The Windows 11 24H2 update (also called the Windows 11 2024 Update) has caused headaches for thousands of Melbourne PC users — from sluggish performance and boot failures to mysterious Wi-Fi drops and blue screen errors. This guide covers every confirmed issue, Microsoft’s latest patches, and step-by-step fixes you can try right now. If self-help isn’t working, Computer Cures’ Melbourne technicians are available 24/7.

Windows 11 24H2 Update Problems? Complete Fix Guide for Melbourne Users (2026)

What Is Windows 11 24H2?

Windows 11 24H2 — officially the Windows 11 2024 Update — is the second annual feature update for Windows 11, rolling out from October 2024. It ships with major changes including a new Recall AI feature, updated Copilot integration, Bluetooth 5.4 support, energy-saver improvements, and significant kernel-level changes that affect how hardware drivers behave. Microsoft began automatically pushing 24H2 to Windows 11 Home and Pro devices not managed by IT departments. If your Melbourne PC updated itself without your input, this is why.

Important — Windows 11 25H2 Now Available Microsoft released Windows 11 25H2 in late 2025. If you’re still on 24H2, many of the issues below have been patched. However, rolling to 25H2 introduces its own transition risks. Read our guide below before upgrading.

Credential prompt failures and session disconnects affected business users significantly.

Fix 1: Slow PC & Performance Issues After 24H2

This is the most widespread complaint from Melbourne users who installed 24H2 on older hardware (pre-2020 PCs). The update enables Windows Recall, Copilot+ background indexing, and enhanced telemetry — all of which consume resources even on systems that don’t meet Copilot+ requirements.

Before you start: check how much RAM you have. Windows 11 24H2 works best with16 GB RAM. If you’re on 8 GB or less, consider a RAM upgrade with Computer Cures to get a genuine performance boost.

STEP-BY-STEPSpeed Up Your PC After 24H2

  1. Press Ctrl + Shift + Esc → open Task Manager → click the Startup apps tab → disable all non-essential programs.
  2. Go to Settings → System → Power → set power mode to Balanced or Best performance.
  3. Open Settings → Privacy & security → Diagnostics & feedback → turn off optional diagnostic data and activity history to reduce telemetry overhead.
  4. Disable Windows Recall (if not on Copilot+ hardware): Settings → Privacy & security → Recall & snapshots → toggle off.
  5. Run Settings → System → Troubleshoot → Other troubleshooters → System Maintenance.
  6. Check for Windows Update patches: Settings → Windows Update → Check for updates — install all pending updates including optional driver updates.
  7. If slowness persists, book a PC Tune-Up with Computer Cures Melbourne — we’ll clean startup, check for malware, and optimise your system.

Fix 2: Boot Failures & Blue Screen of Death (BSOD) After 24H2

In late 2025 and early 2026, Microsoft confirmed a serious issue: the December 2025 cumulative update (KB5072033) could leave devices in an “improper state” after a rollback, causing subsequent Windows Updates to make the system unbootable. This affected physical devices running 24H2 and 25H2 — not virtual machines or home users in most cases. Microsoft’s BleepingComputer-reported fix confirms the issue is fully resolved in KB5077181 (released February 10, 2026). If your PC won’t boot at all, follow the recovery steps below.

STEP-BY-STEPFix Boot Failure / Won’t Start After Windows Update

  1. Force shutdown 3 times in a row (hold power button) to trigger Windows Recovery Environment (WinRE).
  2. In WinRE, choose Troubleshoot → Advanced options → Startup Repair. Let it complete.
  3. If Startup Repair fails, choose Advanced options → Uninstall Updates → Uninstall latest quality update.
  4. If still stuck, boot from a Windows 11 USB (create via Microsoft’s Media Creation Tool) and choose Repair your computer.
  5. Once booted, immediately go to Windows Update and install KB5077181 or the latest cumulative update to permanently resolve the bug.
  6. Still stuck? Our Computer Cures Melbourne repair team can recover your system and data without a full reinstall.
Data at risk? Never attempt a full Windows reinstall before backing up your files. If you can’t boot, our Melbourne data recovery service can extract files from an unbootable drive.

Fix 3: Wi-Fi & Bluetooth Problems After Windows 11 24H2

Network adapter drivers are one of the most common casualties of a major Windows feature update. The 24H2 update changed how Windows handles Wi-Fi drivers, particularly for Intel Wi-Fi 6 cards and Realtek adapters commonly found in Australian-market laptops.

