Create update rings that specify how and when Windows as a Service updates your Windows 10/11 devices with feature and quality updates. With Windows 10/11, new feature and quality updates include the contents of all previous updates. As long as you've installed the latest update, you know your Windows devices are up to date. Unlike with previous versions of Windows, you now must install the entire update instead of part of an update.
Update rings can also be used to upgrade your eligible Windows 10 devices to Windows 11. To do so, when creating a policy you use the setting named Upgrade Windows 10 devices to Latest Windows 11 release by configuring it as Yes. When you use update rings to upgrade to Windows 11, devices install the most current version of Windows 11. If you later set the upgrade setting back to No, devices that haven't started the upgrade won't start while devices that are in the process of upgrading will continue to do so. Devices that have completed the upgrade will remain with Windows 11. For more information on eligibility, see Windows 11 Specs and System Requirements Microsoft.
Intune Update rings for Windows 10 and later require the use of Windows Update for Business (WUfB), which supports devices that are Workplace Joined (WPJ). However, the following Intune Windows Update policy types use WUfB and Windows Update for Business deployment service (WUfB ds), which provides for additional capabilities that are not supported for WPJ devices.
Under Update ring settings, configure settings for your business needs. For information about the available settings, see Windows update settings. After configuring Update and User experience settings, select Next.
Under Scope tags, select + Select scope tags to open the Select tags pane if you want to apply them to the update ring. Choose one or more tags, and then click Select to add them to the update ring and return to the Scope tags page.
When configuring or editing Intune policies, some policy types might not display the Scope Tags configuration page if there are no custom defined scope tags for the tenant.If you don't see the Scope Tag option, ensure that at least one tag in addition to the default scope tag has been defined.
Under Assignments, choose + Select groups to include and then assign the update ring to one or more groups. Use + Select groups to exclude to fine-tune the assignment. Select Next to continue.
Under Review + create, review the settings, and then select Create when ready to save your Windows update ring. Your new update ring is displayed in the list of update rings.
In the portal, navigate to Devices > Windows > Update rings for Windows 10 and later and select the ring policy that you want to manage. Intune displays details similar to the following for the selected policy:
Select Delete to stop enforcing the settings of the selected Windows update ring. Deleting a ring removes its configuration from Intune so that Intune no longer applies and enforces those settings.
Deleting a ring from Intune doesn't modify the settings on devices that were assigned the update ring. Instead, the device keeps its current settings. Devices don't maintain a historical record of what settings they held previously. Devices can also receive settings from other update rings that remain active.
Select Pause to prevent assigned devices from receiving feature or quality updates for up to 35 days from the time you pause the ring. After the maximum days have passed, pause functionality automatically expires and the device scans Windows Updates for applicable updates. Following this scan, you can pause the updates again.If you resume a paused update ring, and then pause that ring again, the pause period resets to 35 days.
While an update ring is paused, you can select Resume to restore feature and quality updates for that ring to active operation. After you resume an update ring, you can pause that ring again.
An Intune administrator can use Uninstall to uninstall (roll back) the latest feature update or the latest quality update for an active or paused update ring. After uninstalling one type, you can then uninstall the other type. Intune doesn't support or manage the ability of users to uninstall updates.
For example, consider an update ring with a feature update uninstall period of 20 days. After 25 days you decide to roll back the latest feature update and use the Uninstall option. Devices that installed the feature update over 20 days ago can't uninstall it as they've removed the necessary bits as part of their maintenance. However, devices that only installed the feature update up to 19 days ago can uninstall the update if they successfully check in to receive the uninstall command before exceeding the 20-day uninstall period.
There are multiple options to get in-depth reporting for Windows 10/11 updates with Intune. To learn more about the reports for update rings, including details for the default view and the additional report tiles, see Windows update reports.
If call forwarding is available, you can forward calls to another number or Skype for Business contact, or ring another number at the same time as your mobile number. Call forwarding lets you send calls your current location if you're traveling or working from home, or route calls automatically to a coworker if you're out of the office.
