I'm no Windows expert, but I think by default all packages you install
locally go under:

  /Documents and Settings/username/Application Data/cabal
  /Documents and Settings/username/Application Data/ghc

So you if you didn't install things globally, you may not need to
reinstall the Haskell Platform.  You just move those directories and
they will be recreated.

One of the first things I do after installing GHC is:

$ ghc-pkg check

to make sure things look sane.  If they don't it will tell you to run:

$ ghc-pkg recache

Is this what you're asking?
