Hello, 

    I want to know how wireguard-go works, and I tried it on Ubuntu and Windows7.

    I can run it on Ubuntu, but get failed on Windows7 as following:

    -----------------------------LOG BEGIN------------------------------------------

    wireguard\wireguard-go.git>go run main_windows.go wg0
    Warning: this is a test program for Windows, mainly used for debugging this Go package. For a real WireGuard for Windows client, the repo you want is <https://git.zx2c4.com/wireguard-windows/>, which includes this code as a module.
    INFO: (wg0) 2019/08/13 16:17:24 Starting wireguard-go version 0.0.20190805
    DEBUG: (wg0) 2019/08/13 16:17:24 Debug log enabled
    ERROR: (wg0) 2019/08/13 16:17:31 Failed to create TUN device: Error registering rings: Access is denied.
    exit status 1

    -----------------------------LOG END--------------------------------------------  

    What's the meaning of "Error registering rings: Access is denied."?

    I'm sure that I run it with administrator role.

    Or any advice?

    Thanks in advance.
