Windows XP keeps a record of all files on the hard disk so searching for files is faster, but, it is unnesecary if you do not
search for files on your hard drive much, and will slow down other file operations, such as open, or close
Open my computer
Right click your hard drive and select properties.
Untick the "Allow indexing service to index this disk for faster searches," box at the bottom.
A window will pop up and select apply to all folders and subfolders, this will probably take a minute or two for the changes
to take affect but then you should enjoy slightly faster performance
