I noticed that as well when checking task manager. Interestingly, the file versions numbers are exactly the same, despite the variances in the sizes of those files.
From: Carlos on 1 Feb 2010 21:39 Hi, Only notepad.exe in \windows\syswow64 is 32-bit. All the rest (start menu, \windows and \windows\system32) are 64-bit.

From: Charlie Russel - MVP on 2 Feb 2010 09:40 Yes, the version numbers are the same, since they're driven by the build number. -- Charlie. http://msmvps.com/blogs/russel "Tom" <noway(a)nothere.com> wrote in message news:O75Xay4oKHA.1548(a)TK2MSFTNGP02.phx.gbl... > > > "Charlie Russel - MVP" <Charlie(a)mvKILLALLSPAMMERSps.org> wrote in message > news:#hxbsRwoKHA.5508(a)TK2MSFTNGP02.phx.gbl... >> Actually, no.

From: Nobody on 2 Feb 2010 18:31 Thank you everyone. After some research, I found that I can install x64 versions in a VM hosted by a 32-Bit OS. VMWare Server is free and it does that. The free Microsoft Virtual PC doesn't support 64-Bit guest OS's. http://en.wikipedia.org/wiki/VMware_Server http://en.wikipedia.org/wiki/Microsoft_Virtual_PC

Yes, that's true. But hardly the topic you asked about. -- Charlie. http://msmvps.com/blogs/russel "Nobody" <nobody(a)nobody.com> wrote in message news:O4TWU$FpKHA.5696(a)TK2MSFTNGP04.phx.gbl... > Thank you everyone.
