Although
Windows 8 will run on both Intel and ARM chip architectures, apps will have to be recompiled for the latter; there will be no virtualisation of Intel apps to run on ARM chips, which are already used in Apple's iPad, Android tablets and HP's discontinued TouchPad.
Furthermore, applications for the ARM version of
Windows 8 will only be available through the "
Windows Store" – and only apps compiled to use its "Metro" touch interface will appear there.
