How to Fix Execution Policy Error in PowerShell Quickly

The PowerShell execution policy error happens because scripts are blocked by default for security. Fix it by running Set-ExecutionPolicy RemoteSigned -Scope CurrentUser in an elevated PowerShell window to allow local scripts to run safely.

Why This Happens

PowerShell has a security feature called ExecutionPolicy that controls which scripts can run. By default, it is set to Restricted, which blocks all scripts. This causes an error when you try to run any script.

powershell

powershell
# Trying to run a script
./myscript.ps1

Output

File C:\path\to\myscript.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.

The Fix

Change the execution policy to RemoteSigned which allows running local scripts and requires downloaded scripts to be signed. Run PowerShell as Administrator and enter the command below.

powershell

powershell
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser -Force
# Then run your script again
./myscript.ps1

Output

Execution Policy Change
The execution policy helps protect you from scripts that you do not trust.

Scope ExecutionPolicy
----- ---------------
CurrentUser RemoteSigned

# Output of script runs normally without error

Prevention

To avoid this error in the future, always check your execution policy before running scripts. Use Get-ExecutionPolicy -List to see policies for all scopes. Set the policy only for the needed scope (like CurrentUser) to keep security tight. Avoid setting Unrestricted unless absolutely necessary.

powershell

powershell
Get-ExecutionPolicy -List

Output

        Scope ExecutionPolicy
        ----- ---------------
MachinePolicy       Undefined
   UserPolicy       Undefined
      Process       Undefined
  CurrentUser       RemoteSigned
 LocalMachine       Restricted

Related Errors

Other common errors include:

• "Script is blocked by group policy": This means a system admin set policies that override your settings. Contact your admin.
• "Cannot load script because it is not digitally signed": Happens if policy requires signed scripts. You can sign scripts or change policy to RemoteSigned.

Key Takeaways

PowerShell blocks scripts by default for security with the execution policy.

Run 'Set-ExecutionPolicy RemoteSigned -Scope CurrentUser' in admin mode to fix the error safely.

Check current policies with 'Get-ExecutionPolicy -List' before changing settings.

Avoid setting execution policy to Unrestricted to keep your system safe.

If blocked by group policy, contact your system administrator for help.
