Windows 7 / Windows 2008 R2 search simply doesn't work!

Windows search doesn't find files when searching for content related search e.g. search all files that have XXXX in them

Now i don't know how this passed any kind of test on the developers side / QA.

On the other hand, I can tell you that in MAC OS the search simply works

Any way as a solution you could use WinGrep to search for files
