To update ggRock from the currently recommended 1809 to 2004 or 20H2+ versions available now. We also see nothing that would prevent ggRock from updating to the versions past 20H2 (2020) when new Windows versions release.

This feature is supported with ggRock Image Creation Tool 0.80 and newer.

Please make sure to perform stability testing on the new machines by playing games and doing some updates before applying the new image center-wide.

Windows Versions Supported

Updating with keeping the data

In most cases you will be able to simply update your existing System Image, thus preserving all of the data currently written to it (installed launchers, games, etc). Here are the steps to update "in place":

Step 1. Connect an empty physical drive to the client machine

Step 2. Boot the Machine via ggRock (PXE)

Step 3. Write the current image to the connected drive using the ggRock IC Tool

Open the ggRock IC Tool, navigate to the Clone Disk tab and select the drive you've installed to be a destination for the current OS. The drive will be formatted.

Leave the checkbox Complete disk transfer unchecked.

Shrinking the System Image to speed up the Update

In case you want to speed up the cloning that ggRock IC Tool does - you can always first shrink your volume using Disk Management utility built into Windows.

Transferring the entire disk

In case there is an issue with cloning the disk you might want to select Complete disk transfer option. This will disable any optimization ggRock IC Tool might want to do and clone the entire disk raw, avoiding any issues that might occur there.

Step 4. Reboot the PC, setting BIOS to boot from the drive

Step 5. Disable update prevention measures and update Windows

Step 6. Reboot to apply the Windows update

Step 7. Disable Windows Defragmentation

Unfortunately Windows enabled Defragmentation after every feature update. To avoid extended writeback sizes we need to disable them after update.

Go to Defragment and Optimize Drives, Change settings, Choose and then deselect all drives, press Ok. Also deselect Automatic optimization for new devices.

Step 8. Generate VHD using the ggRock IC Tool

This step will require you to capture all NIC drivers again, restart the Machine and then create the VHD once all NICs (ignore the Wi-Fi ones if any) are in Configured Network Adapters:

Step 9. Import the VHD to ggRock as a new Image

Updating with a clean image

This feature is supported with ggRock Image Creation Tool 0.80 and newer as well.

In a rare case when updating in place would produce an unusable image you could always turn back to the clean image creation.
