Vista saves previous installations (How to remove also)

Saved Information or Installations.
Once you format or Reformat, which ever you prefer, you will start clean. Although lets pretend you forgot your family photo's and you just reformatted. Now what do you do? Are you stuck without your important photo's? NOPE. You can now go to your previous installations and pull out anything you have forgotten. You can do this by going to My Computer-->C:Drive--> they will be named Windows.old. This is a nice feature in vista, i love it, and it stays there until you get rid of it which brings me to my next step.

How to remove old Vista installations.
To remove previous Windows installations, you MUST go to Start-->Accessories or use search-->System Tools-->Disk Clean-up (Search this). Let it scan and CHECK ALL the boxes, yes i said EVERY BOX (Optional but it makes it easier on you). If you decide not to check every box, check the one that says something similar to Previous Windows Installations. Then continue, to check if it was done correctly, go to My Computer-->C:Drive-->Make sure there are no Windows.old. If there is restart your pc and check again. If its still there then go to a forum like www.thevistaforums.com and ask for additional help.
