I could not uninstall MATLAB. How do I uninstall MATLAB completely from my computer?

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 try the following workarounds:
1) Re-install MATLAB and overwrite the current MATLAB folder. This will re-create uninstall.exe and should allow you to uninstall once complete
2) Manually delete the MATLAB installation folder.
Aside from removing the installation of MATLAB, 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.
