Windows 12 Remains Unannounced as Reports Point to Major Windows 11 27H2 Upgrade

That question drives Tom Warren's latest Notepad column at The Verge. He argues that Microsoft has a perception problem with Windows 11, and that a new version number won't fix it. His account of the next steps comes from unnamed sources. Here is what's confirmed, what's only reported, and what Windows users and IT admins can do today.

Microsoft is improving Windows 11 instead of renaming it​

Warren notes that Microsoft started planning in 2022 to go back to a three-year cycle for major Windows releases, with the first one landing in 2024. Many people expected that release to be Windows 12. It turned out to be Windows 11 version 24H2. The three-year mark is coming around again, and Warren reports that Microsoft is choosing to improve Windows 11 rather than put new features and plumbing under a Windows 12 name.

According to his sources:

• Windows 11 version 27H2 is already in preparation. Like 24H2, it would be a full OS swap that replaces or upgrades major parts of the system.
• 25H2 and 26H2 were enablement packages. They mostly switched on features that had already shipped in monthly cumulative updates.
• Insider testing could start early. A bigger release needs more testing, so Warren expects Windows Insider builds well before the June start Microsoft used for both 25H2 and 26H2.
• Quality is the main focus for the 2027 release.

Microsoft has not confirmed 27H2, its scope or its timing. Other outlets have reported much the same story, though. Windows Central's Zac Bowden reported that 26H1 and 26H2 sit on different Windows codebases, and that Microsoft is planning to bring everyone back onto the same platform release with version 27H2 in 2027. Bowden also said his sources describe it as the first platform release since 25H2 to be offered to the entire Windows 11 userbase. A previous WindowsForum analysis said the 27H2 claim had been independently reported by Windows Latest; not confirmed by Microsoft.

Microsoft's own documents back up the split. The release-information page shows 26H1 on OS build 28000 and 26H2 on build 26300. Microsoft says 26H1 supports new devices that started shipping in early 2026, is not a feature update for existing devices, and is not offered as an in-place update from 24H2 or 25H2.

On whether Windows 12 is coming, Bowden's answer is that we don't know. He also says a Windows 12 launch wouldn't rule out 27H2, because when Windows 11 version 21H2 debuted, Windows 10 still received its own 21H2 version that same year. In his view, it's better to get everyone back onto the same platform version under Windows 11 first, before trying to push forward with Windows 12.

Section summary: Windows 12 is unannounced. A larger Windows 11 27H2 in 2027 has been reported by several outlets but not confirmed by Microsoft. The fact that Windows 11 currently runs on two codebases is the strongest reason to expect a merge before any rebrand.

How 26H2 differs from what 27H2 might be​

The reported change in delivery method matters most to IT admins.

Microsoft describes an enablement package as a lightweight update that turns on features already delivered through earlier monthly updates. 26H2 shares its servicing branch with 24H2 and 25H2, so installing it feels much like a monthly update.

A full platform swap is a different job. Admins who remember the 24H2 rollout will expect more compatibility testing, more driver checks and more safeguard holds. Even 26H2, a minor update, came with its own known issues on Microsoft's release-health page:

• Credential Guard–protected machine accounts lost their secure channel with Active Directory. The September 22 update (KB5124010) fixed this.
• Desktops failed to load on Azure Virtual Desktop hosts using FSLogix. The October 13 update (KB5127648) fixed this.
• Non-admin users couldn't make Remote Desktop connections to hosts with Administrator protection turned on. The October 28 update (KB5127936) fixed this.
• Some USB Audio Class 1.0 devices fail with a Code 10 error. Microsoft lists this as still under investigation.

If an update this small brought that list, a full swap in 2027 will need careful pilot testing.

New wallpapers are reported, not confirmed​

Warren also reports that Microsoft plans to replace Bloom, the default Windows 11 wallpaper since launch. According to his sources:

• A set of new designs will be shown at Microsoft Ignite later this month.
• The designs keep Bloom's general look but use a folding sheet of color surrounded by clouds.
• Consumer and commercial editions get different versions. The Windows 11 Pro design is closest to Bloom's colors, and consumer variations are themed around gaming, productivity, creators and performance.
• Microsoft has already used some of the designs in recent marketing and plans a broad rollout in early January.

The Verge ran an image of one design credited to Microsoft. Microsoft hasn't said anything publicly about a schedule. Bloom was the face of Windows 11's launch campaign, so replacing it would be a visible way to mark a new phase without changing the version number.

