= Update VirtIO drivers and the guest agent on a Windows VM

[role="_abstract"]
You can update the VirtIO drivers and the QEMU guest agent on a Windows virtual machine (VM) by using the `virtio-win` guest tools installer. This method updates both the drivers and the guest agent in one step.

.Prerequisites

* The `container-native-virtualization/virtio-win` container disk must be attached to the VM as a SATA CD drive. You can mount the disk from the web console by selecting the *Mount Windows drivers disk* checkbox on the *Configuration* -> *Storage* tab.

.Procedure

. Start the VM and connect to a graphical console.
. Log in to the Windows guest operating system.
. Open *File Explorer* and navigate to the `virtio-win` CD drive.
. Double-click the `virtio-win-gt-x64` installer to launch the guest tools setup wizard.
. Follow the prompts in the setup wizard. The default options update the VirtIO drivers and the QEMU guest agent.
. After the update is complete, click *Finish*.
. Reboot the VM.

.Verification

. On the Windows VM, navigate to *Device Manager*.
. Select a device.
. Select the *Driver* tab.
. Click *Driver Details* and confirm that the `virtio` driver details displays the correct version.
