However, these versions lacked a built-in program that could be used to easily perform this task. Consequently, OEMs and other software developers started creating their own applications to fill this gap. </p><p>Early Windows NT versions through <a href="/wiki/Windows_NT_3.5x#Windows_NT_3.51" title="Windows NT 3.5x">NT 3.51</a> supported moving data clusters but didn't have an interface to do it. As a result, developers had to additionally create special defragmentation utilities that supported this. From all the applications released during this time, the most notable was Diskeeper, which shipped with a customized version of the NT kernel and file system drivers that could move these clusters. </p> <h3><span class="mw-headline" id="Early_years">Early years</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=3" class="mw-editsection-visualeditor" title="Edit section: Early years">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=3" title="Edit section: Early years">edit source</a><span class="mw-editsection-bracket">]</span></span></h3> <h4><span class="mw-headline" id="Windows_9x">Windows 9x</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=4" class="mw-editsection-visualeditor" title="Edit section: Windows 9x">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=4" title="Edit section: Windows 9x">edit source</a><span class="mw-editsection-bracket">]</span></span></h4> <p>In <a href="/wiki/Windows_95" title="Windows 95">Windows 95</a>, Microsoft released for the first time its own defragmenting tool for Windows, which was <i>Disk Defragmenter</i>. It could be launched on Start → Programs → Accessories → System Tools. When first opened, it opened a dialog where users could choose the drive to defragment. After that, an additional window appeared where an analysis of the drive showed the fragmented percentage, from which would depend a recommended defragmentation or not. Regardless of the result, users could defragment the drive through the "Start" button. </p><p>Once defragmentation starts, another window appears showing the task's process. However, it was also possible to see more details, such as the current stage of the defragmentation or a visual representation of the process, through the "Show Details" button. </p><p>In <a href="/wiki/Windows_98" title="Windows 98">Windows 98</a>, the drive analysis is skipped after choosing a drive, taking the user directly to the defragmentation progress window. </p><p><a href="/wiki/Windows_Me" title="Windows Me">Windows Me</a> didn't add many changes to the app, asides from the colors used for the detailed view being slightly modified. </p> <h4><span class="mw-headline" id="Windows_NT">Windows NT</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=5" class="mw-editsection-visualeditor" title="Edit section: Windows NT">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=5" title="Edit section: Windows NT">edit source</a><span class="mw-editsection-bracket">]</span></span></h4> <p>Disk Defragmenter, however, wouldn't arrive to the NT family until <a href="/wiki/Windows_2000" title="Windows 2000">Windows 2000</a>. Here, the app was hugely revamped, including the following changes that marked a significant evolution from the 9x family versions: </p> <ul><li>It is a Microsoft Management Console snap-in based on a stripped-down version of Diskeeper, whose individual launching command is <code>dfrg.msc</code>.</li> <li>A new dashboard that gets rid of the window sequence from the 9x family versions and allows to perform required tasks and view more comfortably.</li> <li>A new behavior: <ul><li>Drives are all displayed in a list view, where users can rapidly choose the one to work with.</li> <li>Users now have more control over which task they want to perform first, as buttons to manually start drive defragmentation and analysis, where the latter has been reintroduced after being removed in Windows 98, are available.</li> <li>Both defragmentation and drive analysis now generate reports showing additional information users can check, print, and save as <code>.txt</code> files.</li></ul></li> <li>A new way in which analysis and defragmentation progress are displayed: <ul><li>Under the drives list, two color graphs show the status of these tasks, getting rid of the compact view used in the 9x family.</li> <li>When these tasks are in progress, additional colors such as green, blue, and red are used instead of only turquoise and white as in the 9x family. The color legend is now shown by default at the bottom of the window instead of being hidden under a button.</li> <li>Analysis and defragmentation percentage are no longer shown in a numerical mode, and they are now limited to a progress bar at the bottom of the window.</li></ul></li></ul> <p>Despite all these changes, Windows 2000's Disk Defragmenter has some limitations: </p> <ul><li>Defragmenting NTFS volumes with cluster sizes larger than 4 kilobytes (KB) is not possible.</li> <li>It is not possible to perform fine-grained movement of uncompressed NTFS file data. Moving a single file cluster also moves the 4 KB part of the file that contains the cluster.</li> <li>Encrypted File System (EFS) encrypted files are not defragmented.</li></ul> <h3><span class="mw-headline" id="Windows_XP">Windows XP</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=6" class="mw-editsection-visualeditor" title="Edit section: Windows XP">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=6" title="Edit section: Windows XP">edit source</a><span class="mw-editsection-bracket">]</span></span></h3> <p>Updates to Disk Defragmenter made on <a href="/wiki/Windows_XP" title="Windows XP">Windows XP</a> were largely focused on improving functionality, with only one notable visual change: </p> <ul><li>Estimated disk usage before and after a drive's defragmentation is now shown instead of visual representations for analysis and defragmentation.