support expired, But Why Old exe not working?

my Micro box support expired on 9-1-16, Its ok that i wont be able to use new
updates after this date.
But as it is mentioned on micro box support that after expiry ,one should be able to use old exe,

”If you not active this Support, you will still can use all software’s and unlock all the models supported until your end of support.”
