1. Click Start, point to "My Computer", right click and then click Properties,
2. On the Advanced tab, in the section entitled "Performance"click Settings,
3. In the dialog box that appears select the Advanced tab, then click Edit in the Virtual Memory section,
4. Tick the "No paging file" and confirm by clicking Set, and then click OK each time. Be careful, make a note defines the parameters for your paging file to perform this step in order to re-enter at Step 7.
5. Restart your computer so that the new parameters are taken into account (this will effectively delete the swap file)
6. Run the tool "Disk Defragmenter" on the drive where the file was this exchange that the fragments created by the pagefile should be reorganized so contiguous.
7. Recreate the swap file (see step # 1-3) on the drive home by giving the default settings that you noted in step 4. Click set, finally click on OK every time.
8. Finally restart your computer.

Note : there is another way to defragment the paging file in a simpler and faster, why just use a utility called PageDefrag developed by Mark Russinovich of Sysinternals. Another advantage is that it provides PageDefrag allows beehives defrag files loaded in the Windows registry (default, SAM, SECURITY, software and system folder% windir% \ system32 \ config) and log files of events (AppEvent.Evt, SecEvent.Evt SysEvent.Evt and also located in the% windir% \ system32 \ config). You can donwload PageDefrag from the official site.

Technical Terms :

Swap -
Virtual memory is a technique that expands the physical memory (RAM) to a mass memory (hard disk, USB stick, ...). This technique is called paging.

Partition -
A partition is a division of a logical or physical disk drive. By analogy it is a sort of container in which to find the files and folders.

Defragmentation -
Defragmentation is a process that involves bringing together fragmented files on a hard drive for contiguous rearranged in order to reduce the displacement of the read heads to reconstruct the parts of a file.
