Well, As far as my little about Computers goes, I do not think any specific methods to make an ordinary monitor to a touch screen monitor leave alone the Software or Operating System to make so. The touch screen monitors are specially designed one, as far as I know. However, you are entitled to your opinion and if anything positive like you think comes out, please share the same successful information [after you testify it] in the Forum of www.MyWindowsClub.com for the benefit of all our members here.
Soon expecting a testimony on this subject from you. Other members may also help this member in finding out the specific information and share the same here.
My best wishes.
Satish Kumar Pranatharthyharan,
Superintendent of Central Excise & Customs.
