PowerShell is a powerful command-line tool that enables users to automate tasks in Windows operating systems. In its default configuration, PowerShell execution policies are designed to protect the system by preventing the execution of potentially harmful scripts. While these policies help secure the system, they can also limit the capabilities of PowerShell. Fortunately, there are ways to bypass these execution policies, giving you full access to PowerShell's features.

In this article, we'll explore how to bypass PowerShell execution policies using easy-to-follow code samples. We'll also discuss some of the potential risks involved in bypassing execution policies and how to mitigate them. Whether you're a system administrator or a power user, this article will help you unleash the full potential of PowerShell and take your automation to the next level. So, let's get started!

Understanding Execution Policies

In order to fully comprehend how to bypass execution policies with PowerShell, it's important to first understand what execution policies are and why they exist. Execution policies are security measures put in place to prevent the execution of malicious scripts or commands that could harm a computer or network. They dictate which PowerShell scripts and commands are allowed to run and which are not.

There are six different execution policies that can be set in PowerShell: Restricted, AllSigned, RemoteSigned, Unrestricted, Bypass, and Undefined. Restricted is the default execution policy and prevents any script from running. AllSigned only allows signed scripts to run. RemoteSigned allows signed remote scripts and local scripts to run. Unrestricted allows any script to run without any digital signature requirements. Bypass allows any script to run, but requires a confirmation from the user. Undefined means that no execution policy has been set.

Understanding these different execution policies is crucial for identifying the vulnerabilities and potential areas for exploitation. Once you are familiar with the existing policies, you can then utilize certain techniques to bypass them and execute scripts or commands that would normally be blocked. With the right knowledge and tools, you can unleash the full potential of PowerShell and become a true power user.

Why Bypass Execution Policies?

When working with PowerShell, it's not uncommon to encounter execution policies that limit the commands you can use. These policies are designed to prevent malicious code from being executed on your system, but they can also be a hindrance to legitimate tasks. This is where bypassing execution policies comes in handy. By learning how to bypass these policies, you can unleash the full potential of PowerShell and have more control over your system.

Bypassing execution policies can be useful for a variety of tasks, such as running unsigned scripts, running remote scripts, or automating tasks. For example, if you need to run a script on multiple computers in a domain, you may need to bypass execution policies to get the job done efficiently. While it's true that bypassing execution policies can be risky, it's possible to take appropriate precautions to mitigate these risks.

There are different methods to bypass execution policies, but some of them require administrative rights or may be disabled on your system. PowerShell's -ExecutionPolicy parameter allows you to bypass the execution policy for a single command or session, but it may not be enough for some tasks. This is where more advanced techniques, such as using encoded commands or creating a custom PowerShell profile, can come in handy.

Ultimately, bypassing execution policies should be done with caution and only when necessary. It's important to understand the risks and have a clear understanding of what you're trying to achieve. By learning how to bypass execution policies, you can unlock the full power of PowerShell and accomplish tasks that would otherwise be impossible.

Code Sample 1: Disabling Execution Policy for Current Session

PowerShell is designed to have security mechanisms to protect systems from malicious scripts. One of the security features is the execution policy, which prevents the execution of unsigned and untrusted scripts. However, this can sometimes prevent well-intentioned scripts from running, causing frustration for administrators and developers. Fortunately, PowerShell allows you to temporarily bypass the execution policy for the current session, making it possible to run the scripts you need.

To do this, you can use the Set-ExecutionPolicy cmdlet with the option of RemoteSigned, which allows PowerShell scripts to run, as long as they are signed by a trusted publisher. Here is an example of a code sample that disables execution policy for the current session:

Set-ExecutionPolicy RemoteSigned -Scope CurrentUser -Force

In this code, Set-ExecutionPolicy is the cmdlet used to change the execution policy of PowerShell. "RemoteSigned" is the option used to set the policy to allow scripts signed by a trusted publisher. "-Scope CurrentUser" sets the execution policy for the current user's profile, and "-Force" is used to force the script to set the execution policy without prompting for confirmation.

Overall, this code sample can be useful in situations where you need to run a quick script without having to worry about the execution policy getting in the way. However, it is important to note that temporarily bypassing the execution policy can be a security risk, so it should be used with caution and only for trusted scripts. Once you are done with the script, it is recommended to reset the execution policy to its original value.

