| Symptom | Likely Cause | Resolution | |----------|--------------|------------| | | Bad installation media (corrupt ISO or USB) | Verify the SHA‑256 hash; re‑burn the media. | | Missing network driver after install | Driver not included in the integrated image | Boot into Safe Mode, load the saved driver pack, and install manually. | | Activation fails with “0xC004F074” | KMS server not reachable or time‑drift | Ensure the workstation can contact the KMS server; sync the system clock via w32tm /resync . | | BSOD with STOP code 0x0000007B (INACCESSIBLE_BOOT_DEVICE) | Incompatible SATA mode (IDE vs. AHCI) | Change BIOS SATA mode to the one used during install, or inject the correct driver with DISM. | | Windows Update refuses to download | The machine is no longer receiving updates (EOL) | If you have an ESU agreement, point the client to the ESU WSUS server; otherwise, rely on the offline ISO for security. | --- Windows 7 Service Pack 3 Iso Download 64-bit Offline
