Easily Update to Windows 8.1 Update 1 without Installing all the MSUs Manually

If you are upgrading an existing Windows 8.1 installation to Windows 8.1 Update 1 through your MSDN account then you will need to find the following .zip package for x64.

After downloading it, you may get frustrated by installing all the MSUs manually from the .zip file as shown below.

You have to install them in a certain order as described in the ReadMe.txt and after each one, it prompts you to reboot.

There has to be an easier way:

Create a .bat file and place it in the same folder with all the .msu files with the name “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

After you double click the file the update will start, it will prompt  you with each file if you want to update or not. Select “yes” and don’t worry about rebooting after every update. Once this is complete, reboot your machine and you will have your system up and running on Windows 8.1 Update 1. 

If everything installed correctly, then you will see the following power and search buttons by your login name once restarted.

I hope this helps!
