Simply download the file and run the executable. There is no installer. There's no uninstaller. It's all self-contained.
Running the Program
You will be guided through the process with a "wizard" style series of questions. You will have the choice to pick and choose what you want to remove. It will not begin removing anything without prompting you first!
Click the images below to see a screen shot of various parts of the process.
From the welcome screen you can always check to make sure you're running the latest version of the PC Decrapifier.
Next, you can create a restore point. This can be useful to recover from an unexpected error. Using a restore point won't bring back any programs that were accidentally removed, but can be useful for driver problems.
Here's the list of items that the PC Decrapifier found on your computer that it knows something about. These are things that can be removed in an automated fashion that don't require you to click through a bunch of prompts.
Finally, here's a list of everything else on your PC. Did we miss anything? If so, select it here and the standard uninstaller will launch so that you can remove it. For these, you will see some prompts pop up asking you to confirm removal.
