Windows 11 24H2 Update Issues in 2026: Every Known Problem and Fix (Updated May 2026)

Last Updated: May 24, 2026

If you’re hitting a Windows 11 24H2 update issue right now, you’re not alone—and in May 2026, the situation is more complicated than ever.

The most urgent problem affecting users across the US, Europe, and India is error 0x800f0922, which is causing the mandatory May Patch Tuesday update KB5089549 to fail mid-installation and roll back, leaving systems unpatched and vulnerable.

But that’s not the only 24H2 problem you need to know about. Microsoft has been issuing emergency out-of-band fixes throughout 2026 for issues ranging from Microsoft account sign-in failures, Samsung device drive access errors, and boot loops triggered by the April update.

• According to Microsoft’s official documentation, common causes include incompatible drivers, insufficient storage, or corrupted system files. If your Windows 11 24H2 update failed, the first step is to ensure your device meets the minimum system requirements, including 64GB of storage and a compatible TPM 2.0 chip.
• For users facing persistent Windows 11, version 24H2 issues, Microsoft has released a Windows 11 24H2 repair version designed to address installation problems. This repair version can be downloaded via the Media Creation Tool or the Windows Update Assistant, offering a streamlined way to resolve errors.
• Experts recommend backing up your data before attempting a repair, as the process may involve reinstalling the OS. If your Windows 11 version 24H2 installation gets stuck during the process, you should boot into Safe Mode and run the Windows Update Troubleshooter.
• For advanced users, the Deployment Imaging Service and Management Tool (DISM) can effectively repair the Windows image. Always refer to Microsoft’s official support pages for the latest guidance, ensuring a secure and error-free installation.

Adding urgency: Windows 11 24H2 Home and Pro editions will reach their end of support on October 13, 2026. After that date, there will be no security patches or bug fixes. Microsoft is already force-upgrading unmanaged devices to Windows 11 25H2.

In this updated guide, I’ll walk you through every known Windows 11 24H2 issue logged in 2026, the confirmed fixes for each, and what you need to do before that October deadline. Let’s get your system sorted.

Windows 11 24H2 End of Support: What You Need to Know First

Before diving into the fix list, this context matters: Windows 11 version 24H2 (Home and Pro editions) will reach end of support on October 13, 2026. After that date, Microsoft will stop issuing security updates, bug fixes, and time zone updates for devices still on 24H2.

When Does Windows 11 24H2 Lose Support?

The official end-of-support date is October 13, 2026—confirmed in Microsoft’s documentation on Windows release health. This means you have approximately five months from today to either:

• Upgrade to Windows 11 25H2 (the Windows 11 2025 Update), or
• Accept being on an unsupported, unpatched OS

Microsoft confirmed in April 2026 that it has expanded its machine learning-based rollout of 25H2 to all unmanaged Windows 11 Home and Pro 24H2 devices. If your PC is not managed by an IT department, 25H2 is likely already downloading in the background.

Should You Upgrade to Windows 11 25H2?

For most users, yes. The excellent news: 25H2 is delivered as a small enablement package (under 200KB) because the code was already pre-staged on 24H2 systems through regular monthly updates. A single restart activates it.

The negative news: the April 2026 update KB5083769 caused boot loops on some systems during the 25H2 transition. If you’re affected, please consult the fix section below before you upgrade.

⚠️ BREAKING: KB5089549 Fails with Error 0x800f0922 (May 2026)

This is currently the most urgent issue regarding the Windows 11 24H2 update. Microsoft’s mandatory May 12, 2026, Patch Tuesday update (KB5089549) is failing to install on a subset of Windows 11 24H2 and 25H2 devices.

Microsoft officially confirmed the issue on May 15, 2026, three days after the update’s release.

Uninstall Windows 11 updates

What you see when affected:

• Update installs normally, then fails during the reboot phase at ~35–36% completion
• Windows rolls back the update
• Error message: “Something didn’t go as planned. Undoing changes.”
• Error code: 0x800f0922

What Causes Error 0x800f0922?

The confirmed root cause is insufficient free space on the EFI System Partition (ESP)—a small, hidden partition on your drive that stores critical boot files.

Specific threshold: Devices with 10MB or less of free space on the ESP are most likely to fail.

The EFI system partition is a hidden partition that most users never see. Your C:\ drive might show hundreds of GB of free space, and the update will still fail because the ESP—which Windows doesn’t display in File Explorer—is too full.

CBS.log entries on the affected systems show the following:

• ServicingBootFiles failed. Error = 0x70
• References to insufficient free space on EFI System Partition

Microsoft now recommends at least 15–20MB of free space on the ESP for seamless update installation.

How to Fix Error 0x800f0922 — Step-by-Step

Option 1: Restart and retry (works for most home users)

Microsoft issued a Known Issue Rollback (KIR) for this bug. For most home users on unmanaged devices, simply restarting your PC and checking for updates again is enough to install KB5089549 successfully.

Step 1: Open Settings > Windows Update Step 2: Click “Check for updates.” Step 3: If the update appears, install it—the KIR should have resolved the failure

Option 2: Registry workaround (if Option 1 fails)

Step 1: Press Win + R, type regedit, press Enter Step 2: Navigate to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management Step 3: Create or modify the required registry value as documented in Microsoft’s KB5089549 known issues page. Step 4: Restart your PC, then retry Windows Update

Option 3: Apply KIR Group Policy (Enterprise/IT admin users)

Step 1: Go to Microsoft’s Windows 11 24H2 or 25H2 release health page. Step 2: Locate KB5089549. In the Known Issue Rollback section, download the Group Policy MSI. Step 3: Double-click the MSI and follow the installation wizard. Step 4: Restart your devices to apply the Group Policy setting

What to Do If the Fix Doesn’t Work

If you’re still hitting 0x800f0922 after the above steps:

• Microsoft has not yet issued a permanent fix (no ETA provided as of May 22, 2026)
• Check C:\Windows\Logs\CBS\CBS.log for specific error entries
• Consider delaying the update temporarily—your system rolled back safely, so you’re not at risk from the failed install itself
• Monitor Microsoft’s Windows release health dashboard for the permanent fix announcement

Windows 11 24H2 Installation Problems: Why Your Update Is Stuck or Blocked

Safeguard Holds—What They Are and How to Check

A safeguard hold is Microsoft’s mechanism for blocking updates on devices with known compatibility issues. If your device has a safeguard hold applied, Windows Update will not offer certain updates until Microsoft confirms compatibility.

How to check: Go to aka. ms/WindowsUpdateBlockedDownloads to see if a hold is affecting your device.

In most cases, you should not try to bypass a safeguard hold manually—it exists to protect your device from a known breaking issue.

Update Stuck at Percentage — What to Do

If your update is stuck at a specific percentage for more than 2 hours:

1. Wait—some updates (especially with Secure Boot changes like KB5089549) take longer than expected
2. If stuck for 3+ hours: force restart by holding the power button
3. Windows will roll back the update safely on next boot
4. Run the Windows Update Troubleshooter and retry
5. If repeatedly stuck: run SFC and DISM (Fix 3 above) before retrying
