Ever wanted to quickly find out what application is listed in the registry’s Uninstall key? Wanted to know what sub-key name it has and what version is recorded?

EnumInstalledApp is the CLi utility for you!

Really? What can it do?

EnumInstalledApp queries the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall registry key for a particular keyword or full name as passed on the command line. It’s scope, by default, is to find registry sub keys whose DisplayName value contains the passed keyword/s. It will list each match by sub key name, DisplayName and DisplayVersion:

Quite a bit! In a nutshell:

  • Search for multiple keyword/s or full names (with spaces!)
  • Perform a case sensitive search to narrow results
  • Alter the search scope:
    • Find matches that contain keyword/s
    • Find matches that are exact
    • Find matches that start with keyword/s
  • On a 64-bit machine, include the 32-bit registry within search or search 32-bit only
  • Query a remote host over the network

All of EnumInstalledApp’s CLi usage options and explanations can be accessed by either running EnumInstalledApp.exe from within a command prompt or by using the -? argument12.

What computer system is it designed for?

EnumInstalledApp has been built for Microsoft Windows. It has been designed for and tested against Windows XP (all versions), Windows 7 (all versions) and Windows 8.x.

The .NET framework version 4 is required to be able to run EnumInstalledApp. Windows 8.x already includes a newer version of the .NET framework, but if you are intending to run this tool on any other edition of Windows you will first need to install the .NET 4 framework which can be found here.
