However, as mentioned by Al Hill, your adapter was never supported in Windows® 10. This means that your best hope will be to simply allow your operating system to install it's (generic) inbox drivers.
The problem here will be that in some cases, updating to a newer OS build may further widen the compatibility gap and your adapter may stop working in the future. Also we cannot guarantee full functionality/performance.
