Windows Update Standalone Installer
Installer encountered an error: 0x80070422
The service cannot be started, either because it is disabled or because it has no enabled devices associated with it.
Ensure that the Windows Update (wuauserv) service is not set to Disabled in order to proceed. Be aware that this is valid for running any MSU package for that matter where the former supersedes the MSI counterpart for software installation, including the application of hotfixes and patches in newer Windows versions.
Note that with the recent release 1.10 (19 Nov 2015) of RSAT, it now supports a number of languages besides US-English (en-US)
de-DE, es-ES, fr-FR, it-IT, ja-JP, ko-KR, pt-BR, ru-RU, tr-TR, zh-CN, and zh-TW
Installation of a supported language pack listed above is mandatory if the base Windows 10 OS UI does not match any of the listed languages.
