No. Reboot is always reboot, Windows would be completely useless without >>>> that. "FastBoot" aka fast startup happens when shutting down if not

Actually Fast Starup is a full hibernate (all memory copied into the
hyberfil.sys file).

Source? For example here:
https://learn.microsoft.com/en-us/windows-hardware/test/weg/delivering-a-great-startup-and-shutdown-experience
"Starting with Windows 8.x, the default shutdown and restart scenario
has been updated and named fast startup. Fast startup begins with the
shutdown process and includes writing data to disk similar to the
hibernate process. A key difference is that all user sessions (Session
1) are logged off and the remaining information is written to the
hiberfile."

When user sessions are logged off, all user apps die and so aren't
written to the hiberfil.sys, which, as I stated, makes this "fast
startup" fairly useless.

If you think hiberfil.sys is useless, why not disable it? Use this
command as an administrator:

powercfg.exe /hibernate off.

Restart the machine and see if it makes any difference.

Personally, I find fast startup useful on an old machine, but some
people prefer to start afresh while they make a cup of coffee!

Absolutely nothing uses Fast Startup in the room here.

If my machine had ECC, I would not mind trying it.

For non-ECC machines, the lowest risk option is normal boot procedures.

On my old machines, they go slow, as expected.
