The Creative Sound Blaster X-Fi Surround 5.1 (SB1090) retains Windows 10 compatibility using legacy USB drivers available via Creative Support, despite being End of Service Life. Installation requires executing the USB_PCDRV_LB_1_02_0001.exe
Alternatives
Daniel_K (famous for modding Creative drivers) released a package for X-Fi USB devices. However, his drivers are not free and require a donation. The standard 1.01.17 driver works fine for most users.

After a successful reboot, signature enforcement will auto-enable. The driver will continue to work.
However, the community discovered that the Windows 8.1 driver works perfectly on Windows 10 – but only if you manually force installation. Microsoft’s automatic driver updates often override it, leading to frustration.
Once the correct driver is installed, the hardware itself is surprisingly resilient.
