The new MS Surface Firmware Update installed on Jan 15th 2015, and now the Touchscreen isn't working. I've tried Uninstalling the Firmware via Compmgmt, System Restoring to an earlier point in time, etc. Windows Update is showing error Code 8024CE0A. In Compmgmt the Surface Pro Touch Controller has the yellow exclamation point next to it. Anyone else having this issue? Has anyone been able to resolve it?
