Question: Since there's no longer a taskbar/start menu Control Panel, how do you clear the history of the Run box in Windows 8?

Answer: 
You can use [CCleaner](http://www.piriform.com/ccleaner) to erase the run history.

Empty the registry key out:

```
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\TypedPaths]

```

This will kill the typed Run history.
