I know this has been asked before but the answers given have not worked.
1. Edit the registery.
2. Disable fast startup.
I have an Acer Aspire V17 Nitro Black (VN7-791G) with Windows 8.1. I want Num Lock on always. When I boot the machine in the morning it is off. When I wake the machine after a period of inactivity it is off. I have edited the registry under the keyboard settings per other replys in these forums with no change. I have disabled fast startup per replys in these forums again with no change. I contacted Microsux because I think it is a windows issue but they said to contact Acer. Acer chat is of no use they want you to pay them to modify the registry. So here I and I believe others are stuck with a machine that does its own thing.
