Chrome updated itself automatically
If your PCs/laptops were powered on any time over the last three days (from 5 March onwards) it's highly likely that Chrome has already updated itself.
If you need to check a bunch of them, then use
dir "\\<pcname>\C$\Program Files\Google\Chrome\Application" /ad
on each PC, and look for the folder named 72.0.3626.121
Or perform the equivalent in PowerShell!
