The main window of Regalyzer resembles that of Regedit but you will notice the bar at the top that contains the search and a history function that displays the Registry keys that have been used lately. It also offers a way of pasting a Registry key into it to jump directly to that key, very handy if you quickly want to change a setting and have the full key at hand.

The search is independent from the main program and opens up in a new window. It displays the result just like Regscanner does which means that all search results are displayed immediately and you are not forced to jump from result to result like in Regedit. Four Search Styles are available: Simple Search, Wildcard Search, Boolean Search and Regular Expressions.

You can also limit the search to specific range, certain data types and several other options. There is also a find and replace feature build in. Once you have selected a key you will notice the additional tabs that contain Security Information, Additional Information and a Change Log besides the default display of the values of that key.

Regscanner is the usual high quality Nirsoft application. You can run it from any location without installation it and it works right out of the box. The Regscanner search form might look a bit intimidating but it is actually providing some much needed functions. It offers all the search functionality of Regedit plus the following advanced options:

• Case Sensitive Search
• Searching for Unicode String in Binary Value
• Exact Matches plus five additional criterias for matching strings.
• Display keys that have been modified in a time range
• Display data of a certain size (in bytes)
• Display only values of a certain type (like DWORD)
• Scan one, several or all Registry base keys

A double-click on an entry opens the selected key in Regedit. Results can be exported as .reg files which can be imported into Regedit.
