In Windows Vista, process of defragmentation would run silently in the background. However, this process is a bit different from that of Windows XP and under Windows Vista the graphical interface is not provided to show the defragmentation progress as in Windows XP.

If you want the graphical interface, a third party defragmentation programs shall be installed.
 
Here below are some defragmentation programs and choose one to use.

Auslogics Disk Defrag is a tool that supports NTFS, FAT 32 and FAT 16 volumes. You can set the schedule for defragmentation.
 
Then automatic defragmentation will be run even when the system in your computer is idle. Also it has a customized advanced options to choose which files shall be defragmented.
 
UltraDefrag is an open source tool that you can use the kernel based driver to run defragmenting very fast. It also offers a simple graphic user interface as well as cluster map display and command line interface. You also can set a schedule for defragmentation.
 
Puran Defrag  is very convenient to use. It offers free space optimization, background (low priority) operation, intelligent directory optimization, automatic defragmentation and boot-time defragmentation.
 
You could also set the schedule for defragmentation. Other features include automatic shutdown or restart after defragmentation and arrange defragmentation of individual files under Windows.
 
You could download the free version which is identical to the standard version.  However this shareware is restricted to non-commercial and private use.
 
Smart Defrag automatically prevents the hard drive space from being overly defragment and defragment might cause a slower disk performance. It continues to run in the background even when the system is idle.
 
Further basic maintenance is not required. There are also some manual options e.g. scheduled defragmentation and optimization of the file system.

Just for your information, the default defrag tool in windows Vista only defragment files smaller than 64 MB. If you want to defrag a HDD partition which probably is higher than 64 MB then we will be using the command line defrag tool of windows Vista.
 
First run Command Prompt as an administrator, and type the following command in command prompt.
 
Defrag c: -v -w
 
Where:
 
  • c: = The drive to be defrag, change it if you want to defrag other drive.
  • -v = To display report after defrag.
  • -w = Do a full defragmentation.

Have you check if you are using the computer as a Guest Account that's why you cannot start Defragment utility. That's why you will need permission to access it. Try to use the Administrator account to start the defragmentation.

And then restart your computer and then when you reached the Welcome Screen, press and hold the Ctrl+Alt keys and then press the Del key twice.

It will launch the username and password box. type Administrator on the username field and then press the Enter key. You will be logged in as the Administrator. And then try running the Defragment utility again.
