- Next, dasHost.exe searches the Windows Update library for drivers with the same IDs as the device.
- The file will then download a driver to your machine if it finds one in the Windows Update catalog.

3. Overseeing device association
When connecting an unknown device to your laptop or desktop, dasHost.exe first looks for the device’s driver. If a driver is found, the file will install it and then associate the device with the driver. This enables the device to work correctly on your computer.
