You've been lucky.
Many people who were using their webcam with W7, found out when they switched to W10 that it no longer worked.
Others even got to see it work, and lost it after some major Update, despite buying it as compatible with the new OS.
Unless things changed in recent months, I know of cases of people who fell for the deals on some Logitech models, and found out the second case I mention.
In my case, an old Microsoft webcam, still works despite everything.
Regards!
