I am running Windows 7 on a ThinkPad T410. I have all the latest updates installed from both Microsoft and Lenovo.
When I use Alt+Tab, I see the following application.
It is located here: C:\Program Files\Lenovo\System Update\UNCServer.exe
Can anyone tell me what this does and why it is always running on my computer?

The latest version of TVSU let that thing open all the time. Don't know what it is. I have to close that manually each time I check for updates with TVSU.

I can attest to that. Saw it for first time today, as akKI2904 said -- about 6 1/2 years later. I was on mission to get Microphone Mute Button in ThinkPad W530 to work again after reformatting. My drive is too tiny for hulk programs of today that refuse to side-load to external drive. Back to point: I think perhaps it shows for allowing / participating in anonymous usage collection of their utility tools. Not sure though. Sometimes I say yes to participate, sometimes I say no. I might hunt down the participation and tick (confirm selection) NO to see if it stops. I've yet to reboot, but based on other's findings, I should expect to see this again.
Still a useful post, CustomerX.

UNCserver.exe is system update(Universal Naming Convention) server module.
It runs as a separate windows task while System Update is running. It opens inbound TCP and UDP traffic to allow SU to self update and download install packages.
If you ALT+tab during SU running, a task window will appear with uncserver.exe.
On my windows 10 system, upon exit of SU, the uncserver.exe task is no longer showing via ALT+tab.
If you still see this task after SU is closed, please state the OS you are running and which version of SU you are using. Years ago there was a bug in SU where uncserver.exe did not terminate after SU was closed and left a ICON on the task bar, as/was showing in message 1 of this post.
