+# Win2025-Sysprep
+
+Files for building a reusable `Win2025-Sysprep` template for vSphere, Terraform, and Ansible Semaphore.
+
+## Included
+
+- `scripts/Prepare-Win2025Sysprep.ps1` prepares Windows Server 2025 for templating.
+- `files/unattend.xml` is the answer file used by `sysprep`.
+
+## Manual prep before running the script
+
+1. Install Windows Server 2025 in a dedicated VM.
+2. Install VMware Tools.
+3. Sign in as local `Administrator`.
+4. Apply Windows updates and any baseline OS settings you want baked into the template.
+5. Copy this folder to the VM, for example `C:\Build\Win2025-Sysprep`.
+
+## What the script does
+
+- enables WinRM for Ansible;
+- opens firewall rules for WinRM and RDP;
+- enables RDP;
+- enables the built-in `Administrator` account;
+- switches network profiles to `Private` when possible;
+- cleans temporary files;
+- generates `unattend.xml`;
+- runs `sysprep /generalize /oobe /shutdown`.
+
+## Run
+
+Open PowerShell as Administrator and run:
+
+```powershell
+Set-ExecutionPolicy Bypass -Scope Process -Force
+cd C:\Build\Win2025-Sysprep
+.\scripts\Prepare-Win2025Sysprep.ps1
+```
+
+If you want OpenSSH installed too:
+
+```powershell
+.\scripts\Prepare-Win2025Sysprep.ps1 -InstallOpenSsh
+```
+
+If you want a different timezone:
+
+```powershell
+.\scripts\Prepare-Win2025Sysprep.ps1 -TimeZone "Russian Standard Time"
+```
+
+## After the VM shuts down
+
+1. Confirm the VM is powered off in vSphere.
+2. Convert the VM to a template.
+3. Name the template `Win2025-Sysprep`.
+4. Use that name in Terraform variable `vm_template`.
+
+## Checklist before converting to template
+
+- VMware Tools are installed and healthy.
+- WinRM is responding.
+- The VM shut down because of `sysprep`.
+- The VM is not domain joined.
+- No machine-specific secrets or unique data remain on the server.
+
+## Quick WinRM check
+
+Before running `sysprep`, you can verify locally:
+
+```powershell
+winrm enumerate winrm/config/listener
+Test-WSMan
+```
+
+## Notes
+
+- The computer name inside the source VM is not important because Terraform `windows_options` will rename cloned VMs.
+- Do not join the template to the domain in advance.
+- If you plan to use WinRM over HTTPS, it is usually better to issue the certificate after cloning, not inside the golden image.
