Portable Cleaner - does it still use the registry ? Is 30% CPU load fixed ?

In General Discussion (off topic) Anything and everything… I saw this Posted on: September 10, 2009
Re: Services.exe at 30% CPU and high memory usage

I was about to use the Portable version running on a non-system partition or Flash Drive :-
CSC_SETUP_2.0.111095.7_xp_vista_server2003_win7_32bit.zip

Please advise me does this later version :-

  1. Resolve the 30% CPU problem ;
  2. Does it still put keys / Values in the Registry ;
  3. If I press the Update button, will it launch the installer for the latest NON-portable version.
