PC REGISTRY GLOSSARY
Crash
This is when something goes wrong with the computer and it just stands still and stops working. Normally, things will get running again after re-starting the computer. This frustrating problem is frequently caused by registry problems.
DLL
Stands for Dynamic Link Library, it's a file that holds information needed by a program to be able to work. The registry stores information about DLL files often long after the programs have been removed. Registry cleaners remove those no-longer-needed entries from the registry.
Defrag, Defragment
This is the process of re-organizing information on your hard drive. Over time, as things are installed to or removed from the registry, it can become disordered. Defragmenting it will put it back orderly and improve its performance. You need to run defrag at least once a month.
Invalid Entry
An invalid entry is some information that is no longer needed but is still stored in the Windows registry. Like when you uninstall a program, the entries to do with the program should also be removed. But often, this isn’t the case because Windows doesn’t clean its registry well.
Registry Key
This is part of the registry in Microsoft Windows that holds information related to the settings for something on your computer. Registry keys are created when you install software, hardware or change a setting on your computer.
