SOLVED Reclaim Disk Space after Windows 7 SP1 install

[Nibiru2012]

When you install Windows 7 SP1 or Windows Server 2008 R2 SP1, it backs up all the files that it replaces. This is done so, if, should you choose to uninstall Service Pack 1 at any point of time, these backed up files are readily available.

However after a couple of weeks, if you are comfortable with SP1 and if you are sure that you will not need to uninstall SP1, then you may wish to consider removal of several 100 MB of such back up files and reclaim disk space.

To do so, open a command prompt with administrative privileges.

To remove the Service Pack backup files online, run the following command:
DISM /online /cleanup-Image /spsuperseded

To remove the Service Pack backup files from an offline image, run the following command:
DISM /image:<path_to_offline_image> /cleanup-Image /spsuperseded

The /spsuperseded option removes the backup files created during installation.
If you wish to simply hide the service pack from the list of installed updates without actually removing the files, use the /hidesp option.

Deployment Image Servicing & Management (DISM) is a new command line tool which was introduced in Windows 7 to manage a Windows image or prepare a Windows PE image.

This is what the "cmd" window looks like after running the "online" process described above.

It's peculiar in the fact that the "cmd" window shows "Microsoft-Windows-UltimateEdition" when I have Professional installed. :hmmmm2:

We shouldn't have to resort to such measures to remove BS leftovers from an install.

Microsoft, that is your mess, learn to clean it up.

Please remember that if you have the Service Pack 1 Beta installed on Windows 7/Server 2008 R2, that you will be Required to uninstall the SP1 Beta before you can install the Final (RTM) version of SP1 when it is released.

Nibiru2012 posted a different thread that gives precaution when removing SP1 Beta.
