Gl.iNet Reveal a Multi-Client KVM Management Device – the Comet X
GL.iNet has added the Comet X to its expanding Comet KVM range, with this model taking a more rack-focused approach than the earlier single-system units. Rather than being built around remote access to 1 machine, the Comet X is aimed at users who need to manage several nearby systems from a single KVM point, such as servers, workstations, test machines, or homelab hardware. It keeps the same general idea of browser and app-based remote control, but applies it to a 4-device setup with PoE support, local control options, and a chassis intended to fit more naturally into rack environments. At the time of writing, GL.iNet has shown the Comet X on its official pages, but has not confirmed a final price or general availability date
Hardware Specifications of the Comet X
The Comet X is built around a 4-system KVM layout, with 4 HDMI inputs for video capture and 4 USB-C device ports for connecting the controlled host machines. It also includes 1 HDMI output, allowing a local monitor to be connected directly to the unit rather than relying only on remote access through a browser or app. This is an important distinction from many smaller remote KVM devices, as the Comet X is not only intended to sit between a user and a remote machine, but also to act as a local switching and troubleshooting point when working directly at the rack.
For peripheral support, the unit includes 7 USB 2.0 Type-A host ports, rated at 5 V/0.5 A per port, which can be used for external peripherals and local interaction. Networking is handled through a 1GbE RJ45 port with 802.3af/at PoE support, while a USB-C power input is also available as an optional 5 V/3 A PD-compatible power source. This gives the device some flexibility in how it is deployed, although the presence of PoE is clearly one of the more rack-oriented parts of the design, as it reduces the need for a separate power adapter in suitable network environments.
Internally, the Comet X uses a quad-core ARM Cortex processor, 1 GB of DDR3L memory, and 64 GB of eMMC storage. The storage is intended for firmware, system use, and image storage, including ISO files for OS deployment or recovery tasks. The unit runs Linux 6.1 and supports up to 4K@30FPS video handling. It also includes a 3.69-inch TFT touchscreen on the front, which is used to show device status information such as IP details, online or offline state, and active sessions. Physically, the unit measures 170 x 90 x 40 mm, weighs 560 g, and includes brackets for both 10-inch and 19-inch rack mounting.

Software Features of the Comet X KVM
The Comet X uses GL.iNet’s GLKVM software platform, which is shared across the company’s current Comet KVM range. This allows connected systems to be accessed through a web browser or through GL.iNet’s own applications for Windows, macOS, Android, and iOS. The core purpose is to provide direct keyboard, video, and mouse access to the attached machines, including scenarios where the target system has no working operating system, no remote desktop service, or needs BIOS-level access. For server maintenance, OS installation, remote troubleshooting, and recovery work, this is the main difference between a hardware KVM and normal remote access software.
The GLKVM software also includes a number of management features that are relevant to a multi-system KVM setup. These include video quality adjustment up to 4K@30FPS, remote file transfer, audio output, virtual keyboard support, Wake-on-LAN, 2-factor authentication, and support for accessories such as ATX boards and Fingerbot devices. The Comet X also supports remote access methods including GL.iNet’s own access service, as well as Tailscale, ZeroTier, and NetBird, depending on how the user wants to expose or restrict access. This makes it possible to keep the device limited to a local network, integrate it into an overlay VPN, or use a more direct remote access method where appropriate.
Where the Comet X is more unusual is in combining remote KVM access, local KVM operation, PoE power, rack mounting, and control of up to 4 systems in 1 device. The current small remote KVM market is mostly built around 1 host system per unit, while traditional multi-port KVM switches are often focused on local switching rather than browser or app-based remote management. The Comet X sits between those categories. It is not just a remote dongle for 1 computer, and it is not simply a local HDMI and USB switch. Its main role is to provide centralized access to several nearby systems while still allowing remote control, local fallback access, touchscreen status information, and ISO-based recovery from the same unit.
GL.iNet Comet X vs Other Comet KVMs
The main difference between the Comet X and the rest of GL.iNet’s Comet KVM range is the number of systems it is designed to manage. Models such as the standard Comet, Comet PoE, Comet Pro, Comet 5G, and Comet Q are built around access to a single connected machine, with the exact feature set changing depending on the model. Some focus on compact remote access, some add PoE, some add stronger standalone hardware, and the Comet 5G adds cellular connectivity for fallback access. The Comet X changes the role of the device by moving from a 1-system KVM into a centralized 4-system unit.
That makes the Comet X less of a direct replacement for the other Comet models and more of a separate branch in the same product family. A single-system Comet device may still make more sense for users who only need access to 1 PC, NAS, mini PC, or remote workstation, especially where size, cost, or cellular failover matters more than managing several systems in 1 place. The Comet X is better aligned with rack or bench environments where multiple machines are physically grouped together and need to be accessed from 1 management point. Its trade-off is that some features found elsewhere in the Comet line, such as built-in 5G failover, are not currently listed for this model.

Price and Release Date of the GL.iNet Comet X
GL.iNet has not yet confirmed the final price or launch date for the Comet X. The official product listing currently presents the device as an upcoming quad-port remote KVM, and GL.iNet’s wider product pages also label the Comet X as upcoming rather than available to purchase. GL.iNet has also publicly referenced beta tester recruitment for the Comet X, which suggests the device is still in a pre-release stage rather than a finished retail launch. Until GL.iNet confirms availability, pricing, regional distribution, and whether there will be any early-bird or campaign pricing, the Comet X should be treated as announced but not yet released.