</li> <li>Limitations present in Windows 2000 have been removed.</li> <li>The snap-in no longer relies on Windows NT Cache Manager, which prevented the defragmenter from moving pieces of a file that cross a 256KB boundary within the file.</li> <li>NTFS metadata files can now be defragmented.</li> <li>A command-line tool, <code>defrag</code>, has been added, allowing access to the snap-in tools via Command Prompt or other apps such as Task Scheduler.</li></ul> <h3><span class="mw-headline" id="Windows_Vista">Windows Vista</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=7" class="mw-editsection-visualeditor" title="Edit section: Windows Vista">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=7" title="Edit section: Windows Vista">edit source</a><span class="mw-editsection-bracket">]</span></span></h3> <p>Windows Vista introduced multiple enhancements for Disk Defragmenter once again, including these changes: </p> <ul><li>It was rebuilt into its own base rather than Management Console's, changing the launching command to <code>dfrgui.exe</code>, which at some point reflects that it's the graphical version to reduce confusions with the <code>defrag</code> command-line tool.</li> <li>Periodic defragmenting of drives can now be scheduled on the graphical version, as the <code>defrag</code> utility already had the ability since its debut in XP.</li> <li>The interface has been simplified, with the color graphs, task progress indicators, drive analysis and selection, and fragmentation data being removed entirely.</li> <li>It became part of the Windows Administrative Tools, thus popping a <a href="/wiki/User_Account_Control" title="User Account Control">User Account Control</a> prompt before launching by default.</li></ul> <p>In <a href="/wiki/Windows_Vista_build_6001.18000" title="Windows Vista build 6001.18000">Service Pack 1</a>, the ability to choose which volumes will be defragmented was reintroduced after being kept for <a href="/wiki/Windows_Server_2008" title="Windows Server 2008">its Server counterpart</a>. </p> <h3><span class="mw-headline" id="Windows_7">Windows 7</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=8" class="mw-editsection-visualeditor" title="Edit section: Windows 7">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=8" title="Edit section: Windows 7">edit source</a><span class="mw-editsection-bracket">]</span></span></h3> <p>As with Windows XP, <a href="/wiki/Windows_7" title="Windows 7">Windows 7</a>'s updates to Disk Defragmenter had a primary focus on improving the user experience: </p> <ul><li>Some classic features removed in Windows Vista have been reintroduced with additional updates: <ul><li>The drives list, which now shows the drive type and hidden partitions such as System Reserved.</li> <li>Drive analysis, which no longer launches a window to inform the status after completing.

Otherwise: <ul><li>With the app launched normally, it will reopen with the escalated privileges and the chosen task being started automatically.</li> <li>With the app launched already with administrative privileges, the prompts will be ignored.</li></ul></li></ul></li></ul> <p>Since this version, Disk Defragmenter is responsible for the TRIM command, which allows the operating system to inform solid-state drives which blocks of data aren't used and can be safely wiped internally. </p> <h3><span class="mw-headline" id="Windows_8">Windows 8</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=9" class="mw-editsection-visualeditor" title="Edit section: Windows 8">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=9" title="Edit section: Windows 8">edit source</a><span class="mw-editsection-bracket">]</span></span></h3> <p><a href="/wiki/Windows_8" title="Windows 8">Windows 8</a> had a few updates for the graphical app: </p> <ul><li>The app's naming has been changed: <ul><li>The executable name has been changed to <i>Microsoft Drive Optimizer</i>.</li> <li>The app identifier on the title bar has changed to <i>Optimize Drives</i>.</li> <li>The name used in areas such as the Start screen has been changed to <i>Defragment and Optimize Drives</i>.</li> <li>Strings that would previously have defragmentation references now say <i>optimize</i>.</li></ul></li> <li>Scheduled defragmentation has been updated and its status on the main page consolidated: <ul><li>It has been moved to the bottom of the window.</li> <li>Instead of using a full string to describe if it is enabled or not, now it only shows on or off status words.</li> <li>The next scheduled run is no longer displayed.</li> <li>Frequency on which it can be chosen to run is now only limited to the daily, weekly, or monthly paces, and the ability to choose a day and hour has been removed.</li></ul></li></ul> <h3><span class="mw-headline" id="Windows_10">Windows 10</span><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/index.php?title=Drive_Optimizer&veaction=edit&section=10" class="mw-editsection-visualeditor" title="Edit section: Windows 10">edit</a><span class="mw-editsection-divider"> | </span><a href="/index.php?title=Drive_Optimizer&action=edit&section=10" title="Edit section: Windows 10">edit source</a><span class="mw-editsection-bracket">]</span></span></h3> <p><a href="/wiki/Windows_10" title="Windows 10">Windows 10</a>'s initial release had an untouched Drive Optimizer from the 8 family.
