Dear CVI users,
if you are using NI Update Service please be aware that all downloaded updates remain on disk even after installation. After one or two years this may easily reach 10 GB of disk space if one is also using DAQ and other drivers.
I found out only yesterday - the updates are located in Program Data/National Instruments/Update Service/Installers/.
If NI is listening I would suggest adding an option to Update Service to remove these folders after successful installation of the update.
