Seach older kernel32.dll and kernelxp.dll with Windows Explorer from your drive.
Next version exntended Kenel will make work the applications which are compiled with Visual Studio 2012 (with /MT /Mtd option).
But it is difficult that you run Vista MSPaint and etc.
And wait, what DLLs am I looking for? I do use Dependency Walker quite a bit and that's how I usually come up with what I'm looking for. Is there anyway to start getting a few Vista programs working on Windows 2000, such as Vista's MSPaint? I imagine 7's will be a little more difficult but I didn't think Vista's version was much different than 2000/XP's.
