By default, Start Menu items are cascaded as columns across the screen. This can get annoying and inconvenient when your Start Menu list becomes large. This hack will enable you to switch the default Start Menu display mode to a scrolling menu.
Navigate to:
HCU\ Software\ Microsoft\ Windows\ CurrentVersion\ Explorer\ Advanced
And to:
HLM\ Software\ Microsoft\ Windows\ CurrentVersion\ Explorer\ Advanced
To enable Start Menu scrolling, change the value of StartMenuScrollPrograms to “Yes”. Set the value to “No” for the default multiple-column display. Reboot or log out and back in for the change to take effect.
