Tweak the mouse scroll wheel

If your finger is getting sore from all the scrolling around you do on web pages and documents, you can actually tweak the resolution of your mouse's scroll wheel in Windows Vista. By default the OS scrolls 3 lines at a time, but if you want faster scrolling and less finger abuse, this is easy to change with a small registry edit.

To increase mouse wheel scroll speed in Vista:

Open Regedit (open 'start' menu and type 'regedit.')

Navigate to 'HKEY_CURRENT_USER\Control Panel\Desktop'

Scroll down to the 'WheelScrollLines' value and double click it to edit.

Larger values equate to larger 'notches' on the scroll wheel, but this will require a restart before it's effective.
