Despite my use of Windows XP x86 on the PC below, I happen to run into RAM usage issues even with PAE enabled. It seems in most scenarios, XP will act like its run out of memory and some functions stop working. 64 bit has also proven to provide better performance over 32 bit. So the following reasons are why I will once again, try Windows XP x64 edition.
This is basically a log of how usable the OS will be with my software and whatnot. I have done some VM testing. Malwarebytes Premium works without the website scanner. Malwarebytes Anti Exploit works properly, which is good as it helps for security when using "unsupported" OSes. Microsoft's own Security Essentials works and gets the latest definitions. (surprising, isn't it?)
I can hope it all goes well.
