Windows 7 SP1 not being offered on Windows Update

service-packwindows 7windows update

I have no option to install Windows 7 Service Pack 1 (SP1) on my computer. Why is the option to install Windows 7 SP1 missing from Windows Update?

I'm less interested in why the option is missing, and more interested in how to diagnose why the option to install Windows 7 SP1 is being hidden.


Following the suggestions in KB2498452 – You do not have the option of downloading Windows 7 SP1 when you use Windows Update to check for updates:

Confirm that Windows 7 SP1 is not already installed and that you are not running a prerelease version of Windows 7 SP1

I am not already running SP1, or a pre-release SP1:

Check for pending updates
Update 976902 may have to be installed on your computer before Windows 7 SP1 will be offered in Windows Update.

I already have 976902 installed:

Verify that an incompatible version of SafeCentral is not installed on your computer
Windows SP1 may not appear in Windows Update if certain versions of SafeCentral are installed on your computer. SafeCentral is a security program that is manufactured by SafeCentral, Inc.

I do not have SafeCentral installed (I've never heard of such a thing):

Check whether you have Intel integrated graphics driver Igdkmd32.sys or Igdkmd64.sys and whether you upgraded the driver

I do not have an Intel GMA:

Make sure that you did not use vLite to customize your Windows 7 installation

I did not use vLite to customize my Windows 7 installation. Again, I've never heard of such a thing.


Update One:

Here's proof that I've checked for updates "today" (3/2/2011):

enter image description here

And that I'm not being presented the option of installing SP1 (I dispatched an update to Silverlight and a fix for Internet Explorer 9 being hosted in a Direct2D or Direct3D application; so updates themselves do work):

enter image description here

Update Two:

I tried the Windows Update Troubleshooter:

enter image description here

Windows 7 Service Pack 1 is still not available.

Update Three:

Here is the tail end of windowsupdate.log. It speaks of Evaluating application rules:

Found 2 updates and 65 categories in
search; evaluated appl. rules of 1324
out of 1832 deployed entities

These must be the rules that say I'm not allowed to see in SP1:

Update Four:

Here's the view from Device Manager (including hidden devices) showing I have just one graphics card:

enter image description here

If I do have a second video adapter, Windows doesn't know about it. And if a second video adapter was preventing Windows Update from offering me from Service Pack 1, then it should be visible is some log file somewhere.


I'm less interested in why the option to install Windows 7 SP1 is missing, and more interested in how to diagnose why the option to install Windows 7 SP1 is being hidden.

The KB article says that SP1 will not be offered if your machine doesn't meet some secret special criteria. How can I discover what that secret criteria is? I presume it is logged somewhere.

Nor am I particularly interested in a direct download link. I want to learn here. I want to be able to diagnose (i.e. in the future) why an update is not being offered.

I'm a superuser here. Rather than others coming up with a checklist of things to try, I want to be able to come up with the checklist.

Best Answer

Are you sure you do not have the mentioned version of the Intel Graphics driver installed? It might be disabled so it does not show in DxDiag.

In my case this was the reason for SP1 not being offered by Windows Update. I once used the onboard graphics so the Intel driver was installed at some time. Then I added a PEG graphics card and disabled the onboard device. So the driver was present but could not show up in DxDiag. I enabled the onbord graphics card again in bios and after rebooting Windows Update found an update for the Intel driver. I installed it and after rebooting and searching for updates again SP1 was offered as it should.


OP Update: This turns out to be the answer. Even though i didn't have the Intel GMA adapter "installed" i did have the "old" driver on my system. Disabling my nVidia PCI Express video card in the BIOS, and enabling the built-in (Intel) adapter, and the Intel graphics card was then installed in Windows:

enter image description here

A check of available updates in Windows Update showed me an update to the driver for my Intel GMA graphics adapter:

enter image description here

Applying the update, restarting, and now i have Windows 7 Service Pack 1 available on Windows Update:

enter image description here

It's unfortunate that no Windows Update Log, or the Event Log, showed that the presence of an old version of a driver is preventing the publishing of an update. i would have hoped that the issue could have been debugged, rather than inferred.
