# PowerShell 2025 Breaking Changes & Migrations

Critical changes, deprecations, and migration paths for PowerShell in 2025.

## PowerShell 2.0 Removal (August-September 2025)

### What's Removed

PowerShell 2.0 has been **completely removed** from:
- **Windows 11 version 24H2** (August 2025)
- **Windows Server 2025** (September 2025)

**Why:** Security improvements, reduced attack surface, legacy code cleanup

### Migration Path

```powershell
# Check if PowerShell 2.0 is installed
Get-WindowsOptionalFeature -Online -FeatureName MicrosoftWindowsPowerShellV2Root

# If you still need PowerShell 2.0 (NOT RECOMMENDED)
# - Use older Windows versions
# - Use Windows containers with older base images
# - Upgrade scripts to PowerShell 5.1 or 7+

# Recommended: Migrate to PowerShell 7.5+
winget install Microsoft.PowerShell
```

**Action Required:** Audit all scripts and remove `-Version 2.0` parameters from any PowerShell invocations.
