1) Is there a command line parameter that allows me to use the command PowerShell -Command "single-powershell-command" or PowerShell -ExecutionPolicy Bypass -Command "single-powershell-command" from cmd.exe in Windows 10? Currently Windows Defender interpretes both forms of my command malicious and blocks them. 2) What other methods can I use from cmd.exe to prevent this kind of overreaction from Windows Defender? I prefer native methods over modifying policies or Windows Registry or installing something. I can accept turning off Real-time Protection if it is turned on again immediately after the execution of my single PowerShell command and if turning off/on can both be done from cmd.exe.

Yes, there are several native methods available to execute PowerShell commands without triggering Windows Defender. Here are the approaches, ordered by preference:

Use Native CMD.EXE Alternative

SuggestedOPTION 1
cmd /c "your_command_here"

Pros

  • Native Windows functionality
  • No PowerShell involvement
  • Won't trigger PowerShell-specific defenses
  • Simplest approach

Cons

  • Limited to basic commands
  • May not support complex operations

Instead of using PowerShell, use CMD.EXE directly

superuser.com
. This bypasses PowerShell-related security checks entirely while remaining within native Windows tools.

Temporarily Disable Real-time Protection

OPTION 2
1
2
3
sc stop WinDefend
PowerShell -Command "your_command_here"
sc start WinDefend

Pros

  • Maintains system security after execution
  • Allows any PowerShell command
  • Uses native Windows service control

Cons

  • Brief window without protection
  • Requires admin privileges

This method temporarily stops Windows Defender during command execution

superuser.com
. The service is restarted immediately after, maintaining system security while allowing PowerShell commands to execute without interference.

Modify Command Structure

OPTION 3
powershell.exe -NoLogo -NonInteractive -WindowStyle Hidden -Command "& {your_command_here}"

Pros

  • Maintains PowerShell functionality
  • Minimizes visible impact
  • Doesn't require service manipulation

Cons

  • May still trigger some protections
  • Less reliable than other methods

This approach modifies how PowerShell executes the command

viperone.gitbook.io
. While less reliable than other methods, it provides an alternative without requiring system modifications.

Let's visualize the decision flow for choosing the best method:

Yes

No

Yes

No

Need to run
PowerShell command

Can use basic
CMD command?

Use CMD.EXE:
cmd /c 'command'

Need admin
privileges?

Temporarily disable Defender:
sc stop WinDefend
Run command
sc start WinDefend

Modify command structure:
powershell.exe -NoLogo ...
with hidden window

Thoughts
Looking at the diagram, I notice: 1. The flow is clear and logical 2. The code examples are included inline 3. The decision points are well-labeled 4. The color coding helps distinguish between decisions and actions 5. However, I should add a brief explanation of how to read the diagram to ensure users understand the decision-making process Let me add a short explanation to make the diagram more actionable.

The diagram above shows the recommended decision flow:

Important Security Note
These solutions are provided for legitimate administrative purposes. Always maintain proper security practices and consider using alternative antivirus solutions if frequent PowerShell usage is necessary for your workflow.
