Seems to speed up computers a bit. Does a thorough job. Gives you many defragmenting options. Wipes out system restore points on Windows 7. Takes its' sweet time. I use this on two computers, an old xp and new 7 machine. It works fine on the xp pc, defragging even the system restore partition that is usually un-defragmentable, albeit taking hours to complete. It seems to have slightly sped up both machines beyond their speeds while using another free defragmenter. The biggest issue I have with mydefrag, is that it wipes out all of my restore points... every time. I had read about this problem before I installed it, and yes, it is true, even if I choose only to defragment only the c partition, and nothing else. I simply make sure my computer is clean and working properly before I defrag.
