Observations for Windows 7 Service Pack 1 Error 0x800f0a12

During the past days I have been manually updating a few Windows 7 clients and on two of them I received the error 0x800fa12.

When clicking on the Go online link Microsoft mentions the several reasons that could lead to this error.

 The system partition isn’t automatically mounted, or made accessible to Windows, during startup.

 A hard disk containing the system partition was removed prior to beginning SP1 installation.

 Windows is running on a storage area network (SAN), and access to the system partition has been disabled.

```
 A disk management tool from another software manufacturer was used to copy (or clone) the disk or partition on which you’re trying to install SP1

Knowing my systems I could immediately exclude cause 2,3 and 4, so took a closer look at cause 1. Running the command MOUNTVOL /L showed the following result:

Removing Backup Files Created during Windows 7 Service Pack 1 Installation

For the Windows Vista Service Packs there was vsp1cln.exe (SP1) and compcln.exe (SP2) to cleanup the backup files created during the Service Pack installation. For Windows 7 Microsoft did not provide a separate cleanup tool, but instead leverages the windows-build-in DISM tool.

To remove the backup files created during the Windows 7 Service Pack 1 installation run the following command from an elevated command prompt.

dism.exe /online /cleanup-image /spsuperseded

After successful completion you should get some disk space back.

I wrote about BITSADMIN earlier, use the below command line to directly download Vista SP1. Note that you have to create the c;\download folder yourself or define an other path.