The memory work: what Microsoft claims and how to get it​

Warren points to Microsoft's performance work as evidence of real progress, even though users find it hard to notice. Windows chief Pavan Davuluri published a post on the Windows Experience Blog on November 3, focused on PCs with 8 GB of RAM. Microsoft's main claims:

• Windows is up to 20% more responsive on 8 GB PCs. That figure comes from telemetry on Start, Search, right-click, Settings, Snipping Tool and File Explorer, comparing build 26300.9550 with 26200.7628.
• Multitasking is up to 40% faster in a single lab test on an HP OmniBook 3. Microsoft says the result is specific to that scenario and "not a benchmark."
• Up to 2 GB more active data stays in RAM instead of being paged to disk, thanks to retuned memory compression.
• Committed-memory growth is up to 900 MB lower across Windows, Edge and Microsoft 365 apps. Word, PowerPoint, Excel and Outlook account for about 360 MB of that.
• Background features use less memory. On PCs with 8 GB or less, Widgets now loads only when you open it, saving about 200 MB. Edge's sleeping-tabs default drops from two hours to 15 minutes.

Microsoft also notes that high memory use in Task Manager doesn't mean a PC is struggling. Responsiveness is the measure that counts. Warren adds that Windows Central tested the claims and found that recent Windows 11 updates do improve memory usage, while YouTubers and some Insiders remain skeptical.

These are mostly Microsoft's own numbers. Several come from telemetry or single-device lab runs, and the blog post ends with a holiday pitch for 8 GB laptops. Treat them as useful directional claims, not guarantees.

How to get the improvements​

1. Check your version: press Win + R, type winver, and press Enter. Microsoft says you need Windows 11 version 26H2, build 26300.9818 or later.
2. Open Settings > Windows Update.
3. Turn on Get the latest updates as soon as they're available.
4. Select Check for updates, then install 26H2 if it's offered.
5. Update Edge, Microsoft 365, Teams and Microsoft Store apps too, because some of the gains arrive through app updates.

If you're on 24H2 or 25H2 and 26H2 isn't offered, your device may have a safeguard hold. Check the 26H2 release-health page for open issues before trying to force the upgrade.

Other Windows news from the same column​

Warren's newsletter also covered smaller Microsoft items:

• Windows Search and Xbox mode: New Insider builds add search filters for files, actions and web results, plus quick actions such as changing brightness or volume. Xbox mode on handheld PCs gets quick settings for Bluetooth and Wi-Fi.
• Built-in network speed test: The taskbar speed test now runs inside Windows instead of opening a webpage. Marcus Ash, Microsoft's head of design and research for Windows and devices, says an agentic AI workflow built it, guided by one person in their spare time, and a working prototype took a day.
• Outlook search: Classic Outlook will fall back to a local index when the cloud connection is poor. A small language model will help rank results, and users get thumbs-up/down feedback buttons.
• Xbox PC app: A redesigned app that Microsoft says launches "up to 60 percent faster" is now available to Xbox Insiders.
• Opting out of AI scraping: OpenAI, Google, Microsoft and Anthropic have committed to a new robots.txt signal for blocking AI training. Microsoft says blocked sites will still appear in Bing results.

Analysis: is no Windows 12 a bad thing?​

Warren's argument is that Microsoft missed a chance to admit that Windows 11's ads were a mistake. He thinks the company is instead betting that steady fixes will win people back over time, and he doubts that's enough to get anyone excited about Windows again.

There's a case for Microsoft's approach. A new version number brings new hardware requirements, new upgrade paths and new support confusion, just after the end of Windows 10 support. Merging two codebases under the Windows 11 name is less exciting, but it's easier for IT departments to plan around.

Warren still has a point. Small memory savings are hard to see, while ads in the Start menu are easy to see. A new wallpaper can mark a fresh start, but it won't change how people feel about Windows 11.

What to do now:

• Home users: Install 26H2 at build 26300.9818 or later and keep your apps updated, especially on 8 GB machines.
• IT admins: Clear the 26H2 known issues now. Plan for 27H2 as if it were a full upgrade, with early Insider testing, driver and application checks, and a pilot group, even though Microsoft hasn't confirmed it.
• Everyone: Treat claims about Windows 12 as speculation until Microsoft announces something.
