The video discusses enhancing the security of Windows computers using PowerShell through various settings and modifications. Key points include disabling vulnerable versions, setting up Constrained Language mode, and blocking PowerShell scripts. Different strategies are detailed for Windows Pro and Home Edition users to manage policies and prevent script execution. Additionally, steps for securing PowerShell 7 against malware are outlined. While these measures improve security, they are not foolproof. The video content also promotes future videos on computer security topics, such as using AppLocker.

In this segment of the video, the speaker discusses three settings to enhance the security of a Windows computer using PowerShell. The first setting involves disabling the vulnerable older version, PowerShell 2.0. The second step is setting up Constrained Language mode to restrict the types of commands PowerShell can run, preventing malware activities. Lastly, a policy to block PowerShell scripts from running is introduced to further safeguard the system. The speaker emphasizes that these measures do not make the computer impervious to malware but eliminate low-hanging vulnerabilities. The process is explained step-by-step for each setting to improve system security.

In this segment of the video, the speaker talks about modifying system environment variables in Windows to improve security in PowerShell. They guide viewers on how to create a new variable named “PSLockDownPolicy” with a value of four. This modification is aimed at restricting PowerShell capabilities to Constrained Language mode to enhance security.
Furthermore, the video delves into PowerShell script execution policies and explains how they can be easily bypassed. The speaker demonstrates how a simple command can change the execution policy to allow scripts to run, indicating that this default security measure is primarily to prevent accidental script execution. They then mention a method to prevent bypassing the execution policy in Windows Pro Edition by utilizing Group Policy Editor.

In this segment of the video, it is explained that for Windows Home Edition users who do not have Group Policy Editor, they can utilize a free program called Policy Plus to manage policies. The tutorial demonstrates how to navigate to specific settings within Policy Plus to control the execution of PowerShell scripts, including disabling script execution to enhance security. It’s advised to save policies in Policy Plus for Home Edition users. Furthermore, the video highlights the importance of updating to PowerShell 7 separately from Windows PowerShell to ensure security measures are effective.

In this segment of the video, the speaker explains how to set up execution policies for PowerShell 7 to enhance security against malware. The process involves downloading specific files from the GitHub page, copying them to the appropriate directories, and adjusting settings in Group Policy Editor. By configuring the “Turn On Script Execution” setting to Disabled or mirroring Windows PowerShell settings, users can prevent malware from running scripts. The speaker notes that while the setup enhances security, it is not foolproof. Users may need to adjust settings to run scripts and can still use PowerShell commands. Overall, implementing these steps can significantly improve computer security against certain types of attacks.
