What the internet will tell you this means?
When you 'Google', IT industry websites will come up top and recommend you upgrade all machines as a matter of urgency.
What this actually means?
Assuming you're already keeping asset and risk registers up to date. Re-assess the risks of continuing to use these operating systems following 14th January, and make sure any additional mitigations needed are in place before then.
