# How do I clear my existing environment?
If you already have installed some packages from Hackage or elsewhere and you want to start from a fresh package set, you can remove your `~/.ghc/<os>-<ghc-version>` directory.
For example, in my directory `.ghci` I have:
$ ls ~/.ghc/
x86_64-linux-7.2.2 x86_64-linux-7.4.2 x86_64-linux-7.6.2 x86_64-linux-7.6.3 x86_64-linux-7.8.2
If I want to clear my GHC 7.2.2. environment, all the user-installed packages, I can remove the directory `x86_64-linux-7.2.2`. **Be careful** that you are sure that you want to clear your package set (re-installing packages takes time!) and that you clear the right one.
On Windows the `.ghc` directory might be in a directory like `C:\Documents and Settings\HaskellCurry\`.
Now you can set Stackage as your `remote-repo` and run `cabal update`.
