Windows 10 re-opens all programs after shutdown / restart?

Hello dear , below  is simpe procedure for fully shut down you pc .

1. Go to control panel.
2. Click on power options.
3. Then click on what the power buttons do.
4. Select change settings that are currently unavailable.
5. Uncheck the the box turn on fast starup.
6. Click on save changes.

no such setting? 

I recently upgraded to an SSD and thought I was going crazy because my PC was taking 7-8 minutes to boot! 

I followed this:

Go to Settings - Accounts - Sign-in 

Go to Privacy and turn this option off 'Use my sign info to automatically finish setting up'

Now my boot time is 4-6 seconds.

Why would there not be a user-friendly off switch for this?

Nope, not even in February 2019 with all updates does this work. Still using shortcuts for a proper shutdown/restart.

please forgive me if this is a repost, but the best way i've found so far is to make shutdown and restart shortcuts:

create new shortcuts on the desktop, then pin them to the taskbar (i have them as icons on winstep nexus ultimate toolbar)

restart: c:\windows\system32\shutdown.exe /r /f /t 0

shutdown: c:\windows\system32\shutdown.exe /s /f /t 0

single click to shutdown or restart the system without restarting all my running programs and without alt-f4-ing everything

This has recently started happening to me and I would add shutting stuff down before hand does not work as I always shut everything down before shutting windows 10 down. It will always open the last thing I viewed in my browser together with other programmes and I only have essentials in the start up programmes. I thought it might be related to my recent disabling of fast start up. I went into shutdown settings ( which is at - Control Panel\All Control Panel Items\Power Options\System Settings) thinking I would go back to fast startup only to find that normal start up is no longer an option.The only settings are

1-turn on fast start up

2-sleep

3-hibernate

4-lock

and sleep and lock are selected but all is greyed out so can't make changes. I suspect if I find a way to re enable fast start up this problem will go away but I disabled fast start up in the first place because it was causing another issue which annoyed me (can't remember what it was). It's as if microsoft are forcing me to use fast start up. I hate these programmes being open when I start up. Shirt I don't even like it when Firefox takes me to my last browse, if I hadn't finished I wouldn't have closed it. I think I must be slightly OCD but anyway, I just find this extremely annoying.

 I think they're inventing and adding stuff to windows 10 just for something to do or maybe to justify their employment.

EDIT- I just remembered why I disabled fast start up in the first place. When I shut down windows would often re start so I turned off fast start up after reading a thread about it. It worked, but now this.

I thought it had something to do with me having windows on an M.2 Drive because i had thought the drive was the reason why i could not flash my bios... because every time i tried flashing my bios (without adequate help from Asus)  my M.2 drive was no longer detected by the MOBO after each attempt, had to clear cmos every time. but anywho i got to finally flash the bios with forums like this.. had to use Brenamer .. but long story short now... I had shut down windows.. unplugged almost everything that i had to to remove the M.2 Drive and flashed the bios successfully...OCed the CPU and put everything back.. restarted and Windows opened up to how it looked before i shut down.. i kinda like the feature.. its like Xbox Instant On almost.
