Hello again, my name is Chris, anyway, I was thinking before of running Windows 2000, but the one thing I don't like about it, is that it will not be able to use all my ram, which is disappointment to me as I use a video editor alot for personal projects, not only that I cannot figure out how to even install Google Chrome on W2k, seems complicated as I must be doing something wrong also Windows 2000 kept crashing on me from just using firefox and downloading a file too rebooting explorer for no reason which was frustrating, I was testing W2k in a Virtual Machine to see what I would have to do, and running any other system such as Windows NT would still be problematic. so I though I should stay with running a x64 operating System as I already have over 11GB of RAM, 2x TB Drives and a processor that is not supported on such older systems. I currently use Windows 8.1 Core, but I was wondering if something like XP x64 or Server 2003 x64 was any more faster then what I am running. so I tested Microsoft Windows XP Professional x64 in a Virtual machine, I noticed that the installation was very fast, and even logging on to the desktop was quick. though I remember when I used it years ago, I had some trouble with applications though I cannot remember what didn't work, anyway would this be a good idea or should I just forget it and stay with Microsoft Windows 8.1 Core.
