Microsoft rolled out Windows 8.1 Update 1 to MSDN subscribers yesterday, as part of the company’s big unveiling of the update during the Build 2014 Developer Conference. For those who are familiar with the recent registry tweak that allowed you to snag the update via Windows Update, you might have been frustrated installing the update files one by one.
Michael Crump has provided an easy solution for those who have the update downloaded via MSDN and want to avoid the frustrations of installing each .MSU file one by one. The best way to install the update with ease is to create a .BAT file and place it in the same folder as the .MSU files. Name the .BAT file “InstallUpdate.bat” and place the following code inside of it:
@ECHO OFF
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 KB2949621
START /WAIT Windows8.1-KB2949621-v2-x64.msu
ECHO: Install complete – press any key to reboot. Pause shutdown.exe /r /t 00 exit
Pause
shutdown.exe /r /t 00
exit
Once you place the .BAT file consisting of the content above, double click the file and let the update begin. You will be prompted to install each update, so click “Yes” and let the update install in order. Reboot your computer after all the updates have been installed. Enjoy Windows 8.1 Update 1!
