Instead, SpeeDefrag is more like a type of extension or addon to Disk Defragmenter, the included defrag program in Windows. What SpeeDefrag does is shut everything down except for Disk Defragmenter so it can be given as much system resources as possible. It functions the exact same as Disk Defragmenter but with a more successful result and faster speed. Download SpeeDefrag This review is of SpeeDefrag version 7.1. Please let me know if there's a newer version I need to review. More About SpeeDefrag SpeeDefrag works with Windows 10, Windows 8, and Windows 7 but it's really only beneficial to Windows Vista and Windows XP users (more about this at the end of my review)The program can automatically shut down or restart the computer after a defrag; you can optionally choose to restart before a defrag as well, at least prior to Windows 7If starting a defrag immediately, without restarting first, all open programs will close abruptly before defragmenting the hard drivesThe only other option in SpeeDefrag is to run the defrag regardless of whether there's only a small amount of free space remaining on the drive SpeeDefrag Pros & Cons SpeeDefrag is very simple, which means while it's easy to use it also lacks regular defragmenting features: Pros: Very easy to useDefrags internal, removable, and external drivesSmall setup file downloads quicklyUncluttered interfaceSupports defragmenting multiple drives consecutively Cons: Can't schedule defragsNo advanced optionsAttempts to install other software during setup Thoughts on SpeeDefrag We like SpeeDefrag because it can be used by anyone. You don't need to download the defragmenting program because it's already included in Windows. All you have to do is start SpeeDefrag and choose an option. Something worth noting again is that the option to restart before a defrag only works for versions of Windows before Windows 7, which means Windows 7, Windows 8, and Windows 10 are unable to restart before a defrag. Because of this, the other running programs and processes will not be terminated (a restart is required to terminate the programs). This means for Windows 7 and newer operating systems, SpeeDefrag doesn't serve a real purpose considering it's just using the built-in defragmenting program. It's really only useful for the older Windows operating systems. Obviously, you can't use SpeeDefrag for advanced features like boot time defrags, excluding files/folders from being defragged, etc., like Defragger, Smart Defrag, and other similar programs allow. However, because of its ease of use, SpeeDefrag is really nice for the casual pre-Windows-7 user. Download SpeeDefrag During setup, software you may not want on your computer tries to install with SpeeDefrag, but you can easily choose Decline or Skip to avoid them.
