Speed up Windows XP

Windows XP keeps a record of all files on the hard disk and will regularly index them to improve search speeds by default.
Unfortunately,this can sometimes lead to slower system performance.If you don't use the file search feature very much,or can live with slighly slower fies, you can disable XP's indexing feature.
Open My Computer,right-click on one or your hard disk icons,then select properties.Uncheck the box to "Allow indexing service to index this disk for faster searches",then click on Apply.
A new window will pop up asking if you want to apply changes to all folders and subfolders. Click OK.
If your hard disk contains many files,it can take a few minutes to turn off indexing.
