Win XP takes at least 50% of your RAM?

[Oober_Noober]

I recently heard a claim about Windows that was a bit difficult to believe. An old-time Network Admin told me that Windows XP sequesters at least 50% of your available RAM while it is operating. So, in other words, If you have 512MB of RAM, at least 256 is taken as reserve for Windows. 1GB of available RAM would equate to 512MB claimed by Windows. 2GB eaten up if you had a total of 4GB installed, etc. etc.. This phenomena wasn't explained as being leaky or unreleased memory. Just that Windows plain and simple grabs no less than 50% of your physical RAM period. Has anyone come across reputable claims of this nature anywhere? For that matter, has anyone come accross dubious claims of this nature? I'd appreciate any leads. Even though my information comes from a reputable source and I'm certainly no fan of Windows, I’m not buying this one yet.

I'm not buying that one, either.  Here's some info on Performance fields overview pertaining to Windows Task Manager.
