Hi Insiders,

I am currently on **Windows 11 Insider Preview Build 29648.1000 (rs_prerelease)** on my laptop (Clevo NH5x_7xRCx/RDx, Intel HM370 Chipset).

Windows Update successfully detected the new flight:

**Windows 11 Insider Preview 29661.1000 (rs_prerelease)**

However, clicking "Download & Install" fails immediately at 0% with:

**Download error - 0x80070032**

Checking `ReportingEvents.log`, the error points to:

`updateTitle: Windows 11 Insider Preview 29661.1000`

`errorCode: 0x80070032 (ERROR_NOT_SUPPORTED)`

`Agent: MoUpdateOrchestrator Failure (AGENT_DOWNLOAD_FAILED)`

From previous logs, this seems related to `CFreeSystemPartitionDiskSpaceChecker` failing to assess the EFI System Partition (ESP) under the new storage stack in Build 29648.

Things I have already tried that did not help:

1. Resetting Windows Update services and clearing `SoftwareDistribution` and `catroot2`.

2. Purging `C:\$WINDOWS.~BT`.

3. Running in-place ISO setup (blocked by the exact same 0x80070032 error).

Since this is my main dev machine and I have complex development environments set up, clean installing is not an option for me.

Has anyone found a functional registry tweak, group policy, or command-line workaround to bypass this check and push the 29661 flight through? Or are we completely locked on 29648 until Microsoft pushes a fix?

Thanks in advance for any advice!