Wi-Fi Disconnections / Cannot Find Network

STEP-BY-STEPFix Wi-Fi After 24H2

  1. Go to Device Manager (right-click Start → Device Manager) → expand Network adapters → right-click your Wi-Fi card → Update driver → Search automatically.
  2. If no update is found, visit your laptop manufacturer’s support site (e.g., Dell, HP, Lenovo, ASUS) and download the latest Wi-Fi driver for Windows 11.
  3. Forget and rejoin your network: Settings → Network & internet → Wi-Fi → Manage known networks → Forget your network → reconnect and re-enter the password.
  4. Run the built-in network troubleshooter: Settings → System → Troubleshoot → Other troubleshooters → Internet Connections.
  5. Open Command Prompt as Administrator and run: 
    netsh winsock reset
netsh int ip reset
ipconfig /flushdns

    Restart your PC afterwards.

  6. If your connection still drops, try resetting all network settings: Settings → Network & internet → Advanced network settings → Network reset.

Bluetooth Audio Drops & Device Disconnections

STEP-BY-STEPFix Bluetooth After 24H2

  1. Open Device Manager → Bluetooth → right-click your Bluetooth adapter → Update driver.
  2. If updating doesn’t help: right-click → Uninstall device → tick “Delete the driver software for this device” → restart. Windows will reinstall a fresh driver.
  3. Toggle Bluetooth off and on: Settings → Bluetooth & devices.
  4. For persistent audio stuttering, open Device Manager → Sound, video and game controllers → update your audio driver as well (Bluetooth audio uses both drivers).
  5. If using Bluetooth 4.x hardware, note that 24H2 optimises for Bluetooth 5.x — older devices may need a USB Bluetooth 5.0 dongle for reliable connectivity.

Fix 4: Start Menu, Taskbar & Explorer Crashes

In November 2025, Microsoft officially disclosed a major bug affecting virtually all core UI elements of Windows 11 24H2 — including the Explorer, Taskbar, Start menu, and the Shell Infrastructure host. The bug also appeared in 25H2. Microsoft later corrected its own workaround commands after discovering an error in the original fix script.

✅

This issue is resolved in cumulative updates from January 2026 onwards (KB5074105 and later). Installing the latest Windows Updates should permanently fix this problem.

STEP-BY-STEPFix Start Menu & Shell Crashes

  1. First, ensure all Windows Updates are installed: Settings → Windows Update → Check for updates. Install KB5074105 or later.
  2. If the Start menu crashes before you can open Settings, press Ctrl + Shift + Esc to open Task Manager → find Windows Explorer → right-click → Restart.
  3. To restart the Shell Infrastructure Host (sihost.exe): In Task Manager → find Shell Infrastructure Host → End Task → it should restart automatically.
  4. If the Start menu is completely non-functional, open PowerShell as Administrator and run: 
    Get-AppXPackage -AllUsers | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"}
  5. As a last resort, create a new Windows user account: Settings → Accounts → Other users → Add other user. Test if the Start menu works on the new account. If it does, the issue is profile-specific.

Fix 5: Display Flickering, Black Screen & Graphics Issues

Melbourne users with NVIDIA, AMD, and Intel graphics cards have reported screen flickering, black screens on wake, and resolution resets after 24H2. This is overwhelmingly a driver compatibility issue — Windows 24H2 changed the display stack and older drivers don’t always adapt cleanly.

STEP-BY-STEPFix Screen Flickering & Graphics Issues

  1. Download the latest GPU driver directly from the manufacturer — not from Windows Update, which may deliver generic drivers:
  2. Right-click Desktop → Display settings → verify resolution and refresh rate are set correctly (especially on 144Hz or higher monitors).
  3. If using multiple monitors: disconnect all but the primary monitor, restart, then reconnect one at a time.
  4. Check for HDR conflicts: Settings → System → Display → HDR — try toggling HDR off if you experience flickering.
  5. Disable hardware-accelerated GPU scheduling (HAGS) if experiencing lag: Settings → Display → Graphics → Default graphics settings → Hardware-accelerated GPU scheduling → Off.

Fix 6: Application Crashes & Compatibility Issues

Many Melbourne users have found that business software, creative tools, and games — particularly older 32-bit applications — misbehave after 24H2. This is partly because 24H2 tightens security around application permissions and introduces stricter credential autofill rules.

