How to removing anaconda from windows completely

I installed anaconda a while ago, but recently decided to uninstall it and just install basic python 2.7.

I removed anaconda and deleted all the directories and installed python 2.7.

But when I go to install pygtk for windows it says it will install it to the c:/users/.../Anaconda directory - this doesn't even exist. I want to install it to the c:/python-2.7 directory. Why does it think anaconda is still installed? and how can I change this?

thanks!
