Fixed

• "Cancel" option bug:
  Selecting option [0] Cancel in Windows Update and DNS menus now correctly returns to the main menu, instead of running code from other options.

• Robust menu logic:
  Invalid or blank user input in option menus now triggers a clear error message and re-prompts, instead of exiting or falling through.

• Whitespace trimming:
  User input is now stripped of leading/trailing spaces before comparison, preventing accidental menu errors.

Removed/Deprecated

• WMIC dependency eliminated:
  All code relying on wmic for detecting active network adapters (e.g.
  wmic nic where "NetEnabled=true" get NetConnectionID ^| findstr /R /V "^$"
  ) has been removed.

Added/Improved

• PowerShell-based adapter detection:
  Active network adapters are now detected with a PowerShell command:
  powershell -Command "Get-NetAdapter | Where-Object { $_.Status -eq 'Up' } | Select-Object -ExpandProperty Name"
  ensuring compatibility with all modern Windows 10/11 versions.

• Better error handling:
  If no active network adapters are found, user is informed and returned to the menu.

• Maintained language independence:
  Detection of network adapters now works regardless of Windows language settings.

Summary

• Menu choices behave as intended and cannot fall through to incorrect actions.
• Adapter detection is future-proof and works everywhere PowerShell is available.
• Input handling is user-friendly and robust against typos and blank inputs.
• All WMIC reliance is gone – script will not break on newer Windows installations.
