You can download the latest driver for you system here: Download Intel® Beta Graphics Driver for Windows® 7/8.1/10* [15.40]

You are required to install drivers from your computer manufacturer; however, you may try forcing the installation of Intel generic drivers by performing manual procedure, see here for instructions: How to Manually Install an Intel® Graphics Driver in Windows® 10 &...
Note: Once you install the “generic” driver you will overwrite any customizations your system manufacturer made to the driver specific for your system model.
