In today’s Ask the Admin, I’ll show explain what fast startup is in Windows 10 and how to disable it.
Fast startup was introduced in Windows 8 and uses session 0 hibernation to save the kernel state to disk. Reading the kernel state from disk is 30 to 70 percent faster than a full system initialization on most systems.
While fast startup should be beneficial in most cases, especially in combination with UEFI, it can also be problematic. For example, I’ve come across systems that refuse to connect to wireless networks without a cold boot, assumedly due to a problem with the reinitialized driver. But if an updated driver doesn’t solve the problem, you might want to disable fast startup.
It’s worth noting that while fast startup is enabled by default in Windows 10, hibernation must also be turned on for the option to appear in the control panel. Secondly, fast startup doesn’t apply to system restarts.
Perform the following steps to disable fast startup.
If you want to force a full shutdown from the command line, open a command prompt and use the shutdown command as shown below:
Users can also initiate a full shutdown by holding SHIFT while choosing Shut down from the Power options on the Start menu.
