since it’s few updates to be applied, I came up with a script that will apply all of them in one go and you will need to reboot your server after applying all updates.

Create “installupdate.bat” within your update folder and the place following lines

ECHO: Installing KB2919442
START /WAIT ./Windows8.1-KB2919442-x64.msu

ECHO: Installing KB2919355
START /WAIT ./Windows8.1-KB2919355-x64.msu

ECHO: Installing KB2932046
START /WAIT ./Windows8.1-KB2932046-x64.msu

ECHO: Installing KB2937592
START /WAIT ./Windows8.1-KB2937592-x64.msu

ECHO: Installing KB2938439
START /WAIT ./Windows8.1-KB2938439-x64.msu

ECHO: Installing KB2934018
START /WAIT ./Windows8.1-KB2934018-x64.msu

ECHO: Install complete – press any key to reboot.
shutdown.exe /r /t 0

we can have a look at Event Log –> Windows Logs –> Setup and verify whether all updates were successfully applied.
