How to disable Windows update

In order to save performance, disk space, and network traffic, it makes sense to disable Windows update on low-power servers. However, we strongly advise you not to do this, as the server remains less secure without OS updates.

If you decide to disable Windows update, make sure that all the server roles and components you need for working (such as RDS or .NETFramework) are installed, because installation of some roles and features becomes impossible after the update disabling.

There are two ways to disable Windows Server 2012 updates:

  1. Disable automatic system updates receipt from the Internet
  2. Completely system update service disabling – completely disabling the Update API, which makes it impossible to install even local updates and components (for example .NETFramework)

Disable Windows update from the Internet

Receiving updates from the Internet is governed by the “Automatic Update Settings” policy. To change the parameter of this policy, go to the “Local Group Policy Editor” toolbar (also called as “gpedit.msc”).

1. Click ‘Start’ and type “gpedit.msc” in the search field. In the search results, click on the found app.
