Suddenly I found lots of service's names double in Windows 10 services! They seem to use an extension number that changes every time the computer boots. Some them have their description in Portuguese (My pc language) and others in English.
What could have caused this?
MS did it on purpose, so people would not disable them, easily, because they are sort of essential. But once you disable the parent, via the registry, the child service, with a randomized number, will be disabled too.
I think what you are seeing is the service, and the server for the service, to allow other apps to interact with the service.
There is little documentation regarding this and most of what is available is very technical. I don't presume to understand it. But from what I have seen this is completely normal. I see the same thing in Windows 10 v1909.
There is much about Windows, as with any modern OS, for which there is limited documentation. This is particularly true for an evolving OS like Windows 10. Expect that updates will bring changes and documentation may not be immediately available. I expect further information will be provided but that may take many months. And you may not understand it when it does.
When you see something that seems unusual or strange it is best to keep an open mind about it. Do not immediately conclude that something is wrong. Very often you will be wrong.
