(For Windows the latter is actually true, insofar as 64 bit processes can't load 32 bit DLLs and 32 bit programs are actually run in a minimal hypervisor on Win10. This was less well developed when Win7 was current; the hypervisor only ran WinXP iirc, not 32 bit W7.) -- brandon s allbery kf8nh sine nomine associates [email protected] [email protected] unix, openafs, kerberos, infrastructure, xmonad http://sinenomine.net
