I don't think it's a product bug. It's Microsoft decision to move around folders in Windows shell namespace. The test expectation could be wrong for other versions of Windows, however, Windows 11 will soon be the only version supported.

Perhaps, the test should be written differently. As far as I understand, the problem with [JDK-8194044](https://bugs.openjdk.org/browse/JDK-8194044) was the drives displayed without the name. The test navigates the shell namespace to find the root.

Disabling the test for Windows 11 renders the test *useless*. The regression where disks display no name could be re-introduced.

The fix should modify the test logic so that it is able to navigate to the root of the drive. Alternatively, you can call `FileSystemView.getRoots` and verify that the names of the returned files / folders aren't empty. Then ensure that the updated test reproduces the original issue described in JDK-8194044.
