✅ What to do instead

• If you need Windows 7 for legacy software → Use a legit retail ISO from Microsoft (no activation crack) and keep it offline or on an isolated network.
• If you want a modern, secure OS → Upgrade to Windows 10 or 11 (or try Linux like Ubuntu / Linux Mint for free).
• If you already have a valid Windows 7 license key → Download the official ISO from Microsoft (still possible via their Software Download page using your key).
