|In file manager or My Computer, select tools in the menu, then folder options, Click the view tab. Scroll down to hidden files and folders. Click on show. Click OK. Now we can see all hidden files. Windows is going to tell us where it's at.|
Upper right corner of the file manager is a search box. Type in normal.dot hit enter key. If you click on the C: first, then search, you search the entire drive. You can also click Users or Documents and settings or any other folder to limit the search time.
To restore the hidden files, do the process again, but select do not display at the last.
And it gets better! You can use wild cards to search with, to find any file.
