You have to use the Have Disk Option No? just browsing to, the directory with update driver gave me the already have the latest message.Worked for me every time. I never had to uninstall previous driver, using the zip download works fine.
Don't install it unless you cant live without some feature it provides. its not Connected Standby optimized so you'll give up battery life. my experience was that my CPU/GPU temp ran 10c hotter and the Sleep study said Intel HD Graphics was active during sleep.What's the reason to install this driver?
Ok, I had the drivers from the Intel site installed most of this morning, I went to reboot my computer about 10 minutes ago and it was saying update and restart so I did this and its reverted back to the stock drivers! Is there anyway to stop it doing this?
