How to See Last BIOS Boot Time in Windows 10
UEFI (Unified Extensible Firmware Interface) is a standard firmware interface for PCs, designed to replace BIOS (basic input/output system). This standard was created by over 140 technology companies as part of the UEFI consortium, including Microsoft. It's designed to improve software interoperability and address limitations of BIOS.
The Task Manager in Windows 10 displays your computer's Last BIOS time in the Startup tab.
The Last BIOS time metric is the amount of time in seconds that the UEFI firmware spends identifying and initializing hardware devices and running a power-on self-test (POST) before it begins booting Windows 10 when you start the computer.

The Last BIOS time time will vary for each computer, but you can often tweak your UEFI firmware settings like below to help lower the time.
- Turn on fast boot feature if available.
- Turn off to display a logo at bootup, or change it's delay time to lower it.
- Change the device boot order to remove any slow device(s) you don't use.
- Disable network boot if not needed.
- Disable power-on self test (POST) processes (ex: memory test) you don't want.
- Disable any hardware controllers or ports (ex: PS/2, FireWire, USB, etc...) that you don't use.
- Upgrading the firmware version may also improve time if the update resolves any hardware issues.
This tutorial will show you how to see the last BIOS time for how many seconds it took your PC's BIOS (UEFI Firmware) to finish initializing at startup before booting Windows 10.
Here's How:
1 Open Task Manager (Ctrl+Shift+Esc) in more details view.
2 Click/tap on the Startup tab in Task Manager. (see screenshot below)
3 Look to see how many seconds it shows for the Last BIOS time towards the top right corner.
If Last BIOS time is blank, it means the motherboard's UEFI firmware didn't provide (ex: not supported) this information for Windows to display.
That's it,
Shawn
