slui 4 not working

SLUI is short for Software Licensing User Interface. It is a command-line utility. SLUI 4 not working is one of the most common issues users run into. SLUI has four commands to activate Windows. Each command uses a different approach for the Activation. Some users misunderstood slui.exe as a virus, which is not the case. It is a windows system file that is important for your computer to work genuinely.

Understanding SLUI

slui.exe is the executable file found in “C:\Windows\System32” that runs the SLUI utility. Administrator privilege is required for this utility to function. It is a command-line tool that later opens a Graphical User Interface (GUI), prompting user input. It takes four integers as input arguments (1, 2, 3,4). Each argument is used for a different purpose and approach to Software Licensing.

SLUI 1

If you run ” slui 1” in the command line as an Administrator, Then Graphical User Interface windows open, showing the Windows Activation Status for the current installation.

NOTE – Your activation status might differ depending on how you installed or activated Windows.

SLUI 2

Suppose you did not activate your windows during the installation process. If you have a product key but do not have Windows Activated, you are then running the SLUI with two as the input integer argument allows you to Activate the Windows using your Product key. Run ” slui 2″ in the command prompt with Administrator privilege, and you would be prompted directly to the activation window and would be asked to enter the product key. Enter the product key and click on Next, it would take 5-6 seconds for verification, and your windows would be activated.

SLUI 3

If you have an already Activated window, but for some reason, you may want to change the product key of your current installation, then use the SLUI 3 command. This command replaces the previous product key with the new one. Open command prompt as an Admin and type “slui 3,” then hit Enter.

SLUI 4 not working

As we have seen, SLUI 4 is different than other Sluis. Therefore users can experience trouble or issues while using SLUI 4. Sometimes slui.exe might not work correctly. When slui.exe does nothing, users can’t activate windows by phone. There could be many possible reasons for it not working, such as Poor internet connectivity, corruption of essential system files, User not having enough rights to operate, etc.

SLUI has been around for a long time in Microsoft’s family of Operating Systems. From windows 7 to windows 11 now and even on Windows Server 2016, the utility is still used to activate the Operating System.
