How do we turn off "iDrive almost full" notifications in Windows 7 Professional?

Since iDrive is not an Apple product, contact the makers of iDrive and ask them.

Here are the steps:

1. Click on the Start orb, then on Control Panel.
2. Select Appearance and Personalization, then under Taskbar and Start Menu, click on Customize icons on the taskbar.
3. Scroll down to iCloud Services and change the dropdown to Hide icon and notifications.
