If you want a safe, official Windows 7 Professional 64-bit system, you should be looking for Windows 7 Professional SP1 (Service Pack 1) , followed by the Convenience Rollup update.
⚠️ Do not attempt to install the Convenience Rollup on a fresh, non-SP1 Windows 7. It will fail.

A: Because SP2 was never officially declared. The OS version remains 6.1.7601 (SP1).
If you still have the original computer that came with Windows 7 Professional, check if the recovery partition is intact. Usually, pressing a function key (like F11, F8, or F12) during boot will allow you to restore the PC to its factory settings, which includes the correct version of Windows 7 Professional.
Correction for clarity: To truly emulate SP2, download the latest (e.g., January 2023 ESU). However, for most users, the 2016 Convenience Rollup is stable and free (does not require ESU licenses).
