Here's something I found from 2 years ago......
I may have found a secret way to really uninstall a state. There are Microsoft Installer (MSI) files hidden way down deep. For California, for example, I found
C:\ProgramData\Intuit\Common\Update Service\v4\Data\f014b69628c54554802fa15380418f53\C\C-wcaiper\012.000.1017_msi\v1\F\wcaiper.msi
You'll have to look through all the cryptic folders to find unwanted states. Or search for w*.msi under C:\ProgramData\Intuit\Common\Update Service\. Some of the results will be for prior years.
Of course, I want to keep CA. But I also found the Rhode Island version of this .MSI file, right-clicked on it, and ran Uninstall. It seems to have worked. All traces of the string "wriiper" vanished from my Windows registry. Updating TT did not download RI state. And running the State Taxes section of TT shows no more RI.
