Windows Vista Recovery Disk

I have a HP Pavilion m8167c TVPC with Intel Quad Core @ 2.4ghz and Vista Home Premium 32 bit OS. How can I increase the capacity on the Recovery Disk as it only has 9% remaining but should have at least 15%? Any help would be deeply appreciated!

 

"It must be at least 15% or one will continualy receive a message that a drive is full and will slow down your computer. Recovery Disk, usually the D drive will be RED when you check your disks, defrag your disk and when you run tune up-all results will tell you that Disk D is only at whatever and requires your attention! "

 

You haven't been saving files to the Recovery Partition? If you have remove them.

 

Have back-ups been saved to the recovery drive?
