@RedPa To confirm, did you check if the touchscreen works in the BIOS Screen? And by that I mean not only in the right corner but every where?
This would help us determine if this is either a software or hardware related issue, hence I request you tap on F10 during a PC restart and check if you can use the touch feature to select options outside windows.
If it doesn't work, this could be a hardware malfunction.
If it works, please use the HP website to download all the latest drivers for your device using this link: click here (since you haven't mentioned where you got it from)
