Microsoft free anti-virus software MSE cannot be updated

Microsoft's free anti-virus software, Microsoft Security Essentials (MSE), has become a popular anti-virus tool for many friends. However, in actual use, there are also some problems that cannot be updated.

Failure to update anti-virus software poses a risk. Therefore, I will introduce two methods to solve the problem that MSE cannot be updated.

First:

Microsoft anti-virus software MSE cannot be upgraded, and the virus database cannot be updated. The error code is 0x80070422. For the code 0x80070422, Microsoft explains that it wants to check and start the following three services: automatically update the Automatic Updates (wuauserv) and Background Intelligent Transfer Service (BITS), DCOM server process initiator (DcomLaunch), the Startup type should be set to "automatic ". Run the following command:

SC config wuauserv start = autosc config bits start = autosc config DcomLaunch start = autonet stop wuauservnet start wuauservnet stop bitsnet start DcomLaunch

Second:

We can use the console to complete the update process. The update process is mpcmdrun.exe, which is located in the C: Program FilesMicrosoft Security Essentials directory.

Run-cmd,

Cd C: Program FilesMicrosoft Security essential tialsmpcmdrun-SignatureUpdate

After the prompt is complete, the virus database of the MSE is updated.
