    Excuse me but OS bug because

    You cannot conclude that. It's possible, for example, that SetVolumeMountPoint is looking up other information that's been registered for your device, and part of that isn't right. You just don't know until you single step through the code. Microsoft just doesn't make announcements about implementation.

    Then How do i do ?

    The function SetVolumeMountPointW contains several checks which will result in SetLastError(ERROR_INVALID_PARAMETER). For example:

    • if GetDriveTypeW(lpszVolumeMountPoint) is not DRIVE_FIXED
    • if IsThisAVolumeName(lpszVolumeName, ) says no

    Run the same checks that SetVolumeMountPointW runs on the input parameters to figure out which check fails. Just disassemble SetVolumeMountPointW of kernel32.dll.
