Reverse Buttons Lefties get no respect.
They're second-class citizens in a right-handed world, and there's no exception when it comes to computers. It might not make a big difference to most people, but the standard configuration of buttons on a mouse can be frustrating for some lefties. To compensate for differences in dexterity, left-handed users might prefer to reverse their mouse buttons.

Here's how to do it:
1. Open your registry and find this key: HKEY_CURRENT_USERControl PanelMouse.
If you can't find it, create it.
2. Create or modify the string value 'SwapMouseButtons', and set it to 1 to reverse your buttons.

Ban the Beep
The internal PC speaker is capable of creating some of the most annoying sounds known to man. If you get as agitated as I do by this high-pitched cacophony, there's a simple way to make it stop.

Disable the beeping with this simple tweak:
1. Open your registry and find this key: HKEY_CURRENT_USERControl PanelSound
2. Create or modify the string value named "Beep", and set it to "No" to disable the infernal beeping.
