NirSoft's RegScanner is an enhanced Registry scan and search tool. When it finds the specified values, you can open them in RegEdit for modifying. RegScanner can also save and export .reg files that RegEdit can open. This simple but effective tool is portable freeware.
RegScanner opens with its Registry Scan Options dialog displayed, and we had to enter at least one character in the Find String field to proceed. We could select a Matching method from a drop-down list as well as choose to have the program look at Values, Data, Keys, and Unicode strings. We could also choose base keys to scan, limit the display to certain values, exclude keys from the scan, and make other choices. We entered a short string and clicked OK, and RegScanner scanned our Registry, displaying its results in a small window that showed a lot of data in a series of customizable headings. We could save, copy, and export selected values or whole lists; view the properties of any entry; create reports; and more from the program's file menu and toolbar. Selecting any item and right-clicking it opened an extensive menu of choices, including Open In RegEdit, which we selected. The Windows Registry Editor opened almost immediately with the selected items displayed.
Although RegScanner is quite easy to use, inexperienced users should be careful before modifying any Registry values with RegEdit. RegScanner itself won't hurt your system, but tinkering around in the Registry certainly can, so we recommend the usual precautions before changing anything, including creating System Restore Points and full backups. RegScanner reveals a lot of information about your Registry and finds things fast when you need to make changes.
