My TZ21 is now about 3 years old and came with Vista pre-installed.
I have now upgraded to Windows 7.
Problem is that although most things work well the following do not:
Camera (Sony cal it motion eye)
SD card reader
I have read that Sony do not support the upgrade to W7 and despite Google searches, I can find little info on how to get the W7 drivers.
I have tried to use the original Sony setup disk but that does not work.
