Understanding Windows 11 24H2: Common Bugs and Fixes ​

Estimated Time to Fix: 3 minutes

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.

Prerequisites ​

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. 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 The Fix: This is often caused by outdated audio drivers clashing with the new 24H2 audio stack.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.
