If you can flash and talk to the unit with the current driver's, don't change anything.?

I have searched the site and did not find a relevant message for my question.
I did connect the nanovna usb cable to the Win7 laptop before installing the new driver - which may have been a mistake. Windows did install a driver. Device Manager identified the driver as STMicroelectronics, 24/04/2010, driver version 1.3.1.0.
I downloaded and installed the STM version 1.5.0 driver installation software. Windows said the installation was successful. Device manager still showed driver as the 1.3.1.0 2010 version. Restart had no effect.
Nanovna-saver installed and works fine.
DeFuseDemo installed, recognized the Nanovna in DFU mode (even though it does not show up in Device Manager when in DFU mode), and upgraded firmware to 1.0.64.
So, as far as I can tell from the above, the device is connecting to the Win7 laptop well.
Nevertheless, when I followed all of the various driver upgrade methods shown in the Absolute Beginner Guide, plus uninstalling the driver for the device in Device Manager, re-running the STM driver installation program, directing Windows to the new DeFuseDemo driver files, nothing worked. In every case Windows said that the driver was "up to date".
So, finally, my question: is there any reason to persist with trying to get a newer version of the driver to be associated with the nanovna given that the Windows software seems to work OK with the old version? If so, how to do it?
Thank you.
Roger
