Windows Maintenance Tool – Release Summary

Developer Options / Test Tools

• New Developer Options (40) submenu:
  • Toggle Dry Run (simulate actions, no changes).
  • Toggle Dev Mode (extra diagnostics / testing).
  • Turn both off again from the same menu.
• When enabled, Dry Run and Dev Mode each show a yellow banner in the main menu.

Driver Maintenance

• Old Driver Cleanup (20 → 7):
  • Requires admin; otherwise exits with a clear message.
  • Mandatory driver backup to a DriverBackup_* folder on the Desktop
    (reuses latest valid backup or creates a new timestamped one).
  • Shows keep/delete analysis, asks for global confirmation and per-driver Y/N.
  • Uses pnputil /delete-driver <oem*.inf> /uninstall (no /force) and reports deleted vs. skipped.
• Driver Restore (20 → 8):
  • Admin-only restore from a DriverBackup_* folder.
  • Validates the path and .inf files, then runs
    pnputil /add-driver "<backup>\*.inf" /subdirs /install.

Execution Policy

• If execution policy is Restricted or AllSigned, the tool relaunches itself with
  -ExecutionPolicy Bypass for the current process.
• On failure it prints the exact PowerShell command the user can run manually.

DNS / DoH

• DNS / Network Tool:
  • Enable DoH configures DoH for known DNS servers and reports how many were applied.
  • Disable DoH removes the encryption entries, flushes the DNS cache, and attempts to restart the DNS Client.

UX / UI

• Main menu shows banners when Dry Run or Dev Mode are active.
• Developer menu includes short explanations for each toggle.
• Utilities menu header cleaned up.
