Summary

The Windows 11 24H2 update introduces several new AI features and security improvements, but like any major operating system update, it also brings a few annoying bugs. If your computer recently updated and things are acting strange, review this list of the most common 24H2 issues and their solutions.

Before You Start

• To check your Windows version, press Win + R, type winver, and press Enter.
• If winver reports Version 25H2 rather than 24H2, your machine has already moved to the next annual release and this article no longer applies to it — see Understanding Windows 11 25H2 — What Changed and What to Check instead.
• This version has a published end date. Microsoft lists Windows 11 Home and Pro, Version 24H2 as ending support on October 13, 2026, after which no new security updates are issued for it. The 25H2 guide above covers what that date means and how to read your own edition.

Instructions

1. The 8.63 GB "Undeletable" Windows Update Cache

The Bug: After updating to 24H2, if you run the Disk Cleanup tool to remove "Windows Update Cleanup" files, it will constantly report that there is an 8.63 GB file leftover that it cannot delete. The Fix: You do not need to do anything. Microsoft has confirmed this is a visual reporting bug in the Disk Cleanup tool itself. The 8.63 GB is not actually taking up space on your hard drive, and attempting to force-delete it using third-party tools can corrupt your Windows installation. Microsoft will fix the visual bug in an upcoming patch.

2. Fingerprint Sensors (Windows Hello) Stop Working

The Bug: Laptops with built-in fingerprint scanners suddenly fail to recognize your finger or report that "Windows Hello is not available on this device" on the lock screen. The Fix:

1. Open the Start Menu, type Device Manager, and press Enter.
2. Expand the Biometric devices category.
3. Right-click your fingerprint sensor (e.g., "Goodix Fingerprint" or "Synaptics") and select Update driver.
4. Choose Search automatically for drivers.
5. If that fails, go to your laptop manufacturer's website (Dell, Lenovo, HP), download the latest fingerprint driver for Windows 11, and install it manually.

3. Wi-Fi "No Internet, Secured" Connection Drops

The Bug: The Wi-Fi connects to the router successfully, but Windows reports "No Internet," or the connection randomly drops every few hours requiring a computer restart.

⚠ This step needs administrator rights

On a work computer you may not have these, and that is normal - it is not something you did wrong.

Why this one needs them: netsh winsock reset rewrites network settings the whole computer shares, so Windows refuses to run it from a standard account.

What it changes, and how to undo it: both commands clear cached network data that Windows rebuilds by itself, and the restart in step 4 below is what puts the rebuilt settings into use. Your saved Wi-Fi networks and their passwords live elsewhere and are not touched, so there is nothing to put back afterwards.

Rather not? How to Fix "No Internet, Secured" Wi-Fi Error on Windows 11 covers the same fault, and its Step 5 clears the DNS cache and renews your address from an ordinary Command Prompt with no admin rights at all.

Blocked? If Run as administrator is greyed out, or the prompt asks for a password you do not have, take that no-admin route first. If the fault survives it, raise a ticket saying your Wi-Fi connects but reports "No Internet" since the 24H2 upgrade, that flushing the DNS cache made no difference, and that you would like netsh winsock reset run on the device.

The Fix:

1. Open the Start Menu, type cmd, right-click Command Prompt, and select Run as administrator.
2. Type netsh winsock reset and press Enter.
3. Type ipconfig /flushdns and press Enter.
4. Restart your computer. This clears the corrupted network cache left over from the upgrade process.

4. Audio Stuttering When Playing Videos or Games

The Bug: Audio randomly pops, crackles, or stutters for a split second when listening to Spotify, watching YouTube, or on a Teams call. The Fix: This is often caused by outdated audio drivers clashing with the new 24H2 audio stack.

1. Right-click the Start button and select Settings.
2. Go to Windows Update > Advanced options > Optional updates.
3. Look for any pending Realtek, Intel, or AMD audio driver updates and install them.

Troubleshooting

TIP

If an issue completely prevents you from working, you have a 10-day window to roll back to the previous version of Windows 11 (23H2). Go to Settings > System > Recovery and click Go back. The version you land on has its own end date: on Windows 11 Enterprise and Education, and on Windows 11 IoT Enterprise, Microsoft lists Version 23H2 as ending support on November 10, 2026. On Windows 11 Home and Pro that support has already ended — Microsoft's list of products ending support in 2025 gives Version 23H2 an end of servicing date of November 11, 2025 — so on those editions a rollback lands you on a version that no longer receives monthly security updates. Roll back to get working again, then move forward to 24H2 or later once the fault is fixed.

Symptom / Error	Potential Cause	Solution
"Go back" button is missing in Recovery	Past the 10-day limit	Windows automatically deletes the backup of your old OS after 10 days. You must wait for Microsoft to patch the bug.
Blue Screen of Death (BSOD) during boot	Incompatible software	Some older anti-cheat software and VPN clients cause a BSOD on 24H2. Boot into Safe Mode and uninstall them.
