Windows 10 fails to update to v 1151: Error 0xC1900101 – 0x30018

If you have failed to upgrade Windows 8.1 or Windows 7 to Windows 10, or if your Windows 10 update to version 1511 has failed with error codes 0xC1900101 – 0x30018, then this post may shed some light on the subject.

We couldnt install Windows 10 0xC1900101 0x30018 SYSPREP

The message you see could be:

We couldn’t install Windows 10. We’ve set your PC back to the way it was right before you started installing Windows 10. 0xC1900101 – 0x30018. The installation failed in the FIRST_BOOT phase with an error during SYSPREP operation

This problem was first noticed around August 2015, when users wanting to upgrade Windows 8.1 or Windows 7 to Windows 10 had faced this problem. Microsoft had responded to this issue, stating that:

We are currently working with our partner companies to help update problematic drivers whenever they are identified. We understand that the inability to easily identify the incompatible driver can be incredibly frustrating and we are sorry for the inconvenience.

However, it appears that some users are facing this issue, even when they try to update Windows 10 to version 1511.

The Sysprep or System Preparation Tool is basically meant to automate the deployment of Windows operating system. Given this bit of information, here is what you may try:

1] Run System File Checker and DISM to repair corrupt System Image.

2] Some software like DAEMON Tools, TuneUp, Folder Locker software, etc, are known to interfere. Uninstall them and see if it helps. Make sure you unlock your folders first. Also disable your antivirus software and Firewall temporarily.

3] Remove all connected USB devices  – this excludes the keyboard.

4] In case you are well-versed with the Windows OS, then you may take a look at these hidden log files. They may offer some direction to work on:

  • $Windows.~BT\sources\Panther
  • $Windows.~BT\sources\Rollback

5] If nothing helps, if you received this error while using Windows Update, use the Media Creation Tool and see if that make the installation go through.

All the best!
