The AnalogX software writter is an extremely experienced programmer; however, he cannot know what exactly is running on your system. My suggestion is to run the program and find out what DLLs it recommends for deletion. Once you get the list, do some research on the Net to find out what each is used for. can say that and lot more....... I tried dll archive...... and it showed an extremly large number of"excess dlls"... so I went thru the list or attmepetd to go thru the list... but... considering it was well over 2000 dlls...... I didnt archive any of the list and closed the program and uninstalled it...... I am using xp and yes,it has an inumerable number of dlls,but who is to say I might not need one of them that at a later point in time that I am not using right now....that depends upon the features I am using but may decide to change later........ near every one it showed as not being used was a xp system file..... the dups ones were in the last good system file.. so it seems as a dependable and reliable tool it is questionable...dlls are called into use by .exe files and/or other dll files and one of those dlls just may be needed by another dll to function ... .. so to me..... better safe than sorry.... I dumped it and concluded it wasnt for me..... if you are looking to conserve space etc n your drive..... if were me...... I would dump the unused keyboard translations... multi language things etc and unused font files.....themes... MS games if you arent into solataire or minesweeper.... netmeeting if you dont use it and MS messenger... there are programs and methods to remove those items without trashing your windows system and cut down on cpu usage..... but as was mentioned in another post.... the win9x series are memeroy hogs and lossy memeory users..... if you have the money to play wiht and your pc can handle it go and stuff as much ram as you can afford in your pc and you will quickly see anything above 512 is lost dollars.... and xp will run effectively on a 400 pentium as good if not better than 98 does on the same machine.butit does need the ram to work but does work with 256 ok.. given that drivers for xp are available for the hardware in your machine and if you have at least a 30 gig drive you are more than good to go... look at the laptops.... HD size of most are startng at 30 or 40 gig...... this is what I have found in my messing about with this junk..... chuck...in Ok
