As it is well known, the extended support of Windows 7 (Service Pack 1) ends on January 14, 2020. Due to the short time that remains, I raise this question.
What consequences could an outdated operating system without continued updates have?
Taking into account that:
Firewall installed, updated and configured the rules for applications that are allowed to connect to the internet. In addition to this and as additional protection, having the file control of the firewall active (it warns against a change in key registry keys, connection to the network, use of the keyboard, etc).
Standard account for daily use. The administrator account, only to make installations and important modifications in the system.
Even if I do not have the system updated and having all of this configured, what problems could it bring me?
