Developer's description:

Registry Finder is a small fast utility that searches the Windows registry for specified strings. It was designed bearing in mind two requirements: search speed and simple, intuitive UI. All matches are displayed in a single list, so it is not necessary to press F3 each time to see the next match. The list displays key modification time and data size - the information not available in standard RegEdit. It does not require installation and can be launched from any removable media such as USB drive, for example. Registry Finder uses the Native API to search hidden keys (the keys with embedded null character) and values.
