Hi nurbles,
Welcome to Microsoft Community.
I'm Hahn and I'm here to help you with your concern.
I'm sorry to hear that you're having trouble with your source control provider on Windows 11 Pro. I understand that you're looking for information about changes to root folder security in Windows 11 Pro that might be causing this issue.
Regarding your question about changes to root folder permissions/protections in Windows 11 Pro, I can confirm that there have been no significant changes made to the default permissions and protections for root folders compared to Windows 10 Pro. However, it is possible that there may be some differences in the way that your source control provider interacts with the operating system on Windows 11 Pro, which could be causing the issue you are experiencing.
Unfortunately, root folder permissions/protections issue is not supported on the Microsoft Answers forum. It is more suitable for publishing on Microsoft Learn (English only), you can click on "Ask a question", there are experts who can provide more professional solutions in that place.
Here is a link: Windows 11 - Microsoft Q&A to the forum where you can raise specific scenarios and share your idea to help solve the problem.
I won't be able to help you, but I'll leave that question open in case one of our amazing volunteers has ideas for you.
Your Sincerely
Hahn - MSFT | Microsoft Community Support Specialist
