Tips
- Back up your scripts and profiles before updating, in case of compatibility issues.
- Use Windows Terminal for a better PowerShell experience and easier management of multiple shells.

Troubleshooting
If your PowerShell update does not go as planned, here are steps to resolve common issues:
- Installation fails or error messages appear: Ensure you are running the installer as an administrator. Right-click the MSI file and select Run as administrator. Check your system for pending Windows updates, as they can interfere with the installation.
- PowerShell version does not update after installation: Close all PowerShell windows, then restart your computer. Sometimes, a system restart is necessary for changes to take effect.
- Old PowerShell versions still launch: Check if multiple versions are installed. Uninstall older versions via Settings > Apps > Installed apps, or use the Control Panel. Ensure the new version is added to your PATH environment variable.
