Hello,
Welcome to Microsoft Community.
We apologize for the trouble and bad experience you had.
We need more information to pinpoint the problem, may I ask if the error 0x80070643 is it an error with one update installation prompt or if there are multiple updates that should be reported?
Also, please provide us with the current Windows version of your Surface Pro7.
Regarding the Intel Precise Touch Device Driver you mentioned, which is one of the Surface firmware drivers, I suggest you visit the link below to download the Surface Pro7 firmware driver and reinstall it to see the effect (the firmware was last updated on 3/11/2024)
Download Surface Pro 7 Drivers and Firmware from Official Microsoft Download Center
In addition to that, please click on the link below to download the Surface Hardware Diagnostic Kit, which is able to detect problems with touchscreen/stylus writing, let's see what the problem is when the diagnosis is displayed. https://aka.ms/surfacerepairuwp
Thank you for your patience and understanding, and feel free to let me know if there is anything unclear.
Reagrds,
Manson | Microsoft Community Support Specialist
