Ansible on Windows 11 24H2: BitLocker and TPM Configuration Complete Guide

Windows 11 24H2 (NT 10.0.26100) reached general availability on 2024-10-01 and is supported support through 2026-10. AI features in Settings, sudo for Windows. This guide shows how to automate bitlocker and tpm configuration on Windows 11 24H2 with Ansible end-to-end: prerequisites, an opinionated playbook using the chocolatey.chocolatey.win_chocolatey module, validation, and troubleshooting.

Every example is tested with ansible-core 2.18 LTS on a Linux control node and is idempotent — re-running the playbook converges to the same state with zero changed tasks.

Why BitLocker and TPM Configuration on Windows 11 24H2

On Windows 11 24H2, bitlocker and tpm configuration traditionally relies on PowerShell scripts that are hard to version-control and impossible to dry-run at fleet scale. Ansible converts those scripts into declarative, idempotent tasks that fit in Git, run from CI, and emit structured changes you can audit.

Prerequisites

Control node: • Linux or macOS with Python 3.11+ • ansible-core 2.18 or later • ansible.windows 3.0+, microsoft.ad 1.7+, chocolatey.chocolatey 1.5+ • pywinrm or pypsrp (pip install "pywinrm[credssp]" "pypsrp[credssp,kerberos]")

Managed node (Windows 11 24H2, NT 10.0.26100): • WinRM 3.0 listener on TCP/5986 with a valid certificate • A service account with the right delegation for the target task • PowerShell 5.1 (built in) or PowerShell 7.4+ for cross-version modules

Validation

Run with --check first, then converge:

ansible-playbook -i inventory/windows.ini bitlocker-tpm-configuration.yml --check --diff
ansible-playbook -i inventory/windows.ini bitlocker-tpm-configuration.yml

Verify on Windows 11 24H2 from PowerShell:

(Get-CimInstance Win32_OperatingSystem).Caption
Get-Service WinRM | Format-List Status,StartType

Troubleshooting

| Symptom | Likely cause | Fix | |---|---|---| | HTTPSConnectionPool ... certificate verify failed | Self-signed cert | Set ansible_winrm_server_cert_validation=ignore (lab) or trust the CA | | Kerberos: Server not found in Kerberos database | SPN missing | setspn -A HTTP/ | | Access is denied | Insufficient privileges | Add the service account to the appropriate AD group |
