In short,

In Windows 8, Press Win Key + X 
- > Select 'Control Panel'
-> Search for 'Trouble shooting'
-> Select 'Troubleshooting history'
-> then select 'Troubleshooting' from top bar (part of path)
-> Select 'Hardware and Sounds'
-> Select 'Hardware and Devices'  - This will run the 'Find and Fix problems with the devices and hardware' - wizard . 

- The wizard will popup 'Enable ... USB driver xxxxx ,  Apply this Fix?' - Select Apply this Fix. It might show this twice - Select apply this Fix.

Now try your touch screen if working.

Also when you browse to 'Control Panel' - > 'Hardware and Sound'  - You should see ' Pen and Touch' link listed.

Good Luck.
