On my 64-bit Win8.1 PC, I can't set the "Automatically Start System Explorer After Login" option differently on my admin and standard accounts. Changing the option on one account changes the same option on the other account. I have the "Use One Setting For All Users" option disabled on both accounts. I installed System Explorer v5.7.0, and this PC had no previous versions of System Explorer.
