Hey everyone!
I've developed a simple code to help fix compatibility issues with Windows 11, making it easier for RAN Online to run the latest OS. Also, added compatibility program up to latest Windows Server 2025. Since I know many of you face similar frustrations, I’m making this code available for free! You just need to merge it or replace the whole GetWinVer cpp and h files.
For the context, we met Juver long time ago. And he told me that most ran private server can't even fixed the windows 10 compatibility in ran source. So I did the fixing of GetWinVer code to make it compatible even the incoming windows 11. And as we know, Windows 10 will stop the free updates after October 14, 2025.

Feel free to download, use, and share it with others. I believe in keeping Ran Community great again, and this is my way of contributing to the community. But please don't remove my credits :)
