12 driver packages Lenovo publishes for the ThinkCentre M90a, for Windows 11 64-bit. Newest: Dec 4, 2025.
Each driver page lists the hardware IDs the package supports and the other Lenovo models it is made for. Downloads are the original Lenovo installers. If Windows Update already installed a driver for a device and it works, there is no need to replace it; install a package when a device is missing in Device Manager or misbehaves.
Device Manager shows a device without a driver under Other devices. Its hardware ID tells you which package above it belongs to (how to find the ID); paste it into the search to go straight to the matching drivers.
