Does 32-bit Windows 7 Home Premium automatically support PAE, for accessible RAM larger than 4GB? Or do I have to manually do some change?
2 Answers
No variant of 32-bit Windows 7 supports more than 4GB regardless, so whether or not PAE is enabled is irrelevant.

2@ekaj: Those do a lot more than just "enable PAE". They *replace key components of Windows itself*, changing how it behaves at a low level. – Ignacio Vazquez-Abrams Dec 26 '13 at 07:34

1@ekaj: But simply enabling PAE won't let you access more than 4GB, due to that low level behavior. – Ignacio Vazquez-Abrams Dec 26 '13 at 07:36
