Shutdown time increases when saving contents to image

Hi.
I have a 2048Mb NTFS RAM disk with the "Save Contents to Image" option enabled. With this option, PC shutdown time increased by 10-18 seconds instead of the usual ~5 seconds. The disk uses only 100Mb in RAM and saves it to SSD. The same happens with exFAT. Is there a reason for such a delay?

This may be due to a Windows feature called 'hybrid boot'. When you shut down a hybrid boot system, this feature saves the current system state to the hard disk before switching off. On boot, it restores the system state back into memory. This process adds a delay on top of saving and loading the RAM Disk image.

We recommend disabling the hybrid boot permanently, which can be done in either of the two ways:

  • Open an elevated command prompt and type
    REG ADD "HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Power" /V HiberbootEnabled /T REG_DWORD /D 0 /F
    Then reboot.
  • Alternatively, if you don't hibernate your PC and want to save a few GBs of disk space, you can disable hibernation. This will permanently deactivate the hybrid boot as well. For that, in an elevated command prompt type
    powercfg /h off
