What is UNCServer.exe?

[CustomerX]

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?

Hello mate,

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.

Good call. I rebooted and it wasn't there. I open and closed ThankVantage System Update, but UNCServer.exe remains running in the background.

Even worse: if you are using windows firewall, when you start lenovo system update, two inbound rules are programmatically inserted in the firewall that permit inbound TCP and UDP traffic to UNCServer.exe. I have found no way to avoid this. Every time I run system update, I have to delete the two new rules by hand. Even if I create blocking rules to block inbound traffic to UNCServer.exe, system update will eliminate my rules (any rules regarding this exe) and create its own ones. Awesome!

Blargh. I was wondering what that is. Alt+Tabbing to it and hitting Alt+F4 makes it go away though.

Really annoying to have it take up a slot in the task list when ALT+Tabbing
