Google desktop search was formerly released as a preview in 2004 that uses the same algorithm as a Google search uses that made the internet search engine fast, popular and accurate but at the same time it makes windows slow.

The key to such fast and accurate searches is the construction of index information that is stored on your computer. This is the same approach that many other search programs use in building their search engines but at the same time it slows the operating system.

Google desktop search tool indexes the content on WebPages that are previously viewed with internet explorer, email sent through outlook, AOL instant messenger, text files or any other Microsoft office documents.

Google desktop search tool searches for the name and type of the file not the internal content like picture, portable document format files etc. and also recognizes the files created by the unrecognized programs.

As Google desktop search tool slows down the operating system, a new technology is developed that changes the way information is being stored on the computer.
