Sysprep was not able to validate your Windows installation

Sysprep was not able to validate your Windows installation. Sysprep can be really useful if you want to save up some time and automatically deploy an operating system on a group of computers. On a machine running Windows 8, 8.1, 10 or even Windows Server 2012, 2012R2 or 2016 you can get an error when syspreping the machine. 然而, when you are faced with one of its issues, it can be, at times, an obstacle to pass. You can learn how to deal with the issue by going through this article.

Sysprep was not able to validate your Windows installation. (Error 0x8007139f)

So, look in C:\Windows\System32\Sysprep\Panther and open the “setupact.log“ 文件:

Error [0x0f0036] SYSPRP spopk.dll:: Sysprep will not run on an upgraded OS. You can only run Sysprep on a custom (clean) install version of Windows.

Error [0x0f0082] SYSPRP ActionPlatform::LaunchModule: Failure occurred while executing ‘Sysprep_Clean_Validate_Opk’ from C:\Windows\System32\spopk.dll; dwRet = 0x139f

Error SYSPRP SysprepSession::Validate: Error in validating actions from C:\Windows\System32\Sysprep\ActionFiles\Cleanup.xml; dwRet = 0x139f

Error SYSPRP RunPlatformActions:Failed while validating SysprepSession actions; dwRet = 0x139f

Error [0x0f0070] SYSPRP RunExternalDlls:An error occurred while running registry sysprep DLLs, halting sysprep execution. dwRet = 0x139f

Error [0x0f00d8] SYSPRP WinMain:Hit failure while pre-validate sysprep cleanup internal providers; hr = 0x8007139f

What we see here is that for some reason Windows thinks it has been upgraded.

Well, if you navigate to the file specified in the error message and go through it, you will find the possible cause of the error. In different scenarios, it can vary, therefore, for a basic insight, it is often due to the following factors:

• Windows Store apps: In some cases, the error occurs if you have downloaded an app from the Windows Store which is preventing the tool. Mostly, Candy Crush and Twitter were found to be the culprits.
• Default Windows apps: Another reason due to why the error occurs can be the removal of default Windows applications. If you have, prior to running Sysprep, removed any Windows default app, that might be the cause of the error.

解决方案 1: Windows Registry Editor

导航至:

HKEY_LOCAL_MACHINE\SYSTEM\Setup\

In the Setup node you will find a REG_DWORD «升级» with a value of probably “0透明 (meaning not an upgrade…)

Just delete the «升级» key and you are good to go!
