An alternative title might be "How to write a simple batch file to make Google Calendar Sync run at the same time as Outlook".

Create a text file (.txt). Use this syntax:

rem Outlook
cd "C:\Program Files\Microsoft Office\Office12"
start "" "C:\Program Files\Microsoft Office\Office12\OUTLOOK.EXE" /recycle
rem Google Outlook sync
cd "C:\Program Files\Google\Google Calendar Sync"
start "" "C:\Program Files\Google\Google Calendar Sync\GoogleCalendarSync.exe"

Change to .bat file afterwards. The empty double quotes thing when using 'start' tripped me up initially.

There's plenty of stuff online about this, such as these two links (a and b).

This all came about because Google Calendar Sync is keen to run when the computer starts up. The only problem with that occurs when it tries to sync before you've opened Outlook. You're prompted to enter your Outlook password (if one applies), then re-enter it if/when you log in to Outlook later.
