MICROSOFT HAS ACTIVATED the flashing red light in the hand of yet another product that has reached maturity.
Office 2010 will be declared ‘end-of-life’ a year hence, on the 13th October 2020, a decade and three months after it first launched following development under the name Office 14 (fun fact: there was no version 13 for superstitious reasons) and five years after mainstream support ended.
After this date, the usual end-of-life rules will apply – the products will not receive security patches and will, therefore, put your entire Windows system at risk. They should be migrated and the 2010 versions removed from machines.
