As you all know that the registry is the most important component of your Windows PC. The Windows Registry is a hierarchical database which stores settings for everything on your Windows PC. It may be hardware, software, and user profiles configuration information.The registry controls and manages the working of all programs installed on your computer. You can say that Windows system cannot work without the help of the registry. Whenever you boot the system, all the registry is read into memory. It means the role of the registry starts from the boot-up of the machine.
7 reasons to clean the Windows Registry:
1. Application Uninstallation
Whenever an application is installed, many entries are added to the registry. Only then the application gets in working order. Therefore, when you uninstall that application, these entries must get deleted. This does not happen. This problem increases the size of the registry. Thus, it becomes unstable.
2. Old entries
Whatever task you perform on the system, that makes an entry in the registry. These entries must also get deleted on the completion of that task. However, this is not done and the registry size gets increases.
3. Program re-installation
Every time, an application is re-installed, some keys are added without deleting the keys that were added to the first-time installation of that application. This again increases the size of the registry.
4. Vacant spaces
Whenever an entry is deleted, it leaves a vacant space. These vacant spaces keep on building over time to time. This lead to registry fragmentation and makes it unstable. This causes the system slowdown and increases the data access time.
5. Malicious entries
When a virus, Trojans, spyware, malware, and adware attack your system. They insert invalid entries in the registry. These entries generate system errors. Thus, they damage the registry and causes the system to breakdown
6. Registry keys that are almost impossible to remove
When a software is purchased, its license agreement also comes in. This causes keys to be entered in the registry to save license information on your system. Many spyware and malware programs also add irremovable entries to the registry. Thus, the number of keys keep increasing to cause the registry to an unstable system.
7. System shutdown
As informed earlier, system boot moves the registry to system memory to ensure faster data access. However, this must be noted that any changes done in the registry during the operational time, are updated to the system registry during the shutdown process. These registry entries get corrupted if there is a power failure or system crash take place or improper shutdown is done.
How to Make the Registry Error-free
There are many more errors that may cause problems in the registry. So, the registry needs continuous cleaning. There are many methods for editing the registry, but you can use the Registry Editor to manually scan and delete invalid registry entries, which you can launch from the start menu search or run boxes. Once you have opened the editor, you will be presented with a tree view of keys on the left-hand side, and the values on the right. The most important thing you will want to do when editing the registry is to export the entire key before you make any changes. However, you should also remain careful of incorrect editing.
