RE: IGFXEM Module stopped working in Dell 7020
I found this testing it out myself. I will post back.
After searching websites, including this, nothing I found that could help me fix this issue. What I did was uninstalled the Intel HD 4600 Drive from the Device Manager,
and make sure to check the box to uninstall the software. After the uninstall, restart your computer. The Device Manager will show MS generic display, under Display adaptor.
Then click on Windows Updates to get the latest drivers for Intel HD 4600. The driver for the Intel HD 4600 that I updated through Windows Update is 10.18.14.4264.
The igfxTray Module does not appear after turning off the laptop and back on. I've been using it for a few days without any issues.
