I just ran the removal on my Dell computer. Gained back almost 3GB. But it said removing windows Ultimate files. I have Home Premium installed. It said the same on my computer which has Professional installed.

Hello Essenbe,

That edition may have also been included in the SP1, and removed since that is not what you had installed.

After Disk Cleanup this kind of folder appears in temp folder 1E226330-84E2-4D21-8013-FE258AB25D62 (name changes every time). Folder includes files from c:\windows\system32\dism folder and this folder copy happens every time when disk cleanup tool calculates space it can recover. Microsoft SP1 support person noticed this too when i ask about it, so if you wonder strange folders in your temp folder, those are sp1 related. Microsoft supports person doesn't have clue why this happens.

Hi!
I was asking myself if method 2 is correct...:

dism /online /cleanup-image /spsuperseded /hidesp

I think there's no need of the /hidesp setting, because it seems to be in excess. In fact, if you look here:
Deployment Guide for Windows Server 2008 R2 with SP1 and Windows 7 with SP1

at section "Removing backup files" they say:

To remove service pack backup files

1. To remove the files online, run the following command:

Code:

DISM.exe /online /Cleanup-Image /spsuperseded

2. To remove the files from an offline image, run the following command:

Code:

DISM.exe /Image:<path_to_offline_image> /Cleanup-Image /spsuperseded

The /spsuperseded option removes the backup files created during installation.
You can use the /hidesp option to hide the service pack from the list of installed updates without removing the files.

...so who is right?

Hello Bubblebobble, and welcome to Seven Forums.

Technically, we are both right since both commands below will remove the SP1 backup files. :)

DISM.exe /online /Cleanup-Image /spsuperseded

dism /online /cleanup-image /spsuperseded /hidesp

However, adding /hidesp at the end of the command will also remove the Service Pack for Microsoft Windows (KB76932) entry in Installed Updates. Theres's no since in having the SP1 uninstall entry there anymore since you cannot uninstall it after deleting the SP1 backup files anyway.

Tutorial update:

It took a liitle bit of working with it, but you can now use OPTION THREE in this tutorial on the first page to remove the Windows 7 SP1 backup files from a installed slipstream Windows 7 SP1 installation.

Thanks Shaun, got 2.7GB back

Installed SP1 from the Windows update.

sfc /scannow didn't find anything.

Hello Dave,

Wow, that's a nice amount to get back.

Where specifically are the Windows 7 SP1 uninstaller files located?
