There are some uninstall tools, of varying quality. Some depend on you 
having been running them while the install happened, which is probably 
not the case for you. Once you've messed up Windows' idea of the install 
subsystem, it's not that easy to recover. Though some may disagree, 
that's not really Python's fault, the install system seems pretty 
fragile.  Sometimes if the the files needed to process the uninstall 
have been removed but the uninstall itself didn't finish you're in 
trouble - which isn't really the fault of the install system, but then 
you ask how that scenario arose? anyway...

You could look for this tool: 
MicrosoftProgram_Install_and_Uninstall.meta.diagcab - an Internet search 
should find it. it usually does a fairly good job of cleaning up messes 
(well - it's worked well for me in a few dire situations).
