Your organization uses Microsoft Intune to manage Windows 10 devices. You need to deploy a custom Windows 10 feature update using the Windows 10 Update Rings feature. However, the deployment fails and devices show error 0x800f0905. What is the most likely cause?

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The feature update package is missing prerequisite updates.
Error 0x800f0905 indicates missing installation files for the feature update. This typically occurs when prerequisite updates are not installed. Therefore, the most likely cause is that the feature update package is missing prerequisite updates (Option C). Option A is incorrect because insufficient disk space would result in a different error. Option B is incorrect because the update ring does not involve language settings. Option D is incorrect because a maintenance window would not cause this error.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The device does not have enough free disk space.
Why it's wrong here
Incorrect. Insufficient disk space would result in a different error (e.g., 0x80070070).
- ✗
The device is not set to the correct language for the update.
Why it's wrong here
Incorrect. The update ring does not depend on language settings; language pack issues have different error codes.
- ✓
The feature update package is missing prerequisite updates.
Why this is correct
Correct. Error 0x800f0905 indicates missing installation files, typically caused by prerequisite updates not being installed before attempting the feature update.
- ✗
The update ring is configured with a maintenance window that is too short.
Why it's wrong here
Incorrect. A short maintenance window might cause installation to be deferred, but it would not produce error 0x800f0905.
