However if you are running Windows XP you may be
out of luck because for some reason Microsoft decided that by default it will
only search in certain file types in order to improve performance.
There is a quick solution to this problem though.
All you have to do is run regedit.exe and navigate the tree to
HKEY_LOCAL_MACHINE ..SYSTEM ....CurrentControlSet ......Control ........ContentIndex
inside that key modify or create a key called FilterFilesWithUnknownExtensions
and set the dword to 00000001. Close regedit and reboot your machine then you
can use search to find a word or phrase in all files.
