After January 14, 2020, Microsoft will no longer provide security updates or support for PCs with Windows 7.
Alfa Network Inc. makes a number of products that are Windows 7 compatible. We will continue to make those products available, and continue to advertise Windows 7 compatibility where applicable. But because Windows 7 will not see security updates after January 14th, we would recommend upgrading your operating system to Windows 10 if possible. With few exceptions, most Alfa products are now Windows 10 compatible. See this page here for more details.
