I do not put my computer into standby.

Only used (created on shutdown) if you enabled Hibernate mode in
Windows. Do you ever hibernate the OS?

Hibernate is NOT a standby (low-power power-ON) mode. Hibernate is a
power-OFF mode: memory gets copied into a file and the computer is
powered down. On power up and OS boot, the file (hiberfil.sys) gets
read back into memory to restart where you left off before. Takes time
to write all of memory into a file, so shutdown takes longer, and also
takes time to read the file into memory on Windows startup (although the
assumption is that takes much less time then loading everything from
scratch).
