Win8.1 Update update error 80070020, 80073712, 0x800f081f how to do

As of now, Win8.1 Update failed to have three error codes, such as 80070020, 80073712 and 0x800f081f, but Microsoft has not provided a temporary solution. Fortunately, Andrew B, a fan from the Microsoft community, offers a simple and practical fix that takes just two lines of commands.
Operation is as follows: (Win8.1 platform)
1. Log in to the traditional desktop, right click on the start menu, select command prompt (admin)
2, enter the following two commands:
• Remove the Win8.1 Update (KB2919355) update patch
dism /online /remove-package /packagename:Package_for_KB2919355~31bf3856ad364e35~amd64~~6.3.1.14
After uninstalling the update, the user needs to manually restart the system to complete the configuration
• After uninstalling the update, continue to clear the image file
dism /online /cleanup-image /startcomponentcleanup
3, when the operation is completed, we can get the Win8.1 Update update through Windows Update again.
