vistaInstalling service packs in Windows Vista is somewhat a  funny task. As a matter of fact, it is very exciting to try new things out  and see if the claimed improvements and enhancements really work out-of-the-box! Once you know where to get the SP packages you end up trying pre-beta and RTM (release to market) which, despite  they are not the definitive service packs are able to give you some hints  of the real, future, stable release. But what happen when the definitive service pack rolls out? You are compelled to install it, of course. Usually, after installing a new SP you will notice that a considerably portion of your hard disk has been irremediably taken by the installation itself. Well, this is not completely true. As a matter of fact, a lot of space is still occupied by those files belonging to the previous RTM or SP. All you need to do is some housekeeping!

To remove unwanted backup files belonging to previous service packs ( hey, this is also true when you install Vista SP2 on a machine having already Vista SP1!) follow this simple procedure to activate and use Service Pack Cleanup Tool.

  1. Click Start.
  2. In the search box, type cmd and press Enter. Now you should be able to see the black window belonging to the command prompt DOS.
  3. Type cd..
  4. Re type the command till you just get to the main root C:\
  5. Now type cd Windows
  6. cd System 32
  7. Compcln.exe
  8. Now the system will ask the user if he wishes to make the SP2 installation permanent.
  9. Type “Y” and Vista will start cleaning the hard disk from  useless components.
  10. After that you will notice that your hard disk has got more space.

If instead you wish to make your Windows Vista SP1 installation permanent, click here.
