How to Fix Windows Registry Errors

This post would tech you how to fix Windows Registry Errors by yourself!

What is the Registry of a computer?

The registry is essentially a massive internal database containing important, machine specific information regarding almost everything in your machine:

  • System Hardware
  • Installed Software and Drivers
  • System Settings
  • Profile Information

Any long time Windows user knows that a single corrupt registry entry can kill an entire Windows installation! A thing that we can all agree on is the complexity of the Windows operating system, which handles massive amounts of operations. As with all complicated systems a central database system is required to make these operations gel together. The Windows registry is that central database system, utilised by the operating system to store all the most important settings information, for user profiles, software and hardware devices. No matter what you do on your computer, you can be sure some form of footprint will be left behind in your registry.

Make a change to your desktop background, and that change will be saved in the registry. Alter your internet browser homepage, and your registry is changed to reflect that. Install a new program onto your computer, and its settings will be stored in the registry, remove the program and the registry settings are removed right along with it.

The Windows registry was created using a tree-like structure, with its main branches comprised of hives, keys and values.

The hives are:

HKEY_CLASSES_ROOT – This hive holds information on all the registered programs in your computer, including OLE object classes and file associations.
HKEY_LOCAL_MACHINE – This hive holds most of your hardware settings data, along with third-party and OS application data.
HKEY_USERS – This one holds settings data for all the users of your computer.
HKEY_CURRENT_USER – This hive holds settings data exclusively for the current user profile that you’re logged in with.
HKEY_CURRENT_CONFIG – This one contains settings data for the printer and display. The information in this hive is not permanent, as the data contained within it is loaded each time the computer boots up.

The computer accesses the registry thousands of times per second, so one missing or corrupted registry entry is capable of causing a whole heap of problems for your computer.

Why Should You Clean The Registry?

As you should already know, everything that occurs on your computer corresponds with the registry with new entries and values being constantly written to. Unfortunately, like with all systems, the registry is not without its flaws and can, over time become inundated with outdated entries. In some situations, these files can even become corrupted, creating additional problems for your computer.

This especially reigns true for those individuals that like to uninstall and install programs a lot, since some applications do not remove the registry entries that they initially created once you remove them.

When you clean the registry, you delete these obsolete entries while repairing the corrupted ones, which ultimately improve the computer’s ability to access the registry.

The less time the operating system needs to access the correct registry entry, the faster it will execute operations. That is how cleaning the registry improves system performance.

Microsoft doesn’t feature a dedicated cleaner tool with their operating system. This means that you are forced to either fix it manually or use a third-party application.
