What is BIOS and Why Do You Need to Update It?
What is BIOS?
BIOS stands for Basic Input Output System. It is a low-level software that is stored on a chip on your motherboard and controls the hardware and boot process of your computer.
When you turn on your computer, the BIOS performs a series of tests to check if your hardware components are working properly and then loads the operating system from your hard drive or other storage device.
Why Do You Need to Update It?
Updating your BIOS can bring several benefits to your computer, such as:
Fixing bugs or errors that may cause your computer to crash, freeze, or behave unpredictably.
Adding support for new hardware or features that your current BIOS may not recognize or enable, such as a new CPU, GPU, RAM, SSD, etc.
Improving the performance or security of your computer by optimizing the settings or patching the vulnerabilities of your BIOS.
However, updating your BIOS also involves some risks, such as:
Bricking your motherboard if the update process fails or is interrupted by a power outage, a virus, or a user error.
Voiding your warranty if the update is not authorized by the manufacturer or if you use a modified BIOS file.
Causing compatibility issues with your hardware or software if the update is not compatible with your system configuration or operating system.
Therefore, you should only update your BIOS if you have a valid reason and if you are confident that you can do it safely and correctly.
How to Check Your Current BIOS Version?
Before you update your BIOS, you need to check your current BIOS version to see if you need an update or not. You also need to know your BIOS version to find and download the right BIOS update file for your motherboard.
There are several ways to check your BIOS version, such as:
Using the command prompt: Open the command prompt by pressing Windows + R and typing cmd. Then type wmic bios get smbiosbiosversion and press Enter. You will see your BIOS version displayed on the screen.
Using the system information panel: Open the system information panel by pressing Windows + R and typing msinfo32. Then look for the BIOS Version/Date field under the System Summary section. You will see your BIOS version and date displayed on the screen.
Using the BIOS setup menu: Restart your computer and press the appropriate key (usually F2, F10, F12, Del, or Esc) to enter the BIOS setup menu. Then look for the BIOS version information on the main screen or under the System Information tab. You will see your BIOS version and date displayed on the screen.
What is SLIC and Why Do You Need It?
What is SLIC?
SLIC stands for Software Licensing Description Table. It is a special table that is embedded in the BIOS of some computers and contains Windows activation information.
The SLIC table contains a digital signature and a certificate that match the product key of a specific Windows edition. When you install Windows on a computer with SLIC in the BIOS, Windows will automatically activate itself offline using the SLIC information without requiring you to enter a product key or go online for verification.
This method of activation is called OEM activation and it is used by some computer manufacturers (such as Dell, HP, Lenovo, etc.) to pre-install and activate Windows on their computers before selling them to customers.
Why Do You Need It?
The benefits of having SLIC in the BIOS are:
You can install and activate Windows without needing a product key or an internet connection. This can save you time and hassle when you reinstall Windows or upgrade to a new Windows edition.
You can avoid activation errors or problems that may occur due to invalid, expired, blocked, or used product keys. This can save you money and trouble when you buy Windows from unreliable sources or use pirated copies of Windows.
You can enjoy genuine Windows features and updates that are only available for activated Windows users. This can improve your user experience and security when you use Windows.
However, having SLIC in the BIOS also has some drawbacks, such as:
You may not be able to use SLIC activation if you change your motherboard or use a different Windows edition than the one that matches your SLIC information. This may require you to buy a new product key or use another method of activation.
You may not be able to update your BIOS with SLIC if your motherboard manufacturer does not provide updated BIOS files with SLIC information. This may prevent you from enjoying the benefits of updating your BIOS as mentioned above.
You may violate the terms and conditions of Microsoft's software license agreement if you use SLIC activation on a computer that is not authorized by Microsoft or its partners. This may expose you to legal risks or penalties if you are caught by Microsoft's anti-piracy measures.
Therefore, you should only use SLIC activation if you have a legitimate reason and if you are aware of the risks and responsibilities involved. How to Check Your Current SLIC Version?
Before you update your BIOS with SLIC, you need to check your current SLIC version to see if you already have SLIC in your BIOS or not. You also need to know your SLIC version to find and download the right BIOS update file with SLIC for your motherboard.
There are several ways to check your SLIC version, such as:
Using RW-Everything utility: Download and run RW-Everything utility from here. Then click on the ACPI icon and select the SLIC tab. You will see your SLIC version and other information displayed on the screen.
Using SLIC Dump Toolkit: Download and run SLIC Dump Toolkit from here. Then click on the Dump button and select the BIOS option. You will see your SLIC version and other information displayed on the screen.

Which One Do You Need?
The SLIC version you need depends on two factors: your Windows edition and your motherboard compatibility.
You need to choose a SLIC version that matches your Windows edition and supports offline OEM activation for it. For example, if you want to activate Windows 7 offline, you need to use SLIC 2.1 or higher.
You also need to choose a SLIC version that is compatible with your motherboard and its BIOS chip. For example, if your motherboard has a legacy BIOS chip that only supports up to SLIC 2.1, you cannot use SLIC 2.2 or higher.
To determine which SLIC version you need, you can use one of the following methods:
Using the motherboard manual: Check the manual of your motherboard or visit the manufacturer's website to find out which BIOS chip and which SLIC versions are supported by your motherboard.
Using the BIOS modding community: Visit one of the online forums or websites that specialize in BIOS modding and ask for advice from the experts or users who have similar motherboards or BIOS chips as yours.
Using trial and error: Try different BIOS update files with different SLIC versions until you find one that works for your motherboard and your Windows edition.
