The latest version of the program can be obtained at SourceForge. Both installers and portable packages are available. The latter require no installation, thus can be used directly from USB sticks. They include all the components except of the boot time defragmenter.

All the binaries are available for three processor architectures: x86, AMD64 and IA64. The first one is for 32-bit editions of Windows. The next one is for 64-bit editions. The last one is for Intel Itanium driven computers running Itanium editions of Windows.

For example, if you need UltraDefrag for Windows XP 32-bit edition download the x86 installer. If you need it for Windows 7 64-bit edition, download the AMD64 installer regardless of the processor you have.

You must be an administrator to install and run UltraDefrag.

The installation process is pretty straightforward, only one thing deserves to be mentioned. During startup the program sends a bit of usage statistics to the Google Analytics service. It helps us to understand better your needs. However, you may turn this feature off during the installation.

Silent mode

UltraDefrag can be installed silently (without graphical dialogs) using additional command line switches:

Install the program silently.
Install all the components.
Install the console and boot time interfaces only.
Install or remove the graphical interface.
Install or remove the console interface.
Install or remove the boot time interface.
Install or remove this handbook.
Install or remove the Explorer's context menu handler.
Install or remove all the shortcut icons.
Install or remove the start menu icon.
Install or remove the desktop icon.
Install or remove the quick launch icon.
Enable or disable the usage tracking mentioned above.
/D={Installation Folder}
Set the installation folder. It must be the last parameter used in the command line and must not contain any quotes, even if the path contains spaces. Only absolute paths are supported. The destination folder must be empty or contain a previous UltraDefrag installation.
The shortcut icons force installation of the graphical interface they depend on.
The same way the context menu handler forces installation of the console interface.

The following samples illustrate use of the command line switches:

:: install everything except of desktop and quick launch icons
ultradefrag-7.0.0.bin.i386.exe /S /FULL=1 /ICONS=0 /STARTMENUICON=1
:: install the console and boot time interfaces only along with this handbook
ultradefrag-7.0.0.bin.i386.exe /S /MICRO=1 /HELP=1
:: remove the boot time interface from the previous installation
ultradefrag-7.0.0.bin.i386.exe /S /BOOT=0
:: change the installation folder
ultradefrag-7.0.0.bin.i386.exe /S /D=H:\Software\UltraDefrag
:: uninstall the program silently
%UD_INSTALL_DIR%\uninstall.exe /S

For troubleshooting omit the /S switch and check out dialogs to ensure that the installation parameters are adjusted properly. In case of errors check out the following file as well: %TMP%\UltraDefrag_Install.log
