Don't take it personal WH4K. My post wasn't directed toward you. It was a matter of fact statement based on 1 single hour of web research. It's not at all Chicken-Littleish. It's common sense. I mentioned that during my research, I found many forum members (on many forums) that claimed they experienced no problems with the patch. On the other hand, they claim that they haven't noticed any improvements or enhancements to their Windows system either. You have just reinforced this with your own claim.
From what I've read, and I'm not an expert mind you, you cannot allow a 32 bit program to use 4GB of memory (on a 32 or 64 bit system), without altering the Windows Kernel. It's not possible, from what I dug up. Any time you mess with the Windows Kernel, you potentially open up your system to an exploit or hack. Hacks occur every day without the PC users ever knowing that it took place. That's one of the reasons why it's called hacking.
I don't see why, if you do some research yourself, you wouldn't find the same things I did on-line. It wasn't an attack on you WH4K and I'm sorry if I came across that way since I sincerely had no intention of it appearing that way.
Here, I'm not an expert and I don't do programming but, on the same website where you got your 4GB patch from, there is some explanantion involving 32 & 64 bit apps and RAM utilization. Now, from what I can decipher, he mentions "call tos" or other references that sound like he's using or fooling the Windows Kernel. That, in essence, is an alteration of the original Kernel. Maybe I'm misunderstanding this but check it out for yourself:

Mind you, I had checked other websites also, that contain content about getting 32 bit apps to use 4GB of memory.
