Off Topic: Windows

[Tripple_Delta]

This question shouldn't be here I guess

I was able to setup OPNsense IPsec VPN, connected with OSX, IOS, CentOS and Mint Linux. Had to do a little research though.  :)

But when I try to connect from a Windows system I'm getting nowhere. Why is it always so complicated with Windows?

Anyone with a good suggetion?
