Free Disk Space By Making Windows Vista Service Pack 1 Permanent

If you are using Windows Vista and have installed the Service Pack 1, you may be losing up to 1GB of space because of old and redundant files Windows has stored. You can easily recover this space by making Windows Vista Service Pack 1 permanent.

To recover almost 1GB of space after you have installed Windows Vista service Pack 1, follow the simple steps listed below.

  • Open a command prompt window.
  • Type in the command vsp1cln(since this executable exists in system32 folder, it’s a global command and can be run from any folder) and hit Enter.
  • Read the instructions and type in Yand hit enter.
  • You should see Vista performing a clean up of old files, once it’s complete you should recover almost 1GB of disk space.

    This is mostly unknown feature and the best part is that upto 1GB can be reclaimed.

      Of course. You make the SP1 permanent in Vista. If the Vista is not there, the question doesn't arise.
