Overview

This document provides guidance on updating Windows patches on a Windows Server 2012 operating system.

Directions

Updating via Public Network

You can install patches using the system's Windows Update service. Follow the steps below:

  1. Log in to the Windows CVM.
  2. Click Start > Control Panel > Windows Update to open the Windows Update window.
  3. Click Check for Updates and wait for the process to complete.
  4. After the check is completed, click [n important updates available] or [n optional updates available] in Windows Update.
  5. In the pop-up [Select Updates to Install] window, select the update programs to be installed and click Install.
    After the update is installed, if the system prompts that the system needs to be restarted, please restart the CVM in time.
Note:

When restarting the CVM after completing the patch update, you need to log in and monitor the CVM via VNC. If the system displays prompts such as "Updating, do not turn off the power" or "Configuration not complete", do not perform a hard shutdown. A hard shutdown may damage your CVM.

Updating via Private Network

If your CVM cannot connect to the public network, you can use the Converge Cloud private network patch server to install updates. The Converge Cloud Windows patch server includes most common updates for Windows but does not include hardware driver packages or some less frequently used server updates. Some less common services might not have updates available on the Converge Cloud private network patch server.
How to use the Converge Cloud private network patch server is as follows:

  1. Log in to the Windows CVM.
  2. Use IE browser to access and download the Converge Cloud private network setting tool (wusin.bat).
  3. wusin.bat: Contact engineers to obtain it.
  4. Use the administrator Cloud Platform Command Line Interface (CMD) to open wusin.bat. As shown below:
Note:

If you run the 'wusin.bat' tool directly via IE, the console window will automatically close, and you won't be able to observe the output information.

If you no longer need to use the Converge Cloud private network Windows patch server, you can download the cleanup tool wusout.bat to clean up. The method is as follows:

  1. Log in to the Windows CVM.
  2. Use IE browser to access and download the Converge Cloud intranet cleanup tool (wusout.bat). Contact engineers to obtain wusout.bat.
  3. Use the Administrator Cloud Platform Command Line Interface (CMD) to open wusout.bat. As shown below:
Note:

If you execute the wusout.bat tool directly through IE, the console window will be automatically closed and the output information cannot be observed.