STEP-BY-STEPFix App Crashes After Windows 11 24H2

  1. Update the crashing application to its latest version from the developer’s official site or the Microsoft Store.
  2. Right-click the app’s shortcut → Properties → Compatibility → tick Run this program in compatibility mode for Windows 10 → click Apply.
  3. Right-click the app → Run as administrator — some apps require elevated permissions after the security changes in 24H2.
  4. Check Windows Event Viewer for the exact error: press Win + R → type eventvwr → look under Windows Logs → Application for error entries matching the crash time.
  5. If a Microsoft 365 app is crashing, run a repair: Settings → Apps → Microsoft 365 → Modify → Quick Repair.
  6. For games, verify game files through Steam or the relevant launcher, and ensure your GPU driver is up to date (see Fix 5 above).

If you rely on business-critical software and need it working fast, Computer Cures’ small business IT support in Melbourne can diagnose compatibility issues on-site the same day.

Fix 7: Remote Desktop & Credential Prompt Failures

The January 2026 security update (KB5074109) introduced a hardened credential autofill policy, which broke Remote Desktop connections in Azure Virtual Desktop and Windows 365 environments. This particularly impacted Melbourne businesses using remote work setups.

✅

Resolved in out-of-band update KB5078127 (released January 24, 2026). If you installed this OOB update, RDP should function normally. Install the latest cumulative updates if you haven’t already.

STEP-BY-STEPFix Remote Desktop Credential Issues

  1. Install KB5078127 via Settings → Windows Update → Check for updates or download from the Microsoft Update Catalog.
  2. Ensure you’re using the latest Windows App (formerly Remote Desktop app) from the Microsoft Store.
  3. If autofill is still blocked, your admin may need to configure the Group Policy setting for credential prompt behaviour introduced in KB5074109.
  4. For business RDS environments: check with your IT admin about deploying the temporary registry workaround noted in Microsoft’s advisory — note this workaround will be removed in April 2026 updates.

How to Roll Back Windows 11 24H2 to Windows 11 23H2

If the fixes above haven’t resolved your issues, rolling back to the previous version of Windows is a viable option — but only within 10 days of the original update. After that, the rollback files are automatically deleted by Windows to reclaim disk space.

⬅️ Rolling Back Windows 11 24H2 (Within 10 Days)

  1. Go to Settings → System → Recovery.
  2. Under Recovery options, click Go back next to “Previous version of Windows”.
  3. Follow the prompts — your apps and files will be preserved, but apps installed after the update may be removed.
  4. After rollback, go to Windows Update → Advanced options → Pause updates to prevent automatic re-installation while you troubleshoot.
⚠️

Past the 10-day window?A clean install of Windows 11 23H2 is required. Back up all your data first. Computer Cures can perform a clean Windows reinstall in Melbourne with full data backup.

Should Melbourne Users Update to Windows 11 25H2 Now?

Frequently Asked Questions: Windows 11 24H2 Issues

Why is my PC slow after the Windows 11 24H2 update?

The 24H2 update introduces new AI background processes (including Windows Recall), expanded telemetry, and Copilot integration that all consume additional RAM and CPU. PCs with 8 GB RAM or less are most affected. Disabling Recall, reducing startup programs, and updating drivers usually resolves the issue. A RAM upgrade to 16 GB can also provide a significant boost — Computer Cures offers hardware upgrades across Melbourne.

How do I fix the Windows 11 24H2 boot failure?

Microsoft confirmed boot failures linked to the December 2025 cumulative update. The permanent fix is included in KB5077181 (February 10, 2026). If your PC won’t boot, force-trigger WinRE by holding the power button to shut down 3 times, then run Startup Repair. If that fails, boot from a Windows 11 USB and choose “Repair your computer”. See our detailed boot repair steps above.

Can I roll back Windows 11 24H2?

Yes — but only within 10 days of installing 24H2. Go to Settings → System → Recovery → Go back. After 10 days, the rollback option disappears. You would need a clean reinstall of Windows 11 23H2. Computer Cures can handle a clean reinstall with full data backup — book our OS reinstall service.

Why won't my Wi-Fi work after the Windows 11 update?

Windows 24H2 sometimes resets Wi-Fi adapter settings and can conflict with older drivers. The quickest fix is to update your Wi-Fi driver from your laptop manufacturer’s website, then forget and rejoin your Wi-Fi network. Running netsh winsock reset from an admin command prompt and rebooting also resolves most cases. See our full Wi-Fi fix guide above.

My screen is flickering after the Windows 11 24H2 update — what should I do?

Screen flickering after 24H2 is almost always a GPU driver issue. Download the latest driver directly from NVIDIA, AMD, or Intel’s official website (not Windows Update). Also check your refresh rate and HDR settings in Display Settings. See our complete display fix guide.
