Searching for content inside pdf files in Windows

What a misery Windows operating system is?

By default, the pdf file contents are NOT searched, you need to turn this feature on! Here is how to do it in Windows 7:
1.   Open Indexing Options by clicking the Start button, and then clicking Control Panel. In the search box, typeindexing options, and then clickIndexing Options.
2.   Click Advanced. If you're prompted for an administrator password or confirmation, type the password or provide confirmation.
3.   In the Advanced Options dialog box, click the File Types tab.
4. Check "Index Properties and File Contents".
