#### Overview of the Issue

Build 'googlecompute.win2019_office2021' errored after 30 minutes 51 seconds: Error creating windows password: time out while waiting for the password to be created

#### Reproduction Steps
1. Using the official version (ex: windows-server-2019-dc-v20251112 or windows-server-2016-dc-v20251112), the first-layer image (ex: base-golden-Win2019) is built successfully.

2. Building the second-layer image based on the first-layer image (base-golden-Win2019) results in the following error: Error creating windows password

### Packer version
packer version: Packer v1.9.1

googlecompute version "v1.2.1"

set these:
winrm_timeout = "30m"
windows_password_timeout = "30m"

```

Start by tracing the googlecompute builder's Windows password creation flow and its timeout handling, then reproduce the failure using the reported Windows Server image layering setup and timeout values. Done means identifying why password creation remains in RUNNING state and providing a verified fix or a clear diagnostic outcome.
