If the MATLAB uninstaller was unable to complete, try executing the uninstall.exe from $MATLAB\uninstall (where $MATLAB is the folder where MATLAB is installed). For example:
C:\Program Files\MATLAB\R2014a\uninstall\bin\win64
If you are unable to complete the uninstaller, you can manually delete the MATLAB installation folder.
Afterwards, you can remove the MATLAB entries from the Windows System Path. For help modifying the Path in Windows, see the related article:

And how to we "safely" remove all of the drek that gets added to the registry if we have to resort to the "delete the matlab folder" option of blowing away a version of matlab that can't be installed "cleanly"

I'm pretty sure MATLAB adds nothing to the registry other than borrowed license keys. That has it's own set of troubleshooting.

They don't add much, but there were about 50 entries in the registry that reference either matlab or mathworks. I don't think many of them are "important" enough to affect performace, but bloat is bloat.

Yes indeed, a bloat is a bloat, I was trying to uninstall R2019b, what a hassle !!! nothing in the "help" or "support" did help. I right-clicked on the MATLAB folder under program files, selected properties, uncheck the read only button, wait until it finishes to update the selection. I deleted all folders in MATLAB, one by one (what a hassle !!!!), I made sure all is gone ...a rather primitive approach (a bloat), I used CCLEANER registry clean to wipe all the registry keys, I installed a new version R2020a, selected only the minimum required toolboxes, and all done. It's was a day worth of work of my time, it's disappointing to see the software growing on you and busting all your GB space...maybe it will replace Windows or your OS in the near future !!
