Hi,
Thank you for writing to Microsoft Community Forums.
I understand that while upgrading to Windows 10, you receive an error ‘Cypress TrackPad app needs to be uninstalled.’ I’ll certainly help you with this issue.
Ideally, if the installation is blocked by an app that doesn’t appear in the installed applications list, it is likely that the compatibility checker is detecting a file that is associated with the app. In this case, we will need to delete the file to continue the installation.
To find out which file is blocking the installation, I would suggest you to refer the suggestions by Edison Pus replied on February 9, 2018 from the thread Windows 10 upgrade can’t complete due to error: “Some apps need to be uninstalled.”
You may also download run this batch file to automatically perform the steps above: https://aka.ms/AppRPS (You should be prompted to download a zip file named AppRPS.zip)
However, if you are using Dell XPS 15Z L511Z, currently, the manufacturer provides drivers up to Windows 8. If we upgrade the computer to Windows 10, you might face some compatibility or performance issues on the computer.
Let us know how it goes.
Regards,
