Windows Registry is a database which stores all the information regarding computer's configuration. It holds the information about system's software and hardware configuration, network settings, installing and uninstalling software and other configurations. In simple words, we can say that every action performed by your PC, such as installing and uninstalling software, working on applications and different configuration changes makes an entry or adds a key in the window registry. As you keep on working on your PC, registry size keeps on increasing which can result in decreased PC performance.
Now, let me ask you some questions?
- Does your PC runs slower day by day?
- Does your PC prompt unnecessary errors?
- Do you get different .DLL errors?
- Do system startup and shutdown and opening applications take a long time?
If your answer is "YES" to all or some of the questions then there can be errors within your window registry. Almost all the window registry errors are caused due to invalid or incorrect window registry entry. Even a single incorrect entry can cause trouble to your PC. When you work on your PC, many keys are added within the window registry, among those most of them are removed when you uninstall an application or your complete an activity. Some of the keys leave behind vacant spaces which results in the fragmentation of the window registry which in turn, results in general system slowdown and PC problems and errors.
Registry errors can be fixed and also prevented if you take proper care of your PC. To prevent registry errors you should:
Don't install games and software from suspicious websites.
Don't open suspicious e-mails.
Use program uninstaller to uninstall applications.
Regularly run virus scans and uninstall applications that are no longer used.
Despite various preventive methods, PC registry errors can occur.
