Solution 1 – Check your antivirus software

If you’re getting error code 0x8024402f, the problem might be related to your antivirus software. Certain antivirus tools can interfere with your security policies and prevent Windows Update from working properly.

To fix this problem, it’s advised to check your antivirus configuration and disable any security features that might interfere with Windows Update. If you can’t find those features on your own, you might want to try disabling your antivirus. Many users reported issues with Kaspersky antivirus, but after disabling it, the issue was resolved.

In some cases, you might even have to remove your antivirus entirely. If your current antivirus is causing this error to appear, you might want to consider switching to a different antivirus solution. There are many great antivirus applications on the market, but the best are Bitdefender, BullGuard and Panda Antivirus, so if your antivirus is causing this problem, be sure to try one of these tools.


Solution 2 – Run Windows Update Troubleshooter

You can always try Microsoft’s Update Troubleshooter. This tool is created for solving problems with Windows Updates, and it could solve yours as well. All you have to do is to download it, open it and let it find and (maybe) solve your update issues. If you’re still facing the same issue, after running the Troubleshooter, you should check your internet connection.


Solution 3 – Check your internet connection

0x8024402f is an error code related to connection problems with Windows Update. That means your computer isn’t able to connect to Microsoft Update server, therefore you’re unable to receive any new updates. So you either have a problem with internet connection, or Microsoft Update server is corrupted. If Microsoft Update Server causes problems, you just need to wait a little bit, because Microsoft’s staff will probably solve the problem quickly.

But if your internet connection is an issue, here’s what you should do:

  1. Go to Search and enter identify and repair. Open Identify and repair network problems.

After removing the latest update, check if the problem still persists. If not, you might want to block that update from installing. Windows 10 installs missing updates automatically, but there are few ways to block Windows 10 from installing automatic updates.


Solution 5 – Remove temporary files

Windows 10 uses temporary files for various operations, but if your temporary files are corrupted, you might encounter certain issues. Users reported that error code 0x8024402f can appear due to corrupted files, and in order to fix the problem, you need to remove those files.

There are several ways to remove temporary files, and doing that manually can be a long and tedious process. However, Windows comes with a useful tool called Disk Cleanup that can easily remove temporary files with ease. If you want to learn more about Disk Cleanup, we advise you to check out our guide on how to use Disk Cleanup and see how to easily remove temporary files.

In addition to Disk Cleanup, many users are recommending to use CCleaner instead. This is a third-party tool that can remove temporary and junk files from your PC with ease. In addition, this tool also has some advanced features that you might find useful, so feel free to try it out.


Solution 6 – Check your router’s firewall

According to users, sometimes your router’s configuration can cause this problem to appear. Users reported that error code 0x8024402f occurs if ActiveX controls are blocked in your router’s firewall.

To fix this problem, simply open your router’s configuration page, locate ActiveX blocking or filtering and disable this feature. After doing that, the problem should be resolved and you’ll be able to use Windows Update again.

To see how to disable this feature, we strongly advise you to check your router’s manual for detailed instructions.


Solution 7 – Reset your gateway/modem/router

As previously mentioned, your router configuration can cause this problem to appear. If you’re getting error code 0x8024402f on your PC, the issue might be caused because the router is set to work in bridge mode.

To fix the problem, set your router to work in default mode and the issue should be resolved.

Users reported this problem with Comcast devices, but the problem might occur with other devices as well.


Solution 8 – Try using a VPN

If you’re constantly getting error code 0x8024402f, the problem might be related to your ISP. Sometimes ISPs can block certain servers and prevent you from downloading updates. If this happens, you might want to try contacting your ISP and check if that solves the problem.

If you don’t want to contact your ISP, you might be able to solve this issues by using a VPN. We covered various VPNs in the past, and if you’re looking for a reliable VPN, we recommend CyberGhost VPN (77% off). After installing and using a VPN tool, the issue should be completely resolved.
