An error occurred while searching for your computer.
Code 8024402C Windows Update encountered an unknown error.
This Windows 8024402c update error is caused by incorrect proxy or firewall settings that prevent Windows update services from connecting to the Internet.
Here are some methods to help you solve this problem:
Resetting proxy settings
This solution can be very useful because it can be easily executed and can solve the problem by resetting the proxy settings on your computer that have been corrupted since the last time you performed the update. Follow the instructions below to solve the problem.
Use Windows + X to open the menu from which you must select the Command Prompt (Admin) option. You can also right-click on the Start menu for the same effect, or simply find the command prompt, right-click and select Run as administrator.
Enter the commands listed below and be sure to press Enter after each command to execute it correctly.
Return to Windows Update and check if the problem persists on your PC.
Change your DNS address
If your ISP is really causing these problems, other solutions may not be useful because they cannot resolve the fact that your current DNS address is simply not compatible with Microsoft servers. Fortunately, changing the DNS address is very simple if you follow these instructions carefully. You can easily cancel the operation if something goes wrong.
Open the Run dialog box by simultaneously pressing the Windows logo button + the R button. Then enter “ncpa.cpl” and click OK.
Now that the Internet Connection window is open, double-click your active network adapter.
Then click Properties and double-click Internet Protocol Version 4 (TCP/IPv4).
Search Use the following option for DNS server addresses.
Set the preferred DNS server to 126.96.36.199.188.8.131.52.184.108.40.206.
Set the alternative DNS server to 220.127.116.11.18.104.22.168.
Disable antivirus software
Temporarily disable the security software and check if the problem persists.
a : Press the Windows + Q logo to open the search field.
b : Now click Settings, then enter Action Center, press Enter.
c : Click on the chevron next to Security.
d: Disable the antivirus protection installed on your computer.
Warning: Antivirus software can protect your computer from viruses and other security threats. In most cases, you should not disable your antivirus software. If you need to temporarily disable it to install other software, you should reactivate it when you are finished. If you are connected to the Internet or a network while your antivirus software is disabled, your computer is vulnerable to attacks.
It is very easy to follow this procedure:
Open the registry editor (Start menu -> Run -> Regedit).
Find the following path HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU
Set the UseWUServer value from 1 to 0 (double-click it, change the value and click OK).
Restart the Windows Update service (Start menu -> Run -> services.msc, locate the Windows Update service and click Restart).
If you still can’t update Windows, there may be other reasons.
