I have 4GB of memory on my Vista Home Premium system and I see that
virtual memory is still being used - would I be safe in disabling
virtual memory? I know when I ran Windows XP I had no problems
disabling the virtual memory when I had just 2GB.
Disabling it in either XP or Vista is a very bad idea. Note two
things:
1. There is no possible benefit to disabling it. If it's not needed,
it won't be used.
2. Windows preallocates memory to the Page File in anticipation of
possibly needing to use it (that's almost certainly what you are
seeing reported, not what is actually being used). If you disable the
Page File, those allocations get made to real memory instead, and the
result is that you can never use that part of your RAM.
You may have no problems disabling it in XP, but that was because 2GB
of RAM was so much more than you probably needed that the amount doing
so locked out didn't hurt you. And disabling it didn't help you in any
way.
