Just tried the INI on XP - the 2001 original XP which I then slipstreamed SP2 and Hotfixes into, then ran your INI and it has ended up 103Mb not 57Mb I tried 4 builds - one leaving in what I normally would, and it ended up 157Mb, this is very strange since I know it should be smaller! So I gradually took stuff out (which, heh, is putting stuff back into the ini, no... so I just rarred the old ini and used a more complete one each time - down to the original file which gave a 103Mb build on the entire untouched INI. Now, I know I took a lot of things out, like battery (80kb) that could be left in for what this is worth (80kb) and the amount of people who complain about it not working on a laptop jeeeez - is it me or is it really just that "Battery" bit which gives total laptop support? So long as its not IBM Thinkpad... This is what I cant understand - it can be stripped to 57Mb I am not disputing that, maybe, but why not just leave something like Battery in since it is just 80kb and allows laptop support?! The reg tweaks... one takes arrows off shortcuts (which some programs need to identify it as a shortcut) and one removes the shortcut prefix... that is crazy, you end up not knowing if the folder is local or what the hell it is! I have heard of removing the shortcut to prefix, or the arrows, but not both in one go! How do the reg tweaks save any space? I guess some do to a degree but, most are cosmetic, which does improve performance a great deal for some changes (disabling services we did not/do not/will not EVER use) This is a great concept, a truly microscopic Windows and the best thing is... its XP
