Windows updating service
When the tier is updated, VMM updates the virtual machines in the tier according to the upgrade domain to which they belong.
VMM upgrades one upgrade domain at a time, shutting down the virtual machines running within the upgrade domain, updating them, bringing them back online, and then moving on to the next upgrade domain.
We do not recommend using a computer without the latest updates, because they're often key to keeping your Windows 10 PC running properly.
However, there will be times when you may want to manually apply new updates, when you want to install them during a particular time, or because you want to wait until you're sure the update will not cause issues.
In Deep Freeze 8.35 and higher a change in behaviours was introduced to better allow for the control of the Windows Update process on protected machines.
If you're running Windows 10 Pro or higher, it's possible to retake control and prevent the OS from downloading and installing updates automatically using the Local Group Policy Editor or the Registry.Most configuration changes to virtual machines and application updates can be applied in this manner.To minimize service interruptions when a tier is updated in-place, you can specify more than one upgrade domain in the tier properties.Upgrade domains have no connection to Active Directory domains.You can specify the number of upgrade domains you want to use, and then VMM arbitrarily assigns the virtual machines to an upgrade domain.