Code Sample 2: Creating a Scheduled Task to Bypass Execution Policy

Another way to bypass the execution policy in PowerShell is by creating a scheduled task. This method is particularly useful when you need to run a script on a regular basis, as the scheduled task can be set to run at specific intervals without requiring manual intervention.

To create a scheduled task in PowerShell, you can use the New-ScheduledTaskTrigger and Register-ScheduledTask cmdlets. Here's an example of how you can create a scheduled task to bypass the execution policy:

# Define the trigger for the scheduled task (runs every day at 6pm)
$trigger = New-ScheduledTaskTrigger -Daily -At 6pm

# Define the action to run when the task is triggered (runs PowerShell with the -ExecutionPolicy Bypass option)
$action = New-ScheduledTaskAction -Execute "powershell.exe" -Argument "-ExecutionPolicy Bypass -File C:\Scripts\MyScript.ps1"

# Define the settings for the scheduled task
$settings = New-ScheduledTaskSettingsSet -AllowStartIfOnBatteries -DontStopIfGoingOnBatteries -DontStopOnIdleEnd

# Register the scheduled task
Register-ScheduledTask -TaskName "MyScript Task" -Trigger $trigger -Action $action -Settings $settings

In this example, a task named "MyScript Task" is created to run the script located at "C:\Scripts\MyScript.ps1" every day at 6pm. The task is set to run even if the computer is on batteries and is not stopped when the computer goes into an idle state.

By using a scheduled task, you can ensure that your PowerShell script is run at regular intervals without having to manually bypass the execution policy each time. However, it's important to note that this method can potentially pose security risks if not implemented properly, as any user with access to the task scheduler can potentially modify or execute the script. Therefore, it's crucial to ensure that only authorized users have access to the scheduled task and the script it runs.

Code Sample 3: Using Base64 Encoding to Bypass Execution Policy

Base64 encoding is a technique that translates binary data into a format that can be easily transmitted over the internet or other networks. It can also be used to bypass PowerShell execution policies by encoding PowerShell commands within a Base64-encoded string. This allows PowerShell to execute code that would otherwise be blocked by the execution policy.

To use Base64 encoding to bypass execution policy, you can use the following code:

$command = 'Get-Process'
$encodedCommand = [Convert]::ToBase64String([Text.Encoding]::Unicode.GetBytes($command))
powershell.exe -encodedCommand $encodedCommand

In this example, we first define the PowerShell command we want to execute (Get-Process) and store it in the $command variable. We then use the Convert.ToBase64String method to convert the binary data of the $command variable into a Base64-encoded string and store it in the $encodedCommand variable.

Finally, we use the powershell.exe executable with the -encodedCommand flag to execute the encoded PowerShell command. Since the command is encoded, it can bypass the execution policy and execute without being blocked.

It's important to note that using Base64 encoding to bypass execution policy can be a security risk if the encoded command is malicious. Therefore, it's recommended to only use this technique in controlled environments and with trusted code.

Code Sample 4: Modifying Execution Policy via Registry

Another way to bypass PowerShell Execution Policy is by making changes to the Windows registry. This method involves setting the appropriate values for the ExecutionPolicy key. The ExecutionPolicy key can be found under the following registry path:


The registry key is a string that holds the Execution Policy value. To modify the Execution Policy value, you can use the following code:

Set-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell" -Name "ExecutionPolicy" -Value "Bypass" -Force

In this example, the Execution Policy value is set to Bypass, which allows PowerShell scripts to be executed without any restrictions.

It's worth noting that modifying the Windows registry can have a significant impact on the stability of the system. So, it's essential to ensure that you have the necessary permissions before attempting any changes. It's always best to use caution when making changes to the registry and to thoroughly test the impact of any modifications before deploying them on production systems.

In summary, using the Windows registry to modify Execution Policy is an effective way to bypass PowerShell restrictions without altering Execution Policy settings directly. It provides a viable alternative for users who require additional flexibility and control in their PowerShell environment. However, it's important to use caution when making changes to the registry and to ensure that you have appropriate permissions before proceeding.
