In Device Manager, find your device when in fastboot mode (it may show as "Android" with a yellow triangle).
Right-click > Update driver > Browse my computer > Let me pick > Select "Android Bootloader Interface" from the list.

Post-installation check:

Open Device Manager → look for Sony sa0106 (Flashmode) or Android Bootloader Interface (Fastboot) when device is connected appropriately.
