I installed IOBit Driver Booster on my desktop the other day and it seemed to fix a lot of old drivers which was good so I installed it on a few more PC's one was my Asus EP121 tablet which is an older Windows 7 (originally) tablet. Driver Booster totally replaced the tablets touch drivers with a USB touch interface which is like using your finger as a mouse and nothing like using a touch screen. I have a 8 inch portable monitor that features the usb touch and frankly it isn't worth using as a touch screen in my opinion it is terrible and nothing like how touch should be. Anyway I reinstalled the touch drivers for my tablet and that fixed everything up but users should beware that programs like this can have negative effects on your system my IOBit even told me it was creating a system restore point but when I went to use it this morning I couldn't find where it had created it at to utilize it. So unless you know how to fix driver issues on your own I would suggest being cautious when using this program.
