first of all, thank blackwingcat, I've been reading a lot about all of your work, in your blog, etc. and everything about W2K and I think I must congratulate you for the moment I have not tried your kernel extension, but I'll try, but exists a lot of information about XP api ported to 2k and I haven't found a good guide explaining what updates I can install and what not and an order to install. Another thing confused is about another API for Windows 2000 XP made by .. OldBoy2k?? in oldcigaret.. which is better? and exists other here: http://www7.atwiki.jp/win2000/pages/17.html ? am I right? on the other hand: I would like to know why you prefer to use your Windows 2000 machines instead of Windows XP? I guess the answer to my question related anger performance windows, so I want to ask if you have used MicroXP? And finally I would like to know if with Windows2000 I can get more FPS in games than in XP? What advantage is there in using windows 2000? I am a computer addict user since Windows 3.1, I understand that since Windows 2000 (or maybe 9x) the computer's response time has probably changed by the large amount of wasted resources or lack of optimization lot of thanks!
