What’s silsvc.exe (Microsoft Server Infrastructure License Service)? Is it safe or a virus?

Silsvc.exe is a executable file used by Microsoft Windows to manage the Server Infrastructure License Service. This service is responsible for managing licenses for Microsoft server infrastructure products. Silsvc.exe helps ensure that the appropriate licenses are assigned and used correctly within the server infrastructure.

Microsoft server product licensing involves two main models: Per Core/CAL and Server/CAL. In the Per Core model, licenses are based on the number of physical cores in the server, which is common for products like SQL Server. In the Server/CAL model, used for Windows Server, organizations need a server license for each instance and a Client Access License (CAL) for each user or device accessing the server. Microsoft also offers subscription-based licensing through the Cloud Solution Provider program, which provides flexibility for organizations using cloud services like Azure by allowing them to scale licenses according to their needs.

What does it mean if someone is the publisher of a PC .exe (executable or process)?

The publisher of an executable is the entity responsible for its distribution and authenticity. Most processes/executables on your PC should be signed. The signature on the executable should have been verified through a third party whose job it is to make sure the entity is who it says it is. Find an unsigned executable? You should consider scanning any completely unsigned .exe on your PC.
