Error code 0x80070005 refers to an error that occurs when the user lacks permissions to a registry or a file that is required during a Windows Update installation. This error is generally caused by a user not having administrative access to the files or by changes caused by malware.
Microsoft Support recommends that users attempt to install the Windows updates again while logged in as administrator in the computer. If installation continues to generate the 0x80070005 error, users are avised to use the SubInACL tool to attempt to repair permissions to the associated files or registry. After this repair process is completed, users can also scan their computer for malware that may have caused the error.
