A page file is a special system file on your computer used for 'virtual memory'. Windows (and other operating systems) use this to make it appear that your computer has more memory than is physically installed. When you run out of physical memory, the operating system swaps portions of memory to a paging file to free up physical memory for other use.
In order to change the size of your page file, go to:
Control Panel > System > Advanced(tab) > Performance (Settings button) > Advanced (tab).
At the bottom of this tab, you will see your virutal memory information. Click the change button to change the size of your page file.

A page file is what your computer uses for virtual memory, a temporary area for your computer to run programs. Depending on your Operating system, there are several places to look to have this changed manually. Although, I would not reccomend doing it yourself if your not a advanced computer user. It is ok that its increasing, but is a indication of high memory usage.
Causes for this are programs that are eating a lot of memory (RAM) and the temporary area (page file) needs to be increased to make up for it. Increasing your RAM size can help if the system seems laggy because of various programs running at the same time.
To find out your memory size Left Click Start > RIGHT Click My Computer > Properties. Your Ram will be displayed under the computer field. (This Applies to Windows xp, in Windows 2000, Right Click My Computer on the desktop > Properties)
You can pick up ram and have installed at any Computer Store.
Another thing you can do besides increasing your RAM, is to clean out any processes that don't need to be running. Alot of users have lots of stuff running that they don't need.
In windows xp, Click Start > run > msconfig.
Click the startup tab.
Uncheck any program you KNOW does not need to be running. If you are unsure, leave it alone.

To resolve this issue, give the System and Administrators accounts full control of the NTFS volume on which the paging file is configured. To do this:
1. If you are running Windows XP Home Edition, or you are running Windows XP Professional but you do not log on to a domain, start your computer in Safe mode.For additional information about starting your computer in Safe mode, click the article number below to view the article in the Microsoft Knowledge Base:
315222 (http://support.microsoft.com/kb/315222/EN-US/) A Description of the Safe Boot Mode Options in Windows XP
NOTE: If your computer seems to stop responding while Windows is loading your personal settings, press ALT+TAB to switch to the Limited Virtual Memory dialog box, and then click OK.
2. Click Start, point to Programs (or All Programs), point to Accessories, and then click Windows Explorer.
3. In the left pane, expand My Computer, and then click a drive that is configured to use a paging file.
To determine if a drive is configured to use a paging file:
a. Click Start, click Run, type control sysdm.cpl, and then click OK.
b. On the Advanced tab, click Settings under Performance.
c. On the Advanced tab, click Change under Virtual Memory.
d. Click a drive in the list, and then note the options that are selected under Paging file size for selected drive. A drive is configured to use a paging file unless No paging file is selected for that drive. If more than one drive is configured to use a paging file, click the first drive in the list the first time that you follow these steps. Click the second drive in the list the second time that you follow these steps, and so on.
e. Click Cancel, and then click Cancel to return to the System Properties dialog box.
f. On the Computer Name tab, note the name before the first period in the Full computer name box. This is your computer name. You will need this information in steps 5 and 6.
4. On the File menu, click Properties. Click the Security tab to view the current permissions.
5. Click Add, type computer name\system, and then click OK.
6. Click Add, type computer name\Administrators, click OK, and then click OK. Note that you must type Administrators, not Administrator.
7. Click System, and then click to select the Full Control check box. This automatically selects the other check boxes.
8. Click Administrators, and then click to select the Full Control check box. This automatically selects the other check boxes.
9. Click OK.
10. If you want to make changes to your paging file options, click Start, click Run, type control sysdm.cpl, and then click OK.
11. On the Advanced tab, click Settings under Performance.
12. On the Advanced tab, click Change under Virtual Memory, and then set the paging file options that you want.For additional information about configuring paging file options, click the article number below to view the article in the Microsoft Knowledge Base:
308417 (http://support.microsoft.com/kb/308417/EN-US/) HOW TO: Set Performance Options in Windows XP
13. Close the System Properties dialog box, quit any running programs, and then restart the computer.

The paging file (Pagefile.sys) is a hidden operating system file. If you modify the NTFS permissions on a volume in Windows, the System account may be inadvertently removed from the partition. If this occurs, the System account cannot manage some system resources such as the paging file.
By default, the Everyone group has Full Control permissions on an NTFS volume. This permission might have been removed to provide additional security. Individual accounts, such as the Administrator account, may have been added. However, the Everyone group includes the System account. Removing the Everyone group without adding the System account as an individual account renders the paging file unusable.

Clear system page file at shutdown
Virtual memory support in Windows NT uses a system page file to swap pages from memory of different processes onto disk when they are not being actively used. On a running system, the page file is opened exclusively by the operating system and is well-protected. To ensure that any sensitive information from process memory is not left on the hard drive and thus not available to a user booting the PC with another operating system, apply the following Windows NT / Windows 2000 / Windows XP registry hack:
Key: SYSTEM\CurrentControlSet\Control\SessionManager\Memory Management
Note that this protection only works with a clean shutdown. The ClearPageFileAtShutdown is part of the normal shutdown process when this value is set. Valuable for shared PCs or if you have something very valuable needing protection.
