Solve MSE, Windows Update/defender cannot be updated (error code 0x8024402f)

 

I installed an MSE on my home desktop yesterday and found it could not be updated.Code0x8024402f. As a result, a large number of information solutions are collected.

So I carefully studied and collected a lot and found that this error exists extensively. I would like to summarize the solutions here to help more people.

This error is caused by a variety of online comments. Some people say it is a service startup problem, some say it is a network environment problem, and some people have pushed the responsibility to the "guard", which has been planted everywhere ...... Regardless of him, let's solve it together:

Solution 1: start the service item.The error 0x8024402f occurs because "used for smart Transmission Service (BITs)" is not properly started. BITs is used to transmit files in the background using idle network bandwidth. If the service is disabled, functions such as Windows Update and MSN Explorer cannot be automatically downloaded.ProgramAnd other information. If this service is disabled, any service dependent on it may not be able to transmit files directly through ie without fault tolerance. Once bits is disabled, files may not be transmitted.

Open the Service (Control Panel-Administrative Tools-service, or start searching for "service"), find "Background Intelligent Transfer Service", and double-click the service, and set it to "automatic" to update the system normally.

The default service item of the author is "automatic (delayed startup)", and cannot be updated after it is changed to "automatic ......

 

Therefore, solution 2: Microsoft answers forum for solutions. The moderator provides the following answers:

0x8024402f the error code indicates a network connection error. This may be a temporary regional issue. If it can be updated before, it is recommended that you try again later.

If you have set up a proxy, temporarily remove the proxy and try again.

If you use a vro to access the Internet, skip the route temporarily and connect directly to the network to check whether the network can be updated.

If you have installed other anti-virus software and firewalls, uninstall them and try again.

If it is on the campus network or the company's Lan, change the network environment or manually download the update:

1. For a 32-bit system, visit the following link:

Http://go.microsoft.com/fwlink? Linkid = 87342

For a 64-bit system, visit the following link:

Http://go.microsoft.com/fwlink? Linkid = 87341

Download and save the file to the desktop.

2. For Windows XP system, double-click the downloaded file to install it.

For Windows 7 or Vista, right-click the saved file and choose "Run as administrator ".

3. After the update is complete, you can go to the "Update" tab of Microsoft Security essential to confirm the version and update time of the definition library.

Moderator solution 2: Set DNS (this method basically solves all the errors). I personally tested that both computers are valid.

The manual update method provided above is only to actively download and install the update file of the virus and spyware definition library, so it only solves the problem of virus library expiration.

To solve network problems, try the following methods:

1. Click Start> Control Panel> network and sharing center ".

2. Click "Change adapter Settings" in the left-side navigation bar ".

3. Right-click the current network connection (local connection or broadband connection) and select "properties ".

4. Select "Internet Protocol Version 4 (TCP/IPv4)" and click "properties ".

5. In the Internet Protocol Version 4 (TCP/IPv4) Properties window that appears, select "Use the following DNS server" for manual settings.

6. Enter 4.2.2.1 In the preferred DNS server and 4.2.2.2 in the backup DNS server.

7. After completing the settings, connect to the Internet again and try to update it to check whether the update is successful.

Therefore, MSE can be updated normally!
