Well some people and I were discussing the sizes of driver files, game demoes, and what not earlier today, when I mentioned the obvious, aka Windows XP SP2 and how big it is, vs SP1... I also hinted at "anyone want to guess how big Service Pack 3 for Windows XP might be?" and that SP3 for Windows NT 4.0 was only 17.5 MB... Someone said they're disgusted that winXP with SP1 slip streamed and updated to SP2 takes 3 GBs of hard drive space... Needless to say, I remembered back to discussions about just how bloated win95 was when it took about 75 MB of hard drive space (course people had much smaller drives then)... So, figured I might create a thread to mention some of the land mark increases in system resources I remember some of these different Windows versions taking... I'll start with MS DOS 6.22 and Windows 3.1... - MS DOS 6.22 took about 5 MB of HD space, and win3.1 22 MB as I remember... - win95 was about 75 MB of HD space - Comming out around then, I seem to remember winNT 4.0 was about 110 MB of HD space wasn't it? - win98 was over 200 MB if I remember correctly - win2k and winXP taking a coupla gigs on the HD Memory wise: - DOS 6.22 and win3.1: 8 MB was more then enough and 4 MB was sufficient - win95 one really wanted at least 16 MB - win98 about 32 MB or more Same was said for NT 4 initially, though from experience my 40 MB began growing cramped around the time SP2 and SP3 came out for it... In the end, 64 MB was more like it for winNT 4 - win2k at least 256 MB recommended (though 128 MB is the minimum requirement, and runs rather slow from my prior experience) - With winXP, 256 MB might be OK, though most people I've heard recommend 512 MB these days... Along with this is the ever growing size of fix packs from one gen of Windows to another (a 260 MB SP would have been unheard of, even 2 years ago)... Anyone else want to take a further trip down memory lane, and relate their experiences wrt this?
