Fix Broken Registry Items in Windows 10

Wondering how you can fix broken registry items in Windows 10? Then consider yourself lucky because this guide covers all the methods and steps to help you fix corrupted or invalid registry entries. Read on for more details.

What’s Windows Registry?

Windows registry can be defined at the main database of the Operating system. It stores the parameters that control Windows startup, hardware, and software functions.

The registry consists of two basic elements:

  • Keys (primary keys, child keys)
  • Values

These elements are used by the operating system to launch programs, install new software, and change hardware, among a host of other functions.


What Causes Broken Registry Items?

There are many causes of broken registry items. Here are the 3 most common ones:

1. Registry fragmentation

This is often associated with duplicate keys. Registry fragments often result from software uninstallations or upgrades.

2. System shutdown errors

Unexpected PC shutdowns or crashes may interfere with the saving of registry copies, like is normally the case during normal shutdowns. That can lead to breaks in the registry.

3. Malware and viruses

Malware and viruses have a tendency to modify the system’s registry. This can compromise the operations of your PC.


A corrupted registry can severely impact the overall performance of your computer. Luckily, it’s possible to tweak registry entries. And there are many ways to help you do that. Here are some methods you can use to fix broken registry items in Windows 10.

Method 1: Restore Registry

This method entails reverting the system’s registry back to a previous restore point that had no broken items. It’s recommended to always enable the System Restore feature on your PC.
