One of the most annoying things of Windows XP is that the search became much slower than windows 2000 and when using the search tool to find text inside a file, windows does not search all file types.
E.g. it does not search files with extension of .log .pas .exe.
You can enable this feature and make Windows XP search all file types for the text that you specify. Before following the procedure make sure you have the latest Windows patches installed.
The procedure to turn ON indexing of all file types:
1. Click Start, and then click Search (or point to Search, and then click For Files or Folders).
2. Click Change preferences, and then click With Indexing Service (for faster local searches).
3. Click Change Indexing Service Settings (Advanced). Note that you do not have to turn on the Index service.
4. On the toolbar, click Show/Hide Console Tree.
5. In the left pane, right-click Indexing Service on Local Machine, and then click Properties.
6. On the Generation tab, click to select the Index files with unknown extensions check box, and then click OK.
7. Close the Indexing Service console.
Now search will search withing all file types, even if you don't use the indexing service of windows.
