Windows Registry is most vital component of Windows Operating System which deals with all software and hardware configuration. It is responsible for all tasks and proper functioning of all applications and programs installed on the system.
The Registry hive consists of five root keys:
1. HKEY_CLASSES_ROOT
2. HKEY_CURRENT_USER
3. HKEY_LOCAL_MACHINE
4. HKEY_USERS
5. HKEY_CURRENT_CONFIG
Our system normally stores all information related to
1) File Associations
2) User Preferences
3) Current User Settings
4) Operating System Settings
5) Hardware Configuration Information
6) Software Configuration Information
If you click on any of the Root Keys then you would realize that each key is part of sub-tree that contains sub-keys and entries within them. When we perform install OR un-install activity on our system then sub-keys and entries are added or deleted from the registry. Many times when we uninstall any application from the system, it lefts behind vacant spaces or holes and some entries left behind in the registry.
These entries build up lot of debris inside registry that leads to it unwarranted growth. To prevent from fragmentation and corruption you may use registry-cleaner to repair and restore it to a health working condition.
