Petty annoyance wish...
Can we cut back on the compulsive 'no other programs can be running' of the AC updaters? There is no reason for it. (Tip: Once the installation starts, go ahead and relaunch anything except AC & PM. Some requirement!) You can patch the operating system without quitting anything.
On the 1410 patch, it never asked for a password, yet still required a restart. Fundamentally nonsensical.
