the "Enabled" radio button to set clear page file each time you shutdown computer.
