    No Currently there is no way to reduce the size of the winSxS Folder.



    Considerably higher disk space consumption. The winsxs directory typically starts at several gigabytes in size and continues to grow as applications are installed. Further, there is currently no way to significantly reduce the size of the winsxs directory.

    Wikipedia says it cannot be reduced, but technet blog says something else.

    The only way to safely reduce the size of the WinSxS folder is to reduce the set of possible actions that the system can take – the easiest way to do that is to remove the packages that installed the components in the first place.  This can be done by uninstalling superseded versions of packages that are on your system.  Service Pack 1 contains a binary called VSP1CLN.EXE, a tool that will make the Service Pack package permanent (not removable) on your system,  and remove the RTM versions of all superseded components.  This can only be done because by making the Service Pack permanent we can guarantee that we won’t ever need the RTM versions.
