6. Check registry settings
Using Registry Editor, you should inspect some entries that affect Windows Update, in order to make sure that everything is in working order. Here’s what you need to do:
- Press Windows key + R, write regedit, and hit Enter to open Registry Editor. If prompted by UAC (User Account Control), click Yes
- Open the File menu and select Export
- Create a registry backup file by specifying the file name and saving directory
- Go to the following location:
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update
- Check whether or not EnableFeaturedSoftware exists. If so, ensure that Data is set to 0x00000001 (1). Otherwise, double-click its entry, set Value data to 1 and Base to Hexadecimal, then click OK
- However, if EnableFeaturedSoftware doesn’t exist, you must create it:
- Select Edit > New > DWORD (32-bit) Value
- Enter the EnableFeaturedSoftware entry and double-click it
- Set Value data to 1 and Base to Hexadecimal, then click OK
- Head over to this location:

- Set Value data to 1 and Base to Hexadecimal, then click OK
- Quit to the desktop
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If you’re experiencing network connectivity issues, you should check your network drivers since they might be outdated, especially if you still have the stock drivers because you never performed an update.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:
- Press Windows key + R, type devmgmt.msc, and press Enter
- Click the arrow button next to Network adapters to expand this group
- Right-click your network interface and select Update driver
- 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:
- Right-click the Start button and select Device Manager
- Double-click your network adapter to access its properties
- Switch to the Driver tab
- 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:
- Click the Start button, search for Device Manager, and press Enter
- Look for any devices with a yellow exclamation mark
- Right-click it and select Uninstall device
- Open the Action menu and choose Scan for hardware changes
- Reboot your Windows PC
11. Check your hard disk for errors
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:
- Click the Start button, search for Command Prompt, and select Run as administrator (click Yes if prompted by UAC)
- Take into account the partition letter of Windows and enter
chkdsk c: /f /r
(if it’s notc:
, replace it with the correct letter) - CHKDSK will ask you to confirm scheduling the tool at the next Windows boot. Agree by typing y and pressing Enter
- 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):
- Press the Win key, type CMD, select Command Prompt, and click Run as administrator
- Write
DISM /online /cleanup-image /scanhealth
and press Enter - If it finds any issues, run
DISM /online /cleanup-image /restorehealth
to fix them - Reboot your PC and launch Command Prompt with elevated rights
- Type
sfc /scannow
and hit the Enter key - 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:
- Make sure you’re signed in with an admin account on Windows 10
- Click the Start button, type check firewall status, and press Enter
- Click Turn Windows Defender Firewall on or off
- At Private network settings and Public network settings, select Turn off Windows Defender Firewall and click OK
Try to run Windows Update now. If it turns out to be a successful move, you shouldn’t keep your firewall disabled because it means leaving your PC vulnerable to malware attacks. 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:
- Press the Win key, type firewall, and open Firewall & network protection
- Scroll down to the bottom of the page and click Restore firewalls to default
- Click Restore defaults and click Yes to confirm
14. Run a malware scan
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:
- Click the Start button, write Windows Security, and open this tool
- Pick Virus & threat protection
- Click Scan options
- Select Quick scan and click Scan now
- If the scanner doesn’t find any threats, pick Windows Defender Offline scan and click Scan now
- Make sure to quarantine or remove any files identified as threats by Defender. If you think it makes a mistake, add those files to the whitelist to exclude them from further scans
- Restart your PC
15. Uninstall recent software
Programs you installed on your computer lately might cause software conflicts with Windows Update which culminate in error 0x8024401c. So you should uninstall any recent and suspicious applications, especially if you started experiencing Windows Update issues right after adding them to your PC. Here’s how:
- Right-click the Start button and select Apps and Features
- Click Sort by and select Install date to view recent programs first
- Select the first app in the list and click Uninstall
- Click Uninstall again to confirm
- Restart your computer
16. Uninstall system updates
Certain Windows updates can cripple your operating system and prevent it from accessing further updates. You should remove it from your PC to get rid of error code 0x8024401c. Here’s what you need to do:
- Press Win key + R, enter appwiz.cpl, and hit the Enter key
- Click View installed updates
- Click the Installed On column to view the newest updates first
- In the Microsoft Windows category, double-click the first update

17. Check the disk space
If you don’t have enough free space on the system drive, Windows Update won’t be able to download and install anything. But you can fix this problem by increasing the volume size with the help of a partition manager like Disk Management.
How to use Disk Management:
- Right-click the Start button and go to Disk Management
- Select a local drive where Windows is not installed
- Right-click the entry and choose Shrink Volume
- Set the new partition size and click Shrink
- Return to the main window and select the Windows partition

- Click Next and follow the steps
- Your PC will reboot after the system restore
20. Reset your PC
If System Restore fails to work, you can reset Windows 10 to factory mode without losing your personal files. However, this will uninstall all your applications and restore all computer settings to default, which means that you will have to spend a little time to set up your PC afterward. Here’s what you need to do:
- Press the Win key, search for Recovery options, and hit the Enter key
- At Reset this PC, click Get started
