After a few months experience, we are able to conclude that all recent versions of WinGPS are fully compatible with Windows 7. An advantage of Windows 7 is (a.o.) the very quick start up.

If you wish to use a USB GPS receiver however, you need to install a special Windows 7 driver.
With most GPS receivers, these are not included in the package. You may download an updated driver for XP, Vista and Windows 7 of our website at Support/Downloads and then COM POORT SOFTWARE.