Microsoft released a new TeamViewer remote assistance connector for Intune in April 2026, replacing the older integration available since 2016. The new connector requires TeamViewer Tensor or a compatible enterprise license with a Microsoft add-on, and it requires the remote device to be actively managed by TeamViewer, not just enrolled in Intune. This article explains what changed, what you need to configure the integration, and what the new connector cannot do.
Windows Autopatch in the Intune admin center now includes an updated Secure Boot status report that provides device-level visibility into certificate readiness ahead of the 2026 expiry deadline. The report shows which devices have Secure Boot enabled, whether their certificates are up to date, and whether automatic or manual deployment applies. New columns for trust configuration, confidence level, and alerts help you make targeted decisions instead of broad deployments.
The May 2026 cumulative update KB5089549 added a new C:\Windows\SecureBoot\ExampleRolloutScripts folder containing seven PowerShell scripts. These scripts are part of Microsoft's sample toolkit for managing Secure Boot certificate migration across enterprise environments. This article explains what each script does, how to run it, and its limitations.
Microsoft has made Platform Single Sign-On (PSSO) during Automated Device Enrollment (ADE) generally available for macOS. The new EnableRegistrationDuringSetup setting in Microsoft Intune completes device registration and SSO configuration automatically during Setup Assistant — the initial macOS setup wizard — before the user ever reaches the desktop. This article explains what PSSO is, why the new setting matters, what you need to configure it, and what limitations to expect.
Microsoft Desired State Configuration (DSC) v3.2.0 reached general availability on April 29, 2026. DSC is a tool that lets you describe how a Windows or Linux system should be configured — services running, firewall rules in place, features installed — and then automatically apply or verify that configuration. Version 3.2.0 adds built-in resources for services, firewall rules, and SSH settings; extends the --what-if preview mode to individual resources; introduces version pinning; and includes experimental Bicep integration via gRPC. This article covers what changed, the limitations, and how to install the update.
Microsoft is introducing Cloud-Initiated Driver Recovery, a mechanism that automatically rolls back a faulty driver on your devices via Windows Update, without requiring any action from you or your hardware vendor. The feature is aimed at closing a gap where a bad driver could linger on devices for weeks before a fixed version became available. It works through the existing Windows Update pipeline and requires no new software on the client side. The feature is currently in a manual testing phase and is targeted for full automation in September 2026.
In a blog post titled 'Your Windows Update experience just got updated,' Microsoft has discussed its new mechanism to handle update installation failures on Windows 11: Windows now attempts to repair a failing update in real time during installation rather than rolling back immediately. This feature, called 'automatic recovery for update failures,' reduces the number of devices left in a failed-update state that requires manual troubleshooting. Administrators should note that this feature is distinct from—and should not be confused with—boot-level recovery, which is a separate safety net for devices that fail to start up after Patch Tuesday.
Microsoft Intune's April and May 2026 updates deliver three areas of practical change for administrators: richer and more frequent app inventory for Windows devices, a redesigned single sign-on (SSO) experience for Linux endpoints that replaces an aging authentication component, and automated enrollment support for Apple tvOS and visionOS devices in shared-use scenarios. Hotpatch updates — which apply security fixes without a restart — also become enabled by default for eligible Windows devices in May 2026.
TeamViewer is a remote assistance solution that lets you remotely connect to and control Intune-managed Windows, macOS, Android, and iOS/iPadOS devices directly from the Intune admin center to support your users. Microsoft Intune's April 2026 update (service release 2604) introduces a redesigned TeamViewer connector for remote assistance. The new connector replaces the existing one with a simplified setup process and adds SSO (single sign-on) support, device group synchronization, and granular role-based permissions. If you still use the old connector, you have 12 months to migrate before it stops working. This article explains what changed, what you need, and how to configure the new connector.
Windows 11 version 25H2 introduces a new Group Policy setting, Configure maintenance windows for automatic updates, that lets you define precise time windows for downloading, installing, and restarting after updates. The policy ships with version 3.0 of the ADMX administrative templates and is currently available only in Windows 11 Insider Preview builds. It takes priority over several existing update-related policies, but the interaction rules are only partially documented.
Starting in mid-April 2026, Microsoft allows you to upgrade Windows Server 2019 and Windows Server 2022 directly to Windows Server 2025 through Windows Update — no installation media (ISO file or DVD) required. The process is called an in-place upgrade, meaning your installed applications, settings, and server roles remain unchanged while only the operating system version changes. This article covers the prerequisites, the exact registry change you need to make, the step-by-step procedure for both the graphical desktop and the text-only Server Core installation, and the important cases where you must not use this method.
Microsoft released a new policy in April 2026 that lets you remove the Microsoft Copilot consumer app from managed Windows 11 devices using Group Policy or Microsoft Intune. The policy is called RemoveMicrosoftCopilotApp and is part of the April 2026 Windows security update. Alternatively, you can uninstall Copilot with PowerShell or Intune.
Microsoft is rolling out several long-requested changes to the Windows Update experience in Windows 11. You can now skip updates during initial device setup, pause them for up to 35 days with no limit on how many times you extend the pause, and restart or shut down your PC without being forced to install a pending update. Driver, .NET (Microsoft's application runtime framework), and firmware updates will be bundled into a single monthly restart cycle. These changes are currently rolling out to Windows Insiders in the Dev and Experimental channels.
Rufus is a free, open-source tool that creates bootable USB drives for installing Windows. Version 4.14 Beta, released on April 21, 2026, adds a new option to disable or remove preinstalled Microsoft apps such as Copilot, Teams, and Outlook during a fresh Windows installation. It also introduces a fully silent, unattended installation mode and an option to deploy a Secure Boot policy file at install time. This article explains what these new features do, how to use them, and where to be careful.
