Hi **jacob rasel**

In Windows File Protection, the operating system prevents system DLLs from being updated or deleted by an unauthorized agent. Therefore, when a program installation tries to remove or update a DLL that is defined as a system DLL, Windows File Protection will look for a valid digital signature.
