Laggy/slow after Intel High-Definition (HD) Graphics Driver update

HP Supports Assistant shows that I need Intel High-Definition (HD) Graphics Driver - sp72370 driver for my Envy 360. Before I install this driver I can see that things are a bit laggy, ofcourse I dont have graphics driver. So I install this driver and everything works fine. However, Windows Update (always) pushes an update to this driver namely Intel Corporation driver update for Intel(R) HD Graphics Family (This driver was provided by Intel Corporation for support of Intel(R) HD Graphics Family), and the moment the update is installed everything goes down. The laptop starts lagging, the lag is visible while opening drives and programs, especially Firefox becomes a mess. Typing becomes terribly laggy, you cant shift to tabs quickly, page opening is slow like hell.

Ony because of this lag I had to clean install Windows 10 thrice as I though that it will fix the problem. I had to run ChkDsk for quite a few times on my 750 GB HDD. But then by hit and trial I narrowed down the problem to this Update, and we all know now it cant be uninstalled either. Please help.
