How to initiate a Full Reboot/Shutdown on Windows 10 Fall Creators Update
Solution 1:
Open Cortana settings and disable the option Pick up where I left off
Now the programs should no longer open again.
If this doesn't help, open Group Policy Editor (gpedit.msc) go to
Computer Configuration -> Policies -> Administrative Templates -> Windows Components -> Windows Logon Option
Set the Policy Name: Sign-in last interactive user automatically after a system-initiated restart to Disabled.
