Intel — Intel integrated graphics driver

When blamed in a crash: Very likely the true cause

What to do

Intel's integrated-graphics driver. Update it from Intel or your laptop maker.

Run the Intel Driver & Support Assistant, or get the driver from your laptop maker's support page.
If crashes began after a Windows update, install the newest Intel graphics driver anyway — mismatches between the two cause exactly this.
On laptops with dual graphics, update both GPUs' drivers.
