Comment (by rpaladugu1):

 You can remove the following message by opening the command prompt as
 administrator and doing the "ghc-pkg recache" in the C:/Program
 Files/MinGHC-7.10.1/ghc-7.10.1\lib folder. It worked for me and the
 message was gone.

 WARNING: cache is out of date: C:/Program
 Files/MinGHC-7.10.1/ghc-7.10.1\lib\package.conf.d\package.cache
 ghc will see an old view of this package db. Use 'ghc-pkg recache' to fix.
