Hello EmNof,
I'm Jin, a fellow Windows 10 user and an independent advisor. I'm sorry to hear that the touch screen of your laptop doesn't work after an update.
You can download your device's driver at
https://support.lenovo.com/ph/en/downloads/ds11....
This is a non-Microsoft website which would provide accurate and safe information. Watch out for ads on the site which are frequently classified as a PUP (Potentially Unwanted Products). There is no need to buy paid products to fix your computers as they do more harm than good sometimes.
If reinstalling the drivers doesn't work, you can rollback your Windows 10 to its usable state.
1. In the search box on the taskbar, type control panel, and then choose it from the list of results
2. In the Control Panel search box, type recovery.
3. Select Recovery > Open System Restore.
4. In the Restore system files and setting box, select Next.
I hope this helps.
