Difficult to completely uninstall v. 9.0

TI 9.0 is amazing persistent.
I did the manual uninstall directions, link is below. Then I searched through the registry for references to TrueImage and Acronis. There I deleted about 20 more values. Then I found two more files in the \windows\system32\drivers directory (tifsfilt.sys and timntr.sys) to be deleted. Then I reinstalled TI 8.0. The application worked fine.
Interestingly when I decided to try TI 9.2323, I used add/remove programs to uninstall v. 8.0. Then, when I reinstalled and started TI 9.2323 after all of this, it still showed the list of two scheduled tasks that I had from my previous TI 9.0 installation. That is persistent

Hello Bill U,

Thank you for choosing Acronis Disk Backup Software.

Please accept my apologies for the delay with the response.

The point is that you most likely have not deleted C:\Documents and Settings\All Users\Application Data\Acronis\TrueImage\Scripts folder Acronis True Image 9.0 scheduled tasks script files reside in.

Please let me know if that's not the case.

Please also let me know the reason you decided to uninstall Acronis True Image 9.0 manually for.

Thank you.
