You’ve probably heard of the Windows Registry. It’s a database of files that exists at the center of your operating system. The registry controls how your operating system and its programs work. It tells your computer how to run and it keeps track of all of the changes made to your computer over time.
But when something goes wrong in the registry, it can be bad news for the rest of your computer. Registry problems are often very serious and they can open up massive holes in your system’s security. If you want to safeguard your system and ensure that it is running as fast as possible, then you’ll need to learn how to fix the Windows Registry. Here are the 2 best ways to do that:

Fixing the registry manually

There are two different ways to fix the Windows Registry. This is the hard way. Fixing the registry manually should only be done by those with technical experience. If something goes wrong while fixing the registry, it can cause your computer to completely break down.
Still want to proceed? All right, here’s how to fix registry problems on your own:
Step 1) Enter the registry by opening a run command and typing in regedit. Or, if you’re using Windows 7, just type regedit into the Start menu search bar and press ‘Enter’.
Step 2) The Registry Editor screen will pop up. Along the left-hand side of this screen, you’ll see folders for HKEY_CLASSES_ROOT, HKEY_CURRENT_USER, HKEY_LOCAL_MACHINE and a couple others. In most cases, the registry files you need to edit will be found under HKEY_CURRENT_USER or HKEY_LOCAL_MACHINE
Step 3) At this point, you should know which file you need to change. Each folder contains a number of different registry entries, and you might have to dig deep to find the entries you need. Once you encounter a registry entry, you can edit it or delete it.
Step 4) You should only be deleting registry entries if you have already tried to uninstall a program, but the uninstallation process failed. Sometimes, even successful uninstallation processes will leave behind files in the registry. Deleting these files can reduce problems on your PC and free up space on your hard drive. This will also completely remove a program from your system, which can pave the way for a successful reinstall or simply remove a troublesome virus.

Step 5) If the program is still installed on your computer, then you shouldn’t delete registry entries unless you absolutely have to. The program might require these entries in order to work, and deleting a certain entry could have serious effects across the rest of your computer. Instead, you’ll want to edit these registry entries. You can change the value of certain registry entries to alter the way programs work on your operating system.
Step 6) Whether you’re editing or deleting registry entries, your actions have the potential to cause serious harm to your computer. Unless you have specific directions from tech support or you’re editing the registry as a last-chance approach before reformatting, then manually changing registry files is generally a bad idea.
