Computers can be a pain in the arse sometimes

I don’t know how she did it… but the wife was tinkering around in windows XP (home) and has changed a folder option that I can’t seem to undo. Normally when you double-click on a folder it should then open up and show you the contents of the folder. Now when I double-click, the folder opens up to show nothing but a search tool on the left side.

I have tried looking through all the folder options and even reset everything that had a reset button for it, but nothing works and this is anoying as hell.

Anyone got any ideas?
