Why aren’t all my apps or devices listed?

If some of your apps or devices aren't listed in the compatibility report shown in Windows 8.1 Upgrade Assistant, it might be because Microsoft doesn’t have enough info from the app developer or device manufacturer to determine compatibility for that app or device yet.

If devices are missing from the compatibility report, try connecting those devices to your PC, close the Upgrade Assistant, and then download and run it again. If your devices still don't appear in the compatibility report, search for each of them in the Windows Compatibility Center to see if they’re compatible with this version of Windows, or contact the app or device manufacturer for this info.
