Question about Vista

[K.I.L.E.R]

Just under "security":

Another unique x64 feature, PatchGuard, prevents malicious software from patching the Windows Vista kernel. PatchGuard, Microsoft says, works by preventing kernel-mode drivers from extending or replacing other kernel services and preventing third-party software from patching any part of the kernel.

Just what is in kernel space vs user space in Vista? This may actually prove to be bad for the user in the long run.
Microsoft slowly trying to kill open source on it's OS?
