A common mistake that can be confusing

Those of you who have been using Windows for a while may have come across the “RPC Server is Unavailable” error. This is one of the most common errors that you can encounter when using the Windows operating system and often leaves more novice Windows users confused as to why it popped up in the first place.

However, you don't need to worry because it is not a serious or dangerous error, so all your programs and data are safe. RPC stands for Remote Procedure Call, a method that some applications use to communicate with other applications running on the same computer.

This means that RPC allows different processes to communicate with each other to perform a task.
