Windows 8 File Explorer Search

Hiya!

I have about 5 hard drives in my system. I open File Explorer in Windows 8 and click on "Computer". All the drives show up.

I click in the box that says "Search Computer". I enter in any search term. Let's say "*.iso" to find all iso files on all my drives.

I hit enter. NOTHING happens. :confused:

In Windows 7 this used to execute a search across all my drives.

If I double click on each drive individually and put "*.iso" in the search box then it works fine.

How do I search across all my drives from the File Explorer Computer location????

Thanks!
