3] Scan Your System For Viruses and Malware

  • Select Update and Security > Windows Security.

  • If your device discovers any malware, hit on the remove option.

Following this way, you can easily get rid of the viruses that are blocking Windows Update from occurring smoothly. 

4] Manually Reset Windows Update Components

In case you are still facing troubles updating your operating system, this might be due to the accumulation of cache inside the Windows Update folders. To solve this, you must reset Windows Update Components to their default state. 

5] Register System Files

In quite a few scenarios, corrupted registry files may also prohibit Windows update from installing new security patches. If that’s the case, you need to repair the registry following these simple steps –

  • Open Command Prompt as an Administrator. 
  • When the UAC window prompts, hit Yes to authorize accessing the black prompt. 
  • On the elevated console, execute these two codes –
regsvr32 Qmgr.dll /s
regsvr32 Qmgrprxy.dll /s
  • Make sure to press the Enter key after each command. 
  • When the codes run successfully, close CMD, and restart your PC. 

Now, once again try installing pending updates and see if it works.  

6] Clean Boot Your Device

At times, the presence of faulty third-party apps may also cause such errors on the computer. You can’t be sure of that by booting into your device normally. So, boot into the Clean State and check if you encounter the same error while updating Windows 10 or not. 

If you can install pending updates normally, the problem may lie with the third-party apps or services. Though you have successfully installed the security/non-security patches this time, the update error 80004002 may occur the next time. So, in order to solve this, get rid of all currently installed programs or see if there are any updates available for the respective applications or not. In case it does, download and install the same into your device.
