MD-102 Practice Question: During a Windows 10 in-place upgrade using…
During a Windows 10 in-place upgrade using Configuration Manager, the task sequence fails with error code 0x800706BE. The smsts.log shows 'Failed to run the action: Upgrade Operating System'. What is the most likely cause?
⚠ Common exam trap
The trap here is that candidates often associate error 0x800706BE with generic setup corruption or disk space issues, but Microsoft specifically documents this RPC error as being caused by third-party security software blocking the upgrade process.

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
✓
Antivirus software blocking the upgrade process
Error code 0x800706BE is a generic 'The remote procedure call failed' error, which in the context of a Configuration Manager task sequence during an in-place upgrade is most commonly caused by antivirus software interfering with the setup process. Antivirus real-time scanning can lock files or block critical RPC calls that the Windows Setup engine requires, leading to the 'Failed to run the action: Upgrade Operating System' failure in smsts.log.

Insufficient disk space on the system drive
Why it's wrong here
Would result in a different error, such as 0x80070070.
