What is Registry Cleaner
Registry cleaning with a safety layer before changing
Registry Cleaner looks for references that may remain after uninstalling software and helps to review orphan entries before removing them.
Before a cleanup, the application creates a .reg backup of the affected keys. When working in protected system areas, it requests administrator privileges through UAC.
Architecture: A single-file portable binary with a UAC requireAdministrator manifest for controlled access to protected Registry hives.
Important: Deleting necessary Registry entries can affect programs or Windows. Review the results and keep the .reg backup before confirming changes.

Guide and tips
What happens to the Windows Registry after you uninstall programs?
The Windows Registry stores information used by the operating system and many installed apps. When a program is uninstalled, its uninstaller may remove some of this information, but some entries can remain, depending on how the software was developed.
A leftover reference does not necessarily mean something is wrong with Windows. Some entries retain settings or information that a program may need if reinstalled, while others no longer serve a purpose after uninstallation.
Registry Cleaner helps identify references that appear to be orphaned. It analyzes the relevant entries and lets you review the results before making any changes.
The Registry is an important part of Windows, so any changes should be made carefully. The app creates a .reg backup before cleanup, giving you a copy of the affected keys that can be used if restoration is needed.
