Microsoft Registry Clean 4.1a

Developed a free utility from Microsoft that allows you to delete the Windows registry entries that contribute to unnecessary slow down the operating system and cause errors.
Pressing the button "Fix errors" contained in Registry Clean, lets you apply changes to the registry.

The only drawback is that this utility has been developed specifically for Windows 9x/NT but, unfortunately, was not then followed later by most of the programmers in Redmond and is therefore not recommended for use with newer versions of Windows.
