Hi 婵 苏,
The necessity to shut down your computer twice is typically caused by a power state transition failure where Windows struggles to communicate with your motherboard's advanced configuration interface. Even though you disabled Fast Startup, Windows might still be holding onto a corrupted hibernation file that interrupts the shutdown sequence. You can completely purge this file by opening an elevated Command Prompt as an administrator and running powercfg.exe /hibernate off. This deletes the hidden session data and forces Windows to rebuild its power state configuration from scratch on the next boot.
Another common cause for this behavior is a registry setting that forces the system to securely wipe the virtual memory paging file during every shutdown. This scrubbing process takes an extensive amount of time, often making the system appear frozen and prompting users to force a secondary shutdown. To resolve this, open your Registry Editor and navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management. If the ClearPageFileAtShutdown value is set to 1, change it to 0 to allow the shutdown sequence to complete normally.
The physical hardware power controls also rely heavily on your motherboard's chipset drivers to receive the correct signals from the operating system. If the Intel Management Engine Interface or your AMD equivalent is outdated or corrupted, Windows will send the shutdown command but the motherboard will never physically cut the power. You can locate this component under System Devices in your Device Manager, but you will need to visit your motherboard manufacturer's official support page to download and install the latest versions for your specific board.
