Install Windows Server Update Service (WSUS)


A WSUS server provides features that you can use to manage and distribute updates through a management console. A WSUS server can also be the update source for other WSUS servers within the organization. The WSUS server that acts as an update source is called an upstream server. In a WSUS implementation, at least one WSUS server on your network must be able to connect to Microsoft Update to get available update information.

WSUS Prerequisites

Before you enable the WSUS server role, confirm that the server meets the system requirements and confirm that you have the necessary permissions to complete the installation.

The minimum hardware requirements for WSUS are:

  • Processor: 1.4 gigahertz (GHz) x64 processor (2 Ghz or faster is recommended)
  • Memory: WSUS requires an additional 2 GB of RAM more than what is required by the server and all other services or software.
  • Available disk space: 10 GB (40 GB or greater is recommended)
  • Network adapter: 100 megabits per second (Mbps) or greater

Software Requirements:

  • For viewing reports, WSUS requires the Microsoft Report Viewer Redistributable 2008. On Windows Server 2016, WSUS requires Microsoft Report Viewer Runtime 2012
  • If you install roles or software updates that require you to restart the server when installation is complete, restart the server before you enable the WSUS server role.
  • Microsoft .NET Framework 4.0 must be installed on the server where the WSUS server role will be installed.
  • The NT Authority\Network Service account must have Full Control permissions for the following folders so that WSUS Administration snap-in displays correctly:
    • %windir%\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files
    • %windir%\Temp
  • Confirm that the account you plan to use to install WSUS is a member of the Local Administrators group.
