How to Delete Registry Entries Manually


The Windows registry is a database repository of information about a computer's configuration. When you install, uninstall, or simply use software programs, registry entries are created, modified, or deleted. To completely uninstall software, its related registry entries must be deleted. This step-by-step article describes how to delete registry keys and values manually.

Warning: Manually deleting registry entries is difficult and risky. If you delete the wrong registry keys or values, your computer may crash and important data may be lost. Before you start, always be sure to back up your PC important files and set a System Restore point (click Start > All Programs > Accessories > System Tools > System Restore, and follow the on-screen instructions) or run Final Uninstaller, a trusted uninstaller software, to automatically delete unwanted registry entries and clean registry.
