The version information of the Windows 11 I am using is as follows: Microsoft Windows [Version 10.0.22621.1848]. In this system, I was able to solve the problem without using any additional programs. This link was helpful. However, some of the code in the link wraps to the second line, causing an error in the execution of the code. I suggest combining the overflowing code into a single line. I have compiled the following code for you. After launching Windows PowerShell with admin privileges, if you run the code line by line, the desired option, "Never Combine," will be implemented.
Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope LocalMachine -Force
