When we delete a program in Windows 10 we usually do it from the Control Panel or from the contextual menu of the program in the Start menu, but what we rarely know is that when that program was installed on the system, in the system registries Links or keys have been created that allow Windows 10 to manage some application parameters , for example, if we edit the program's preferences, these changes are applied and updated in the registry..
For this reason, when an application is eliminated, it will not always be deleted 100% in its entirety, there are still records stored in the editor, and this sooner or later can have a negative impact on the performance of the computer since some of these records can take system resources.
TechnoWikis will explain to you how to delete a registry of an application or program that has been uninstalled in Windows 10..
