Windows 10: What is “Fast” Startup doing?

Ive recently (3 Oct 20) completed the Win7 > Win10 migration (whilst the jurys still out on whether I consider it an upgrade Ill confess its going much better than feared) and am familiarizing myself with the changed environment. One thing thats puzzling me is Fast Startup. Given the lack of consensus found on the net regarding the value of Fast Startup I ran some tests to satisfy my curiosity. My methodology was to (a) turn off AV, (b) shutdown from cmd window (shutdown /s /f /t 0) and (c) run vbs script with different scenarios:



The second Fast Startup UNchecked is because I was so startled at the first run having the same reboot time as Fast Startup checked. Apparently the most charitable thing that can be said based on these observations about the impact of Fast Startup on boot/reboot times is that its negligible at best.

What is Fast Startup doing since it doesnt actually seem to have anything to do with starting up? Is it integral to some other function (?sleep, maybe?) or is it marketing trivia I can safely ignore?

Can't get GPU-Z to start with Windows 8.1 startup

I'm not sure how to do that. Could you list the steps for a noob?

 

Turn off Fast Startup

Hi Michel,

Please take note that you must be signed in as an Administrator to be able to turn fast startup on or off. Fast startup requires that
hibernate be enabled. If you disable hibernate, then it will also disable fast startup.

Steps on how to manually turn off the Fast Startup

• Open the Control Panel (icons view), and click on the
  Power Options icon.
• Click/tap on the Choose what the power buttons do link on the left side
• Click/tap on the Change settings that are currently unavailable link at the top
• If prompted by UAC, click/tap on Yes

If the option for turning off the Fast Startup is not available, then changing the registry key maybe required.

Note: Please note that configuring Registry key requires extra care as it might cause another issue with your system.

• Type RegEdit in the search field on your Task bar
  and open the Registry tool.On the left pane of the Registry window, locate
  HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Power.
• On the right pane of the said location, check if the HiberbootEnabled
  is available. If not, we need to create it by clicking the right key of the mouse, select New
  and click on DWORD (32 bit) Value.
• Replace it with the word HiberbootEnabled under Name
  column.Data value must be zero (0) that will represent as the Fast Startup is turned off.
• Restart the computer for the changes to take effect.

Steps on how to disable UAC in Windows 10

• Type UAC in the search field on your Task bar. (If the search field isn't visible, right-click the
  Start button and choose Search.)
• Click Change User Account Control settings in the search results.
• To turn UAC off, drag the slider down to Never notify and click
  OK.
• You may be prompted to confirm your selection or enter an administrator password.
• Reboot your computer for the changes to take effect.

We look forward to your response.
