What is UNCServer.exe? Is it Safe or A Virus?

Last Updated on October 20, 2020 by Editor Futurescope

So, What is UNCServer.exe? UNCServer.exe is a system update server module runs as a separate windows task while System Update is running. The acronym UNC comes from Universal Naming Convention. The UNCServers.exe task starts as soon as Lenovo System Update is started and usually close along with it.  The task is also tied to the newer TVSU (Think Vantage System Update). It operates by opening the inbound TCP and UDP traffic to allow SU (System Update) to self-update and download any pending installation packages.

If one sees the UNCServer.exe task inside TaskManager.exe, it means that the module is actively working. However, as soon as the task is complete, the uncserver.exe task should automatically terminate. If one finds that the UNCServer.exe is always on, the chances are that his or her system is suffering from a bug that manifests by the refusal of the process to terminate after SU is closed.
