time-limited windows logon sessions

[NorthboundOcclusive]

here's an interesting puzzler-

situation: family PC (windows 10) with several childrens, whom spend way too much time on the computer. mom wants a good way of enforcing time limits for the kids.

to my thinking there's two ideal ways of tacking this problem-

1) free/commercial software to be able to schedule per-user time frames and logs user off afterwards (say, after 30, 60, 90minutes)

• i guess the simplest option would be set up a scheduled task that runs on user logon, for something like

  %windir%\system32\shutdown.exe -s -t 7200 -f

  , though logging on again would grant another interval

• found a program called TimesUpKidz, which looks to do what's needed

• figure public libraries must have something to enforce a session duration for users

• microsoft family safety also looks to provide similar functionality, on a per-day basis

2)run a cmd on a voice command, like "Bed Time!" forces user to be logged off.

• since the pc is running windows 10, could Cortana be hooked into to either shutdown/logoff on demand, or run a command (shutdown.exe again) with a given phrase? some other voice recognition software that'll do the trick?
