If Dell has installed a driver customized in any way, this will prevent the generic drivers from the Intel site from being installed. If you have a laptop, this is usually the case. There are ways to get around this, but understand that, if this is a laptop, doing so could stop certain features (often brightness control, for example) from working properly.
If you want to proceed, here is the process you need to follow:
- Download - but do not attempt to install - the driver package you would like to install.
- Disconnect completely from the Internet. Unplug Ethernet cable and/or disable wireless support.
- From the Apps and Features applet, if there is NOT an entry for an Intel Graphics Driver package, go to Step 6.
- Uninstall this intel Graphics Driver package.
- Reboot, keeping Internet disconnected.
- From the Device Manager applet, if there is a Microsoft-supplied (NOT Intel-supplied) graphics driver assigned to the Intel HD Graphics device, go to Step 9.
- Uninstall this Intel-supplied driver (check the box to specify to delete all driver software for the device).
- Go back to step 5.
- Install the driver package that you downloaded in Step 1.
- Reboot (should be asked to do so, but do one regardless).
- Reconnect Internet. Replug Ethernet cable and/or enable wireless support.
- Test.
Hope this helps,
