Thank you Hazenut for your response. I thought of that also, but I hesitated in doing that. I installed it on another computer and actually looked at the programs structure, in which now I see Defraggler is only three files in that directory itself. I know there are other files it placed throughout the windows and system directories also, but I'm just not sure if I can safely just delete these three files in the c:\program files\defraggler directory and be ok.
Notice the computer with the problems is running XP PRO[sP2]. The second computer is running XP HOME[sP2], both with administrative privileges. I might be making a mountain out of a mole hill here, but after looking at the properties of these files (defraggler.exe, df.exe, and uninst.exe), Defraggler appears to do a lot more with the installation on XP PRO.
For example, file properties with XP Home show the generic stuff, tabs General, Versions, Compatibility and Summary. XP PRO is much more extensive with tabs for General, Program, Font, Compatibility, Screen, Misc and Memory for memory allocations.
So the questions are, can it be as simply as just deleting these three files?
Will Defarggler reinstall after that with the others files it leaves in other places, including the registry changes?
And, will I not lose anything else from my computer in doing this? Or, am I over thinking this?
Why doesn't the debugging script work and what the hell did CCleaner do to Defraggler?
Or, could I simply do a 'system restore' to a early date before the installation?
Thank you, again (help!)
