How can I search the windows registry with regular expressions?

Is there a tool or method with which I can search the windows registry with regular expressions?

Solution 1:

The free RegAlyzer utility searches by substring, wildcard (*,?), boolean (AND OR NOT), and regular expression:

RegAlyzer is a tool to browse and change the registry. It was created because of a few features we missed in the original regedit tool, from support for exotic value types over background and regular expression search to better bookmarks, displaying .reg files in the accustomed style and a history view.

Solution 2:

You can use PowerShell with -match:

dir HKCU:\ -rec -ea SilentlyContinue |   

ForEach-Object {   
       if((get-itemproperty -Path $_.PsPath) -match "\wSomestring\w")  
    {   
          $_.PsPath
    }   
} 

This will search the HKEY_CURRENT_USER hive.
