My laptop, a Dell Latitude E6510, is fully updated according to Windows Update. However, Service Pack 1 is not listed as an available update. A quick Google search lead me to a Microsoft Knowledgebase Article and listed one cause of the issue as Igdkmd32.sys. This is the driver for the Intel HD Graphics display adapter on my laptop. The article claims that driver versions 18.104.22.1684 through 22.214.171.1241
are incompatible with Windows 7 Service Pack 1.
As suggested in the article, I updated the driver to the latest version available on the Dell website for my model, 126.96.36.1991
. After installing, I still was unable to get SP1 to appear in Windows Update. So then I went to the Intel website and downloaded an even newer driver version 188.8.131.521
... and after installing and rebooting again, still no SP1 to be found.
Is this driver still a known issue that prohibits SP1 from installing, but Microsoft is just too lazy to updated their KB article?
