One of the biggest culprits is the System Restore files. SR can use up to
15% of the whole drive or 30% of the free space on the drive. These are all
hidden system files.
You can delete all but the latest SR points using the Disk Cleanup utility.
Go to Start/All Programs/Accessories/System Tools and click on Disk Cleanup.
Select the Files from All Users option.
Select the drive where Vista is installed.
Select all of the files you wish to delete.
Select the More Options Tab.
In the System Restore and Shadow Copies section, Select the Clean up Button.
Select Delete in the pop up dialog.
Click the Clean Up Tab.
You can control the amount of space used for SR. Go to the following website
for the instructions.
