You can find the Examples on bridge control panel in its installation folder. The path may look something like this:
C:\Program Files (x86)\Cypress\Programmer\Bridge Control Panel\1.20.0\Examples
Please check and update if it helps or not.
I don't think there are any prominent python I2C libraries developed for Windows. The most popular i2c python library I see is the SMBus but it is only available for Linux hosts. There are no examples of Python I2C implementations with the PSoC which we can provide.
