What is UNCserver.exe & How to Stop Running it in the Background?

Do you know what is UNCserver.exe? Do you know why your computer needs it and how to stop it from running in the background and even in Safe Mode ?

UNCserver.exe or Universal Naming Convention (\) is a network file and folder sharing protocol that allows client computers to access shared folders on the host computer. It is not the same as Server (SMB) which allows clients to access shared files and printers on a server in your network.

UNCserver.exe in Windows 10/8/7

The UNCserver process is an essential part of MS Windows networking in all later versions including 8, 7, Vista & XP. In fact, without UNCserver.exe, you will not be able to access any network shared folders and files over the network on your Windows computer!

It is also important for the sharing of printers on your computer. A Windows computer is unable to function as a print server without UNCserver.

However, computers running MS Windows are often reported to have this process running in background consuming memory and thus slowing down the system unnecessarily.

  2. Select More details to see all running processes in Windows 10/8/7.
  3. Scroll down to the bottom to see the list of Background processes (processes not associated with any window).
  4. Select UNCserver process by clicking on it.
  5. Now, click End task button to stop this process from running in the background and thus speed up your computer.

  1. Open Run dialog box by pressing [Windows key]+ [R], and type regedit to open the registry editor and navigate to the following key:
HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Services
  1. Right click on the key Services , select New and then select Key to create a new sub-key. Name the new key Universal Naming Convention (RPC) .
  2. Click on Universal Naming Convention (RPC) key, on the right pane, look for a DWORD value named Handle . If you do not find it, right click on the blank area and select New > DWORD (32-bit) Value and name it as Handle .
  3. Now, double click on the Handle and set its value to 0.
  4. Close registry editor and restart your computer to stop UNCserver process from running in the background.
