Today I came across a very interesting registry key which I wanna share. If you go to your "Start" menu and open the "Run" dialog from there, you will see a dropdown list labeled as "Open". This list contains the last few entries you wrote there [probably last 26 entry is its limit]. This list populated from the following registry key
"HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\RunMRU"
Lets try yourself, and you know you can make some funny staff from there.
Have fun coding, take care.
