hello everyone 
at home I have a personal computer and was out windows icons get 10 and I signed up and checked my computer and the answer is consistent and when I subscribe to Windows 10, it was email registration confirmation but now my computer no longer see the icon on the windows update again and nor do any walking anymore though still not see this icon appear again when the computer updates I can upgrade to windows 10 was not expecting anyone to help ease fears that icon appear on my computer. Thank you very much.My computer is currently using version 8.1 Pro 64bit windows.

If you don't see the icon then there is nothing to get worried.