Computer operating systems provide different levels of access to resources. A protection ring is one of two or more hierarchical levels or layers of privilege within the architecture of a computer system. This is generally hardware-enforced by some CPU architectures that provide different CPU modes at the hardware or microcode level. Rings are arranged in a hierarchy from most privileged (most trusted, usually numbered zero) to least privileged (least trusted, usually with the highest ring number). On most operating systems, Ring 0 is the level with the most privileges and interacts most directly with the physical hardware such as certain CPU functionality (e.g. the control registers) and I/O controllers. With the increasing prevalence of virtualization, many CPUs have added another level (conceptually ring -1) for the hypervisor.
Special mechanisms are provided to allow an outer ring to access an inner ring's resources in a predefined manner, as opposed to allowing arbitrary usage. Correctly gating access between rings can improve security by preventing programs from one ring or privilege level from misusing resources intended for programs in another. For example, spyware running as a user program in Ring 3 should be prevented from turning on a web camera without informing the user, since hardware access should be a Ring 1 function reserved for device drivers. Programs such as web browsers running in higher numbered rings must request access to the network, a resource restricted to a lower numbered ring.
Multiple rings of protection were among the most revolutionary concepts introduced by the Multics operating system, a highly secure predecessor of today's Unix family of operating systems. The GE 645 mainframe computer did have some hardware access control, including the same two modes that the other GE-600 series machines had, and segment-level permissions in its memory management unit ("Appending Unit"), but that was not sufficient to provide full support for rings in hardware, so Multics supported them by trapping ring transitions in software;[3] its successor, the Honeywell 6180, implemented them in hardware, with support for eight rings;[4] Protection rings in Multics were separate from CPU modes; code in all rings other than ring 0, and some ring 0 code, ran in slave mode.[5]
However, most general-purpose systems use only two rings, even if the hardware they run on provides more CPU modes than that. For example, Windows 7 and Windows Server 2008 (and their predecessors) use only two rings, with ring 0 corresponding to kernel mode and ring 3 to user mode,[6] because earlier versions of Windows NT ran on processors that supported only two protection levels.[7]
Many modern CPU architectures (including the popular Intel x86 architecture) include some form of ring protection, although the Windows NT operating system, like Unix, does not fully utilize this feature. OS/2 does to some extent, using three rings:[8] ring 0 for kernel code and device drivers, ring 2 for privileged code (user programs with I/O access permissions), and ring 3 for unprivileged code (nearly all user programs). Under DOS, the kernel, drivers and applications typically run on ring 3 (however, this is exclusive to the case where protected-mode drivers or DOS extenders are used; as a real-mode OS, the system runs with effectively no protection), whereas 386 memory managers such as EMM386 run at ring 0. In addition to this, DR-DOS' EMM386 3.xx can optionally run some modules (such as DPMS) on ring 1 instead. OpenVMS uses four modes called (in order of decreasing privileges) Kernel, Executive, Supervisor and User.
The original Multics system had eight rings, but many modern systems have fewer. The hardware remains aware of the current ring of the executing instruction thread at all times, with the help of a special machine register. In some systems, areas of virtual memory are instead assigned ring numbers in hardware. One example is the Data General Eclipse MV/8000, in which the top three bits of the program counter (PC) served as the ring register. Thus code executing with the virtual PC set to 0xE200000, for example, would automatically be in ring 7, and calling a subroutine in a different section of memory would automatically cause a ring transfer.
The hardware severely restricts the ways in which control can be passed from one ring to another, and also enforces restrictions on the types of memory access that can be performed across rings. Using x86 as an example, there is a special[clarification needed] gate structure which is referenced by the call instruction that transfers control in a secure way[clarification needed] towards predefined entry points in lower-level (more trusted) rings; this functions as a supervisor call in many operating systems that use the ring architecture. The hardware restrictions are designed to limit opportunities for accidental or malicious breaches of security. In addition, the most privileged ring may be given special capabilities (such as real memory addressing that bypasses the virtual memory hardware).
