There is a bug with Windows 10 and Windows Server 2019. When the advanced security settings of a folder are enabled to deny appending data, deleting files, and deleting folders, the first attempt to copy a file fails, but the second attempt is successful. The problem reoccurs after restarting the computer, while on Windows Server 2008 R2, it functions normally.

When using the options shown in the attached image, copying a file to the folder prompts a duplication message and creates a file with a size of 0kb. However, a second file can be successfully copied. After restarting the system, the first file can't be copied again.

The same settings work fine on Windows Server 2008 R2.

Of course, unticking the box to deny (creating folder/appending data) allows successful copying, but I need this configuration.

The issue can be reproduced on both Windows 10 and Windows Server 2019.

I would appreciate if you could help me understand the reason for this. Thank you.
