To ensure that Windows 10 remains protected against malware, Microsoft has enabled support for Secure Boot, which works via UEFI. Secure Boot ensures that your PC only uses firmware that the manufacturer trusts at boot time. However, in many cases, you will need to disable Secure Boot on Windows 10 due to incorrect hardware configurations.
If you wonder what the UEFI is, it extends to the unified extensible firmware interface and is the next generation of popular BIOS. It is secure, can store more data, much faster than the BIOS and is almost like a tiny operating system that runs on the PC firmware, and it can store much more than a BIOS. Best part, it can be updated by OEM via Windows Update.
With UEFI, Windows 10 offers security features such as Secure Boot, Windows Defender Device Guard, Windows Defender Credential Guard, Windows Defender Credential Guard and Windows Defender Exploit Guard. You will find below a list of the functions you receive:
- Faster start and restart times.
- It easily supports large hard disks (over 2 terabytes) and disks with more than four partitions.
- Multicast deployment support that allows PC manufacturers to transfer a PC image that can be received by multiple PCs without overloading the network or image server.
- Support for optional UEFI firmware drivers, applications and ROMs.
