I heard that Microsoft released Windows 7 Service Pack 1 yesterday. By sheer coincidence I planned to format and reinstall Windows 7 on my PC, next week.
Is it possible merge (slipstream) the original Windows 7 installation and the new Service Pack 1 in a single ISO image?
Note: Bonus points if you suggest a method that works also for Windows XP.
Answer
WARNING: YMMV. I think we're close, but not quite there yet. These instructions have worked for some people, but I'm getting an error on the last step. So I think we're missing something. It's getting late here, I'm going to flag this as a community wiki. Perhaps you can sort out what I've missed.
Windows 7 slipstreaming is not officially supported. You can use third party tools to accomplish the task. You can also do it yourself manually by unpacking the cab files, editing three text files, and using dism
command to update the installation packages. Here's how to do that step by step:
Copy
install.wim
from your installation disc to your hard drive.Go to the download Windows 7 Service Pack 1 webpage on the Microsoft website, and then click Continue.
After you have passed the "Genuine Advantage" test, you can choose to download either
windows6.1-KB976932-X64.exe
, or the 32-bit versionwindows6.1-KB976932-X86.exe
Extract the contents of the service pack with the
-x
command. Example:windows6.1-KB976932-X64.exe -x
Extract the contents of
windows6.1-KB976932-X64.cab
with a tool like 7-Zip (any compression utility that supports cab will do).Extract the contents of
NestedMPPContent.cab
into the same folder.Open
update.ses
in notepad and changeAbsent
intoInstalled
underOfflineInstall
. It should look like:
Open
update.mum
andWindows7SP1-KB976933~31bf3856ad364e35~amd64~~6.1.1.17514.mum
(or the 32-bit equivalent) in notepad and changeallowedOffline="false"
toallowedOffline="true"
Extract all the language cab files
KB976933-LangsCab0
throughKB976933-LangsCab6
, overwrite files if prompted.Launch a command prompt with Administrative privileges.
Let's assume you stored the extracted service pack files in a folder called
C:\sp1
. Create a new folder calledC:\offline
, and note the location ofinstall.wim
which should be in the sources folder in your Windows 7 installation disc contents. Use the following commands (change folder names where necessary:DISM /Mount-Wim /WimFile:C:\win7-contents\sources\install.wim /Index:1 /MountDir:C:\offline
DISM /Image:C:\offline /Add-Package /PackagePath:C:\sp1
DISM /Unmount-Wim /MountDir:C:\offline /Commit
