Microsoft PowerToy installs a new tool in your Control Panel. At startup you walk through a helpful wizard that displays different ClearType settings to help fill in and smooth out screen text. CRT display owners can try these tools, but generally we have found they work best for LCDs. Once you pick the best combination of letter density and smoothness for your eyes, the program sets it permanently. You can apply the setting as the default for all users on your system.
After Installing ClearType you will find a tool added to control panel to configure or reconfigure ClearType to select best vision.
In all, we love the change this simple tool has made on the usability of our laptop. It is one of those sweet little Microsoft giveaways that remains undiscovered by most users.
