Really? I spoke to Lenovo and they said they were working on the problem. On the other hand my machine is much faster. The UI is quite a jump for me over Windows 8.1 was and the Edge must be cached I figured because it is near instantaneous. I really like Windows 10 because of the speed boost and don't use the Touch much . I wonder if you are using an old driver somehow. it is strange how they are all different. There are different version of the U530 Lenovo said. Mine is the I7 with 8GB ram and the hybrid drive as well. It also has the Nvidia card but they said there are 4 flavors of the U530 so maybe that has something to do with it. Overall Windows 10 was a nice jump.
My U530's model name is: 20289; this too has 8GB RAM and i7-4510U CPU with the hybrid drive.
I checked the touch screen driver in Device Manager and it's an ancient one from 2006!! Here are its details:
HID-Compliant touch screen
Provider: Microsoft
Driver Date: 6/21/2006
Driver Version: 10.0.10240.16384
Digital Signer: Microsoft Windows
