X86 virtualization

I’m excited about the news today from Microsoft announcing that the next version of Windows will support System on a Chip architectures from Intel, AMD, and ARM. We announced that the next version of Windows will support System on a Chip (SoC) architectures including ARM-based systems from partners NVIDIA, Qualcomm, and Texas Instruments.  And, on the x86 architecture, Intel and AMD continue their work on low-power SoC designs that fully support Windows, including support for x86 applications.

Happy New Year everyone! At CES 2011 in Las Vegas, we hosted a press conference announcing that the next version of Windows will support System on a Chip architectures from Intel, AMD, and ARM. We announced that the next version of Windows will support System on a Chip (SoC) architectures including ARM-based systems from partners NVIDIA, Qualcomm, and Texas Instruments.  On the x86 architecture, Intel and AMD continue their work on low-power SoC designs that fully support Windows, including support for x86 applications.

We’re announcing an update to Windows XP Mode today that will make it a more accessible to PCs in small and midsize businesses who want to migrate to Windows 7 Professional but have applications that still require Windows XP. Windows XP Mode will no longer require hardware virtualization technology to run. This change makes it extremely easy for businesses to use Windows XP Mode to address any application incompatibility roadblocks they might have in migrating to Windows 7.

Earlier today, Core Security Technologies issued a security advisory for our Virtual PC (VPC) software. The advisory calls out a proof of concept where the virtual machine monitor allows memory pages above the 2GB level to be read from or written to by user-space programs running within a guest operating system. The advisory explicitly calls into question the effectiveness of many of the security hardening features of Windows, including DEP, SafeSEH, and ASLR.  Folks are already starting to ask questions about this advisory, so I thought it would be best to answer them here.
