This central database is where Windows keeps a list of the DLL file locations for your computer, and is where your system looks each time it wants to use a dll file such as userenv.dll. Unfortunately, it’s prone to becoming damaged and corrupted and is constantly being unable to read the files and references that it needs to open the files that it wants. This is a major problem that causes a lot of damage to many different parts of your system. Running a registry scan will remove all the damaged references inside the registry, allowing it to run as quickly and smoothly as possible.
