Always be careful when editing the registry since any changes are made instantly. If you want to clear the history of searched for items you will need to edit the registry. You may or may not want this history to be kept on your computer for whatever reason. One thing you may have noticed that it keeps a history of your past searches and you may not want that search history to be kept. Finally your search results will be displayed in the main window along with other information such as the path to the file and so on. Then you will notice a green status bar going across the top of the window as it searches. With newer versions of Windows you type your search word(s) in the search box in the upper right hand corner of Windows Explorer.
That is up for debate and up to you to decide once you use the new Windows search method. Many people don’t like the 'new' way and say it doesn’t work as good as the older XP style of searching. The way you search for files and folders in newer versions Windows is different from the way you do it in older versions of Windows where you used the search companion to help you find your files.
