Some days you couldn't make this up.
We already have two practices calling this morning with unauthorized W10 upgrades, looking for us to roll them back/upgrade them to W7.
One of them now has a broken Ethernet connection, Quickbooks is broken, and no one can reach AC because it is broken. Good news it happens to be a practice that is within driving distance of one of us.
Micro$oft the gift that keeps on giving. /snark
