How to stop installation of Win10 but install Win8 updates

[after]

I have Windows 8.1. I booked a Windows 10 before its premiere, and on the release he appeared for download in Windows Update. But I changed my mind and I do not want upgrade. But now I can not install the updates to Windows 8.1 because it always starts install Windows 10 even though it unchecked. I canceled my reservation but it did not help. What should I do?
