Microsoft Edge, the default browser Windows 10, currently doesn't allow extensions like the iGive Button. Microsoft is beta testing a new version of Windows 10, the "Anniversary Edition", that includes a version of Edge that supports extensions. That version is supposed to be available to Windows 10 users shortly.
We are in the process of testing the iGive Button for Edge. We expect to release it soon after Microsoft make Edge compatible.
As soon as we are certain that it is working properly, we'll make it available in the Windows App Store
