Fix: Windows Update Error 0x8024402f

Microsoft releases Windows Updates quite frequently. Most of these updates contain fixes and latest features. However, sometimes you might see an error while trying to install/download Windows Updates. The error message that you’ll see will be something like this

This error message will obviously prevent the user from updating the Windows.

This error occurs when some of the CAB files gets corrupted. There can be multiple reason of corruption but most likely one is that your ISP has caches the Microsoft Updates (so it doesn’t have to download it over and over) and some of those files got corrupted.

Make sure your Antivirus application is turned off or disabled. Every antivirus application has a disable option in its main panel or in settings. Antivirus applications have known to cause issues with the Windows Updates.

Method 1: Reset Windows Update Components

18. Type net start cryptsvc and press Enter

Now, restart and try to install the Windows Updates again

Method 2: Change Windows Update Settings

Although we aren’t sure why changing some specific settings from the Windows Settings panel solves this issue but it seems to work for plenty of users. So, follow the steps given below to change the update settings from Windows Update.

1. Hold Windows key and press I
2. Click Update & Security

3. Click Advanced Options

4. Uncheck the option Give me updates for other Microsoft Products when I update Windows

Note: In some cases, you might not be able to change this setting (as you can see it is disabled for me). You should just skip to the next method if that’s the case

That’s it. Once done, your problem should be solved.

Method 3: Change Proxy Settings

Changing the proxy settings has worked for a lot of users. Since the problem can be caused by ISP’s corrupt cache, changing the proxy settings works. Although the usual way of changing the proxy is to change it via the Windows Settings page but that doesn’t work for every user. A lot of users mentioned that it doesn’t update the Proxy settings. However, you can still try to change the settings via the Windows Settings. If that doesn’t work then move to the next section within this method. The second section requires command prompt so that might be a bit technical for a lot of users. So, we will advise you to use the Windows Settings first because there’s no need to deep into the command prompt if you can solve the issue with just a few licks.

Follow the steps given below to change the proxy settings via the Windows Settings

1. Hold Windows key and press I
2. Select Network & Security

3. Click Proxy from the left pane

4. Turn On the option Use a proxy server
5. Type the Proxy Server IP Address and Port number
6. Click Save and try again.

If the above steps didn’t solve the issue then do the following:

1. Press Windows key once
2. Type command prompt in the Windows Search box
3. Right click command prompt from the search results and select Run as administrator

4. Type netsh winhttp show proxy and press Enter
5. This will show you the current proxy settings

6. Now, you have to change the proxy settings via command prompt
7. Type netsh winhttp set proxy proxy-server=”your address”:”port number” and press Enter. Type the Proxy server IP address in your address part and type the port number in the port number part. Don’t forget to remove the quotes as well. At the end, it should look like this netsh winhttp set proxy proxy-server=123.154.165.11:8080

This should change your proxy settings and your Windows updates should work fine.

Method 4: Change Windows Update Service

Setting the Windows Update Service to Delayed Startup has been fruitful for a lot of users as well. So, if nothing else works then you should give this a go as well.

1. Hold Windows key and press R
2. Type services.msc and press Enter

3. Locate and double click the Windows Update service

4. Select Delayed Start from the drop down menu in Startup Type

5. Click Start if the Service Status is stopped
6. Click Apply then select Ok

Once done, try to update the Windows. It should work fine now.
