Security updates are meant to patch vulnerabilities that attackers might exploit, so upgrading and staying current is important in order to protect your data and network.
Apart from the security risk, Microsoft also points out that business that fail to keep their software current also run the risk of failing to meet regulatory obligations.
Organizations can also lose independent software vendor (ISV) support as many vendors no longer support older versions of IE, said Microsoft.
