title: Problems in fully uninstalling Python 2.7 from Windows 7
body: <p>some months ago, I installed Python 2.7 on my laptop (my os is Windows 7). 
  After, I decided to use Python xy 2.7.3 instead of 'pure' Python; so, as suggested, I removed Python 2.7 and tried to install Python xy 2.7.3. However, when I tried to run the .exe file for installation, a warning window appears telling me that Python 2.7 is already installed on my computer. I tried to install a different version of Python xy (2.6) and everything went fine; however, I'd really prefer to use the latest version of Python xy. 
  Actually, I can't figure out what went wrong whie uninstalling Python 2.7; does someone have any clue?
  I can tell you that I followed the 'normal' procedure for programm uninstalltion; control panel -> Programs -> Remove Program</p>
  
  <p>Thanks in advance</p>
