Thank you for posting on HP Forums,
The Riddle_Decipher is at your service.
As I Understand you want to know how to use the touch screen instead of the mouse & keyboard,
No worries as I'd love to help, however, I need a few more details to provide an accurate solution:
What exactly do you mean by converting keyboard and mouse to touchscreen?
Do you mean, stopping the usage of keyboard and mouse, using the touch instead?
What is the product number of your device & Which operating system are you using? Use this link to find your product number: http://support.hp.com/rs-en/document/c03754824
(Do not share any personal information such as serial number, email ID, phone number or address on a public forum for your safety).
The reason I need the product number is because I pulled your PC specs using the model name you had mentioned and this is what I found: Click here
And I'm afraid this doesn't support a touchscreen interface (please correct me if I'm wrong).
Keep me posted,
If the information I've provided was helpful,
Give us some reinforcement by clicking the solution and kudos buttons,
That'll help us and others see that we've got the answers!
Good Luck.
