Source? AFAIK EPM is a 64bit only feature. In theory you're absolutely right, I'm just not convinced it matters in practice. AFAIK (although I'm not an expert) the security features provided by EPM are identical on 32 and 64 bit systems except for one single component. It's my understanding that EPM is simply a collection of security measures specifically for IE. Prior to Windows 8 it would have been, but Windows 8 has very much improved ASLR on 32bit Systems. A 64bit system can be more obscure (the attacker must wade through more muck before getting to the good stuff), but IMHO that's nothing that will stop a well educated hacker, so I don't think this is really worth listing as an advantage of 64bit Windows. At heart, ASLR is an example of security through obscurity, which in security circles isn't considered real security at all. IMHO ASLR is a protection mechanism that serves primarily as a script-kiddie deterrent (it requires a lot more knowledge and time to write an exploit that can successfully attack an ASLR protected process) and is relevant as a countermeasure only when a system was already successfully infected (I tend to prefer security measures that prevent infection in the first place). Enhanced Protected Mode - IEBlog - Site Home - MSDN BlogsThank you for the clarification! The RAM savings on 32bit systems will occasionally lead to far more tangible benefits.ĪSLR is better - larger address space. At least for the average web/office/mail user it's a completely irrelevant (theoretical without practical implications) argument. Some may make the argument that 64bit systems have performance advantages, but ask them to show a study/benchmark demonstrating this on the PC and they will come up empty handed. The 64bit OS only makes sense with 4GB or more. That's also why every new device with 2GB of RAM has the 32bit OS pre-installed. Lowering RAM consumption is a particularly good thing if you've got only 2GB of RAM to work with, as that will allow you to do more before your device runs low on RAM and starts swapping memory pages to your page file. That's why you should prefer the 32bit version, as this will lower your RAM usage by roughly 10%. Compared to their 32bit counterparts, 64bit OSes and software require more RAM to do the exact same thing.
