Drivers need to support windows 7 to work properly. Some of the drivers you install may work fine because they do support windows 7. The intel chipset driver for this model I opened and in the license agreement is states it the operating systems it supports and includes windows 7. So you just need to download the drivers and validate that they support windows 7. Most if not all the "win 10" drivers will probably support windows 7.
