#### Description

I would like for there to exist a winget provisioner for Packer.

#### Use Case(s)

Instead of using PowerShell provisioner or ansible provisioner to configure the software installed on a Windows VM.

- Using the PowerShell provisioner requires writing (and testing) one
- Using the Ansible provisioner requires configuring winrm in questionable ways

#### Potential configuration

Instead of this:

```json
"provisioners": [
{ "type": "powershell",
"inline": ["Set-ExecutionPolicy Bypass -Scope Process -Force"]
},
{
"type": "powershell",
"script": "ConfigureRemotingForAnsible.ps1"
},
{
"type": "ansible",
"playbook_file": "playbook.yml",
"use_proxy": false,
"user": "packer",
"extra_arguments": ["-vvvv",
"-e", "ansible_winrm_server_cert_validation=ignore"]
},
{
"type": "powershell",
"inline": [
"Set-Service RdAgent -StartupType Disabled",
"Set-Service WindowsAzureGuestAgent -StartupType Disabled",
"Remove-ItemProperty -Path 'HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Setup\\SysPrepExternal\\Generalize' -Name '*'"
]
},
{
"type": "windows-restart",
"restart_check_command": "powershell -command \"& {Write-Output 'restarted.'}\""
},
{
"type": "powershell",
"inline": [
"& $env:SystemRoot\\System32\\Sysprep\\Sysprep.exe /oobe /generalize /quiet /quit",
"while($true) { $imageState = Get-ItemProperty HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Setup\\State | Select ImageState; if($imageState.ImageState -ne 'IMAGE_STATE_GENERALIZE_RESEAL_TO_OOBE') { Write-Output $imageState.ImageState; Start-Sleep -s 10 } else { break } }"
]
}
]
```

Please may I have this?

```json

"provisioners": [
{ "type": "powershell",
"inline": ["Set-ExecutionPolicy Bypass -Scope Process -Force"]
},
{
"type": "winget",
"import_file": "manifest.json",
"extra_arguments": ["--accept-source-agreements", "--accept-package-agreements"]
},
{
"type": "powershell",
"inline": [
"Set-Service RdAgent -StartupType Disabled",
"Set-Service WindowsAzureGuestAgent -StartupType Disabled",
"Remove-ItemProperty -Path 'HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Setup\\SysPrepExternal\\Generalize' -Name '*'"
]
},
{
"type": "windows-restart",
"restart_check_command": "powershell -command \"& {Write-Output 'restarted.'}\""
},
{
"type": "powershell",
"inline": [
"& $env:SystemRoot\\System32\\Sysprep\\Sysprep.exe /oobe /generalize /quiet /quit",
"while($true) { $imageState = Get-ItemProperty HKLM:\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Setup\\State | Select ImageState; if($imageState.ImageState -ne 'IMAGE_STATE_GENERALIZE_RESEAL_TO_OOBE') { Write-Output $imageState.ImageState; Start-Sleep -s 10 } else { break } }"
]
}
]
```
