Create a VM. **Create** (if not already created) and **Turn On** a ggRock VM with desired System Image and Games Image you with to apply updates to in l**ocal drives mode** (*This is for speed purposes - you could boot the VM in network mode, but it serves only to slow the process down here*). (See the **Virtual Machines Administration Manual**for more information). Additionally, please refer to "[**Controlling a Virtual Machine**](https://app.crisp.chat/website/574ccbdb-fedc-4721-8ca2-1639892b6db8/helpdesk/articles/en/37940d52-7c9e-4ec5-9a50-14f22a3efe9e/)" for more information on how to control VMs. **NOTE:** ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-56-1368-PM.png?version=1&modificationDate=1743378581169&cacheVersion=1&api=v2) *If you do not yet have a VM set up on your ggRock server, please follow the steps in "[**Creating a Virtual Machine**](https://app.crisp.chat/website/574ccbdb-fedc-4721-8ca2-1639892b6db8/helpdesk/articles/en/37940d52-7c9e-4ec5-9a50-14f22a3efe9e/)******" to do so.* ### 2. Enable "Keep Writebacks" in the Settings of the VM. (See the Machines for more information). **NOTE:** *This is a precautionary measure in the event that an update you are installing requires a reboot - without "Keep Writebacks" enabled the changes will be lost on reboot.* ### 3. Turn on the VM. ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-58-1516-PM.png?version=1&modificationDate=1743378581211&cacheVersion=1&api=v2) ### 4. Control the VM. ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-56-3578-PM.png?version=1&modificationDate=1743378581228&cacheVersion=1&api=v2) ### 5. Install the game, application, or other updates required by your center. ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-57-6794-PM.png?version=1&modificationDate=1743378581234&cacheVersion=1&api=v2) Open the game launcher, game, or application you wish to apply updates to. Install the updates as you would on any standard computer. ### 6. Shut Down the Virtual Machine. ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-57-0142-PM.png?version=1&modificationDate=1743378581256&cacheVersion=1&api=v2) ### 7. Disable "Keep Writebacks" in the Settings of the VM. ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-56-5684-PM.png?version=1&modificationDate=1743378581278&cacheVersion=1&api=v2) (See the **Machines Administration Manual**for more information). ### 8. Apply Writebacks. ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-58-6857-PM.png?version=1&modificationDate=1743378581287&cacheVersion=1&api=v2) (See **Applying Writebacks** for more information). Enter a comment when prompted (typically initials of the administrator, the date, and the contents (e.g. games, applications updated). ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-56-7752-PM.png?version=1&modificationDate=1743378581296&cacheVersion=1&api=v2) **Example:** *ABC - 01-12-2021 - Updated Fortnite, COD:MW (launched to install shaders), and Google Chrome.* ### 9. Confirm Update Installation ![](https://ggcircuit.atlassian.net/wiki/download/attachments/15860961/undefined-Mar-30-2025-11-48-58-4733-PM.png?version=1&modificationDate=1743378581307&cacheVersion=1&api=v2) Boot a system that uses the System Image and Game Image pair you updated with the VM, then confirm that the game or application update has been applied successfully. ### 10. Reboot All Machines In order for the changes to take effect, all machines currently powered on must be rebooted so that the newly-created snapshot becomes active. ### **Additional Information** * Certain game or application updates may require a reboot. Ensure "Keep Writebacks" is enabled prior to rebooting so that your changes are not discarded. * If changes have been made and committed from a separate Machine while you were working on this one, it will not be possible to apply writebacks. Please coordinate with other administrators at your center when updating games and applications. * See "**How Writebacks and Snapshots Work**" for more information.
