How Do I Repair the Registry - About Windows Registry
Windows registry is a database type file created while installing Windows. It contains all the information required by Windows to operate properly. For each application installed later, there is one or more corresponding entry in the Windows registry. In short, the Windows registry is a huge database which is consulted by Windows for each task.
If the registry contains broken entries, the computer may become unstable. If any record (called a key or subkey) is missing or contains incorrect information, it may take longer for Windows to load an application. The same happens when there are duplicate entries in the registry.
I would say the best method to repair the registry is parsing the registry manually and checking for duplicate, broken, and incorrect keys. However, this requires much time and knowledge about the registry entries and their formats. Since this is not possible for everyone, programmers developed several registry related software called registry cleaners or registry optimizers. These registry cleaners quickly scan the registry for invalid or broken keys and help you repair the registry.
The following section talks about using registry cleaners to repair the registry and precautions to take while using them.

How Do I Repair the Registry - Using Registry Cleaners and Precautions
Registry cleaners are the best answer to your question - how do I repair the registry. There are plenty of registry cleaners on the market. Check out our article, Freeware Registry Cleaner Roundup, for reviews of some of the best free Windows registry optimizers and cleaners.
Some registry cleaners offer aggressive modes to repair the registry. I won't suggest running registry cleaners in aggressive mode as they may remove important keys leading you to a BSOD (Blue Screen of Death). It is better to use the registry cleaners more frequently in normal mode than to use them once in aggressive mode.
If you feel that your registry has more errors, you can double check using another registry cleaner. For example, you can run the CCleaner and then run Comodo System Cleaner in normal mode to make sure there are no invalid/broken registry keys. Also, before attempting a repair of registry, it is always good to create a system restore point.
Note: If you can create a system image before cleaning the registry, it is much more helpful in case the registry cleaner deletes important keys by mistake and makes your system unbootable.
If your problem is not solved even after attempting a repair of registry, chances are that your profile is corrupt. You may create a new user profile and see if your problem is fixed. If not, you may need to reinstall the operating system to create a fresh registry.
