There's no Windows 10 driver for that webcam.
Gigaware was a Radio Shack house brand, and Radio Shack went bankrupt several years ago.
I'm using it on my Windows 10 machine and it works fine. The Windows driver auto installed. I listed it as a Vimcro USB 2.0 PC Camera, so that must have been the original mfg that made it for Radio Shack. Plug and Play.
