PowerShell tool fails with exit code 1 on Windows when pwsh installed via winget

Description

The PowerShell tool (pwsh) fails with Exit code 1 on Windows, even when PowerShell 7 is correctly installed via winget. The Bash tool calling pwsh -Command "..." works fine, so the issue is specific to how Claude Code's PowerShell tool invokes pwsh.

Steps to reproduce

1. Install PowerShell 7 via winget: winget install Microsoft.PowerShell
2. Open Claude Code on Windows
3. Ask Claude to run any PowerShell command using the PowerShell tool

Expected behavior

PowerShell tool executes the command and returns output.

Actual behavior

Exit code 1

No output, no error message.

Environment

• OS: Windows 11 Enterprise 10.0.26100
• PowerShell version: 7.6.1.0 (installed via winget install Microsoft.PowerShell)
• Claude Code version 2.1.126
• pwsh location: C:\Users\<user>\AppData\Local\Microsoft\WindowsApps\pwsh.exe
• Bash tool calling pwsh -Command "Write-Output test" works correctly

Workaround

Using the Bash tool with pwsh -Command "..." works as a workaround.
