I twisted Gordon’s arm to get it, but here’s an exclusive coupons to get Registry Booster for only $19.95:

• Registry Booster - $20 off RegistryBooster 2010, only $19.95 + Free System Tweaker (Posted on 4/27/09 and Expires on 12/31/15)

Residual files, unused and undeleted drivers, and corrupt or bad entries in registry settings will quickly litter even the newest of computers. The result? Frequent error messages, slow start-ups, declining and poor performance and registry integrity, unstable and frequent application errors and crashes, and, at times, even an inability to start Windows.

If you’re looking for something that’s 100% effective in cleaning the Windows registry, you’re likely looking going to spend about $129. On what? Mac OS X.
