Does any other version apart from 10 work with Vista?

Ultimate Defrag may be better for you with Vista. I was also waiting for O&O v10 for Vista use but with the changes made, I can not recommend it.
What I do not like about Ultimate Defrag is there are too many variables for the typical user. Yes, it is a powerful program but thats like putting a Piper Cub pilot into a 747 and telling them to fly. Moving stuff all over a hard drive is not needed and is overkill simply because, the user should ALWAYS adhere to the following RULES of hard drive optimizing...
1. Never partition a hard drive other than 'storage' drives for backup software and media files
2. Never fill a hard drive more than 60-70% absolute max, to do so significantly reduces performance. Optimal is 50% or less
3. Only install programs to a Windows OS and try to keep items such as media, music and others on another drive.
I always move the "My Documents" folder to another drive using the move feature in Windows. This allows the system to find the folder just as if it was installed on the same drive as Windows but if anything ever goes wrong, my documents and other files in that folder are always safe. I can wipe out Windows and never worry about loss of docs and the huge amonut of information in that folder never fills up the OS drive. I also move My Favorites, My Music, My Pictures and keep a copy of my CLEAN and organized START MENU folder, which has my organized programs menu of installed programs ready for a reinstall so I never have to organize it again.
I never go looking for things on my system because they are all in perfect order...

4. You can use a separate drive for MSFS or other games as long as you maintain the same rules for performance. Never partition such a drive and never put anything on it other than the titles you want to run and keep it 50% free, but you can push that to 70.
If the above is followed, there is no reason to move and jumble files around a hard drive like Ultimate Defrag allows. All you need in a defrag are 6 things..
1. All parts of a file will be located and placed back together
2. All files will have the free cluster space removed between them
3. All files will be placed in a NAME order, creating a sequential access file system
4. The MFT catalog will be defragmented and the cluster record will be placed in numerical running order
5. The page file, something that if the systm has enough memory wil very RARELY be used, should go after the data and the MFT
6. All files needed to boot the computer will be located and moved to the FIRST sector of the hard disk and also placed in the BOOT order they were called up in the layout.ini file.
Thats it. This business of moving program exe's to the beginning of the disk and zip's and other parts of a software install to the end is rubbish. It is better to have every FOLDER AND FILE in a OS/software install in perfect alphanumerical order.
Ultimate Defrag claims its best to put the unused Windows files at the end of the disk... Did they also mention that the folder WINDOWS is the LAST FOLDER LISTED in a hard drive root directory? AND Did they also mention, if you do a NAME defrag the letter W is at the END of the alphabet?? Which means in a NAME defrag WINDOWS and all the OS files not needed at the beginning of the disk, go to the END. They make it sound like their software does something amazing when in fact they copied O&O Defrag's practice that has been in use for years.
Ultimate defrag does a sales pitch that in many ways is bull. O&O Defrag v8 or 8.5 does the job just fine, clean and simple and without the bull story.
There is nothing wrong with ultimate defrag, it will work, but if you dont know what you are doing it offers features kiddies should not be touching.
You just need to follow the rules of hard drive/data use and do a COMPLETE\NAME defrag of the file system, its that simple.
