    Husar, as I understand it, the newer security models (mandatory signed drivers, random memory positioning (which has a name which I forget)*, etc.) were incorporated into 64-bit Windows, and not into 32-bit. That's what I'm talking about. Also, 64-bit Windows has the same advantage as OS X; it's the minority. So lazy spyware/adware/malware writers in Bulgaria are less likely to target your platform. Something to think about.

    -edit-

    *Ah, here it is: Address space layout randomization. So obvious I would have never guessed it.

    Address space layout randomization relies on the low chance of an attacker guessing where randomly-placed areas are located; security is increased by increasing the search space. Thus, address space randomization is more effective when more entropy is present in the random offsets. Entropy is increased by either raising the amount of virtual memory area space the randomization occurs over, or reducing the period the randomization occurs over; the period is typically implemented as small as possible, so most systems must increase VMA space randomization.

    To defeat the randomization attackers must successfully guess the positions of all areas they wish to attack. For data areas such as stack and heap, where custom code or useful data can be loaded, more than one state can be attacked by using NOP slides for code or repeated copies of data; this allows an attack to succeed if the area is randomized to one of a handful of values. In contrast, code areas such as library base and main executable need to be discovered exactly. Often these areas are mixed, for example stack frames are injected onto the stack and a library is returned into.

    Well, guess I misunderstood you then, didn't know that.
    I use 64bit anyway, and about your last point, why are you recommending it to more and more people then?

    Well, it's not as though recommending it to friends and acquaintances on the Org is going to cause a huge spike in 64-bit adoption. Non-geeks don't even know the difference, and will take whatever comes loaded on the integrated-graphics boxen they get from Best Buy. I think it's safe to recommend to people who should know better.

    Tito-san, the links you provided agree only on the possibility of utilizing 4+ GB RAM for gaming purposes. The applications still are not optimized and are not looking to be in a middle-term period of time.

    So I conclude 64-bit is a bugger, rather than an innovation, for now. Nothing ain't broken and I ain't fixin' it.

    Faulty video drivers are now the annoyance of Win7, but UAC is less annoying. UAC is Paradise for those who have a brother who wants to install every program on Internet.

    64-bit Windows also allows applications to run with 3gb of Ram whilst 32-bit is capped at 2gigs. Also, the normal applications are improved in an 64-bit environment by 25% performance increase, apparently. There are a great many of reasons to adopt 64-bit.

    Wrong. Those who are not on 64-bit are the s, because they hold back innovation by using internet Explorer 6, etc. Also, let me know how the Horse and cart is getting along in Turkey, as no point getting a car if it isn't 'broken',

    It's actually capped at 4GB in 32-bit but there was some reason I forgot so you can only use about 3.5GB.

    Good point about the cars though.
    Other than that, 64bit is the way to go.

    No. Individual (as opposed to the entire system with all running processes) 32bit applications are by default capped at 2GB maximum memory. This is enforced in the header of the executable binary; and yes you can fix that yourself by setting the binary flag that tells the OS whether or not the application can (is allowed to) handle more than 2GB. CFF explorer will let you do that from a GUI.

    Are you distressed about something in your real life ?

    If one has no need to "fix it" or upgrade then you are wise to save your money. However, I just purchased a new reasonably cheap *$600* laptop with a 32-bit system to run older programs that are incompatible with my 64-bit desktop. I really had to search for a 32-bit os, most offerings are 64-bit only. Eventually you will submit.
