Reg Organizer is a feature-packed program that provides integrated services for Microsoft Windows XP – 10. The software speeds up and optimizes your operating system, freeing up additional system resources.

The utility allows you to remove unwanted programs from the system and search for traces of the uninstalled program. If there are “heavy” programs that run automatically on start-up in your Windows operating system, disabling them in an advanced startup manager can in some cases speed up the boot time and operation of your operating system. The disk cleanup feature frees up space on your system disk. And this is only part of features in the utility.

Features and Highlights
  • Using Reg Organizer to uninstall programs and remove its traces will help remove unwanted applications and their traces, thereby preventing littering up the registry and computer disks. This is very useful because not all programs delete their leftover and configuration files in the system registry after removal. This feature is powered by the Full Uninstall™ technology, developed by experts.
  • Advanced Startup Manager will help you control applications that automatically run with whenever your operating system is started. This would enable you to free up valuable resources for other purposes and in some cases speed up the boot time and operation of your Windows operating system.
  • With the automatic cleanup feature, you can delete a large amount of unnecessary information and free up space on the system disk. It can also enable you to remove unwanted updates, old Windows versions, and much more.
  • Ability to change many undocumented Windows settings (tweaks). In particular, it can accelerate the work of your system by sending the system a command to increase cache memory size or by unloading unused libraries, etc.
  • Advanced Registry Editor in Reg Organizer allows you to perform various operations with the system registry – you'll be able to export, import, copy key values, and do much more. The Registry Editor has many more features than the Registry Editor found in Windows.
  • Search & Replace in the registry allows you to find the keys related to the application in question and delete them if necessary. This is useful, for example, in the case where an application does not have an uninstall tool and after it has been "manually" deleted, unwanted files remain in the registry, which can affect other applications. At the same time, It makes a deeper search and often allows you to find even those keys associated with this application that can’t be found by other similar programs.
  • Defragmenting and compressing the registry: Increase the performance of the registry and consequently the overall performance of your system.
  • The registry file editor is designed to edit keys and parameters and to add and delete the content of.reg files. It is a very useful tool for transferring program settings from one computer to another. Unlike Windows Registry Editor (regedit), this registry file editor can create modular reg files containing various branches of registry keys.
  • Viewing registry files (*.reg) before importing their contents will enable you to examine the data before importing. When you view a reg file that you want to import, its contents are displayed as a tree in the app. This allows you to visualize all the keys that will be imported into the registry.
  • Tracking registry keys will help monitor the actions of any program and see all changes made to the registry in detail.
Note: 30 days trial version.

- Applications Tool: The Modify command is now available in the context menu for certain applications, allowing you to add or remove application components
- Automatic Reg Organizer update
- Improvement of certain visual elements, such as displaying cleanup part titles in two lines on the main screen within the Privacy section to prevent them from being truncated
- Undo Changes Center: It is possible to resize the internal parts of the window

Fixed:
- If the background cleanup is enabled, the Reg Organizer window could appear without information about the cleanup performed

- New feature: Scheduled (background) cleaning. If enabled, the program can run periodically in the background and report when it is possible to free some disk space
- The Maximum cleanup mode of the System Cleanup tool now finds more unnecessary files. This is made possible by automatically adjusting the cleanup locations settings to free up the maximum amount of space when this mode is activated. In the previous version, the same cleanup locations settings were used for both the normal and Maximum cleanup modes, with the only difference being the set of cleanup locations they targeted
- Added an option to increase the safety of System Cleanup: "Remove only files older than 24 hours from the temporary folder"

These options became available for some applications during uninstall:
- Speed Up the Standard Uninstaller by Hiding Unnecessary Windows.
- Standard Uninstaller Only. No Traces Lookup.
- Forced Uninstall: No Standard Uninstaller
- When uninstalling applications, an extra screen has been removed that suggested searching for their traces in the system. Now the search starts automatically when the standard uninstaller finishes, and you will shortly see the number of application traces found in the system.
