Search Results to Text File in Windows Vista

1. Do a standard search in Windows Explorer.  
• In this case I want .mxd's modified after March 22, 2009 so in the search box enter “*.mxd date:>3/22/2009”
2. When search is done highlight all results (CTRL-A)
3. Hold down SHIFT, hover over results and right-click choosing “Copy as Path”
4. Paste results in Notepad
