SOLUTION - I read through all the responses and did some looking and found one that works. It was on HowToGeek and as I was reading through all their steps of the 2-step process there was something in the second step that when I read it I thought, "That has to be answer and not all this other junk." I know, get to the answer already.
OK, so here is what you do.
Step 1 - Boot your machine.
Step 2 - At the logon screen hit your Numlk key.
Step 3 - Restrart the computer without logging in. (They stated shutting down and then booting up but restarting will work)
Step 4 - Logon to your computer and your Numbers Lock should now be on.
PLEASE NOTE - I did not do any of the registry hacks. I am running on Acer Predator 17. I do have a clean install of Windows 10 x64 and I have installed from Acer the Predator Sense, Quick Access, and Others Intel downloads from the Acer website.
Had the same problems as everyone else. The registry tricks and lockscreen work, but only until the computer enters sleep mode.
I can confirm that disabling Quick Access will fix the problem, but at the expense of some of the FN keys not working (airplane mode for example).
Hopefully if somebody from Acer is happening to be reading these threads, the problem could be fixed
REGARDING SLEEP PLEASE NOTE - I do not use sleep mode on my computer. I go into power plan settings and switch it all to Hibernate. You do not want your battery being drained, especially to empty. This is bad on the battery and will wear it out faster. You want to keep your battery at a full charge. I know it has gone back and forth about whether you should let your battery drain or not but batteries only have so many charge cycles. You do not want to let battery to get hot as that is bad for it. Here is an article on debunking the myths. http://www.howtogeek.com/169669/debunking-battery-life-myths-for-mobile-phones-tablets-and-laptops/
Hibernate creates a whole bunch of unnecessary writes to a SSD drive - which will make the drive wear out faster.
It's a toss up which is worse, killing your ssd or battery, but I'll stick with sleep (which btw I never use for an extended period of time)
