Sometimes the installer finishes but misses a specific driver. Navigate into the BootCamp > Drivers folder on your USB and look for the Broadcom or Intel folders. You can manually run the .msi installers for the specific components that are failing. Windows 10 Compatibility
While this version is officially for Windows 7/8, many users have successfully used it to stabilize Windows 10 on 2013/2014 Macs. However, if you are on Windows 10, Apple generally recommends using the Apple Software Update tool within Windows to pull the 6.0 drivers instead.
The Boot Camp Support Software 5.1.5621 is the "goldilocks" driver set for 2013–2014 Mac owners. It ensures that your Windows partition feels as smooth and integrated as your macOS partition. If you are refurbishing an older machine or need a stable Windows 7 environment for legacy software, this download is a must-have in your toolkit.
Fix: Open Boot Camp Control Panel → Keyboard → Enable “Turn on keyboard backlight when the computer is in low light.” Ensure the ambient light sensor is clean.
With Apple transitioning fully to Apple Silicon (M1, M2, M3, M4), Boot Camp is no longer being developed for new Macs. However, the Intel-based Macs that rely on version 5.1.5621 will be in service for years—especially in schools, studios, and enterprises. Expect community-driven forums and GitHub projects to maintain and patch this version for security issues.
Security advisory: Since 5.1.5621 includes drivers from 2013–2014, some may have known vulnerabilities (e.g., CVE-2019-8590 in audio drivers). If you use this version, isolate the Windows partition from the internet or use a robust firewall.
Cause: Power management settings conflict with the Broadcom BCM4331 driver in 5.1.5621.
Fix:
Short answer: Yes, with caveats.
If your Mac is compatible with a newer Boot Camp version (e.g., 6.x), you should upgrade. But for many users stuck on Windows 7 for legacy hardware/software, 5.1.5621 is the final, stable release.

However, for security and performance, most users are encouraged to move to Windows 10/11 with Boot Camp 6.x (or newer Apple Silicon workarounds like Parallels/VMware) on supported hardware. On unsupported Macs, version 5.1.5621 may represent the last stable driver set.
