Windows powershell keeps randomly opening for a split second..

Hi, I'm Henry! I will help you with this.

It sounds like something is triggering PowerShell to run periodically in the background. Here are a few possible causes and solutions:

1. Check Task Scheduler

• Some scheduled tasks may be running PowerShell automatically.
• Open Task Scheduler (Windows + S, search for "Task Scheduler").
• Look under Active Tasks for any entries related to PowerShell.
• If you find a suspicious task, disable or delete it or if you don’t recognize any task, just send me a screenshot, I will help check for that.

2. Scan for Malware

• Some malware or unwanted scripts may be executing PowerShell commands.
• Run a full scan using Windows Defender or a trusted antivirus program.

3. Use Process Monitor

• Sysinternals Process Monitor can help track what is launching PowerShell.
• Download it from this link.
• Open and filter for Process Creation events.
• Look for PowerShell-related entries and check their parent process.

4. Check Startup Programs

• Open Task Manager (Ctrl + Shift + Esc) and go to the Startup tab.
• Disable any unknown or unnecessary startup programs.

5. Perform a Clean Boot

• A clean boot helps identify software conflicts.
• Open msconfig (Windows + R, type msconfig).
• Go to the Services tab, check Hide all Microsoft services, then click Disable all.
• Restart your PC and see if the issue persists.

6. Reset PowerShell Execution Policy

• Open PowerShell as Administrator and run: Set-ExecutionPolicy Restricted
• This prevents unauthorized scripts from running.

If the issue continues, let me know, and we can dig deeper.
