7. Update your network drivers

If you’re experiencing network connectivity issues, you should check your network drivers since they might be outdated, especially if you still have the stock drivers because you never performed an update.

The quickest and safest way is to use a driver updating application for updating all obsolete drivers at the same time. However, if you don’t want to install any third-party programs, you can turn to Device Manager:

  1. Press Windows key + R, type devmgmt.msc, and press Enter
  2. Click the arrow button next to Network adapters to expand this group
  3. Right-click your network interface and select Update driverDevice Manager shows how to update network driver
  4. Click Search automatically for drivers and wait

If the online search doesn’t return anything, you can visit the manufacturer website of your network adapter in order to find, download and install the latest version. It’s risky, though, because you could accidentally set up an unsupported driver.

8. Roll back your network drivers

On the other hand, you might have accidentally downloaded and installed a driver that’s not compatible with your network adapter or operating system. It could hurt your entire Internet connections, so it’s better to roll back to the previous version. Here’s how:

  1. Right-click the Start button and select Device Manager
  2. Double-click your network adapter to access its properties
  3. Switch to the Driver tab
  4. Click the Roll Back Driver button and follow the step-by-step instructions

If you can’t click Roll Back Driver because the button is greyed out, it’s impossible to go through with the rollback because there’s no previous driver saved on your PC.

9. Unplug peripheral devices

Hardware components that were recently attached to your desktop or laptop might not fully support your operating system. In turn, this could affect your applications, Internet connections, and system tools like Windows Update, resulting in error 0x8024401c.

Consider any new pieces of hardware that you connected to your PC, like a webcam, a Wi-Fi adapter, a pen drive, or a memory card. Remove their cables, restart your computer, and check if you can run Windows Update. You should also try plugging the devices into other USB ports in case they are not working properly.

10. Reinstall devices

Another way to deal with peripheral devices is by reinstalling them on your Windows 10 PC. This is made possible through Device Manager since you just have to uninstall the adapters. After restarting your computer, Windows will make sure to automatically install all missing devices. Here’s what you need to do:

  1. Click the Start button, search for Device Manager, and press Enter
  2. Look for any devices with a yellow exclamation mark
  3. Right-click it and select Uninstall deviceDevice Manager shows how to uninstall network device

Your HDD or SSD might be experiencing hardware failure or bad sectors. It could affect your entire system, including the Windows Update service. But you can turn to CHKDSK (Check Disk) to find and fix any problems:

  1. Click the Start button, search for Command Prompt, and select Run as administrator (click Yes if prompted by UAC)
  2. Take into account the partition letter of Windows and enter chkdsk c: /f /r (if it’s not c:, replace it with the correct letter)
  3. CHKDSK will ask you to confirm scheduling the tool at the next Windows boot. Agree by typing y and pressing Enter
  4. Restart your PC and wait for CHKDSK to do its job

12. Fix corrupt system files

Windows 10 might have damaged, modified or missing files that are essential for Windows Update. Without taking measures, you will keep seeing error code 0x8024401c. But you can fix this problem by running DISM (Deployment Image Servicing and Management) and then SFC (System File Checker):

  1. Press the Win key, type CMD, select Command Prompt, and click Run as administrator
  2. Write DISM /online /cleanup-image /scanhealth and press EnterWindows 10 shows how to run DISM /online /cleanup-image /scanhealth in CMD

  5. Type sfc /scannow and hit the Enter keyWindows shows how to run the sfc scannow command in CMD
  6. Restart your workstation before trying Windows Update

13. Check firewall settings

Your firewall filters Internet traffic by allowing and denying access to processes and services. If you have accidentally messed up the firewall settings, this could explain why Windows Update throws you errors like 0x8024401c. Unless you have a third-party firewall tool installed, here’s what you can do with Windows Defender Firewall.

How to temporarily disable your firewall:

  1. Make sure you’re signed in with an admin account on Windows 10
  2. Click the Start button, type check firewall status, and press Enter
  3. Click Turn Windows Defender Firewall on or offControl Panel shows how to turn Windows Defender Firewall on or off

Instead, you can restore firewall settings to default, in order to undo any customized preferences that could’ve triggered the Windows Update error.

How to restore firewall settings to default:

  1. Press the Win key, type firewall, and open Firewall & network protection
  2. Scroll down to the bottom of the page and click Restore firewalls to defaultWindows Security shows how to restore firewalls to default
  3. Click Restore defaults and click Yes to confirm

A malicious agent could have hijacked your PC and deactivated critical files that Windows Update needs to work properly. Unless you have a third-party security solution installed, here’s how to find and remove malware using Windows Defender:

  1. Click the Start button, write Windows Security, and open this tool
  2. Pick Virus & threat protectionWindows 10 shows how to select Virus and Threat Protection
  3. Click Scan optionsWindows 10 shows how to access Windows Defender scan options

  7. Restart your PC

15. Uninstall recent software
