RegistrySmart is a new software that allows users to quickly scan their computers to detect any problems, and automatically fix them so that you can keep on working without worrying about your computer reliability, or having to pay someone to come and fix it for you. RegistrySmart performs some these basic tasks: fix Windows-Installer Errors, repair DLL files, solve Windows startup errors, IE and Runtime errors, it prevents your PC from freezing or crashing, plus some other exciting features as well.
The software runs on Windows Vista and previous versions as well, but there’s no information on pricing. By visiting the site, you can get a complimentary diagnosis scan to check out what might be wrong with your PC, which launches as a downloadable .exe, and probably after that you’ll get the pricing information. I reckon this approach should be reconsidered, as some people might be weary of downloading an .exe app knowing that they might get charged for an unknown sum later on.
