Characterisation of WOW

I wonder if WOW is a kind of virtualization or emulation or perhaps it works like WINE? Would be nice if someone could clarify that. -- John Ericson 18:52, 10 September 2006 (UTC)

WOW is emulation non non-x86 NT systems (via NTVDM). On x86, it uses the Virtual 8086 mode of the CPU. This mode is unaccessible from x86-64 long mode, but modern systems are sufficiently fast enough that there is no reason that classic non-x86 NTVDM emulation could not be used.

Long filename

It should be noted that long filenames are not shortened in any way for 16-bit processes. Instead, NTFS stores a short filename for each long filename. The only difference from FAT12/16/32 with Long File Names is that the short 8.3 filename is optional. If a file entry does not contain an 8.3 short filename, then DOS and Windows 3.1 applications cannot access it. Segin (talk) 15:01, 12 July 2010 (UTC)

WoW or WOW?

Is it really WOW? Why not WoW as in WoW64 (besides the clash with World of Warcraft)? It seems inconsistent. --Mortense (talk) 12:25, 30 December 2016 (UTC)

Hello, Mortense. I checked the sources at both articles. It seems WoW64 should be WOW64 according to the sources.

Best regards,

WOW on Win9x?

Windows 98 comes with a file called "wow32.dll", which would appear to be WOW on win9x. In the article, though, it only says "[Win9x] could run 16-bit software natively without requiring any special emulation". More information about WOW on win9x would be nice.
