In examining upgrades for the Google Chrome web browser, we see a
different pattern. It reflects a regular cadence of upgrades, as well as
a strong opt-out policy that makes it difficult for users to ignore
update notifications. As seen in Figure 42
, endpoints running the newest version stay relatively steady over the course of many weeks.
Chrome data shows that users recover relatively quickly. In the case of
regular updates, one week is roughly the recovery timeline. In one span
of 9 weeks running through Q2 and Q3 of 2016, however, there were seven
updates. During this time the population recovered, but upgrade fatigue
began to set in. The percentage of users staying with an older version
steadily climbs despite the majority of the population recovering.
