thank you so much for the feeback,

for the MSR , usually they post what you need to make it run
not what you need to use in the real world

128 MB minimum (256 MB recommended)
400 MHz or faster CPU minimum (500 MHz recommended)

that will install VMWare , but i don't think i can actually use winxp with it
that is why i am asking

so,i think i will update to 2GB RAM
have a clean winxp install with nothing at startup (even without some toshiba defaults)
Then i think i will have VMWare installed

i am not sure i will put antivirus on the basic xp
i am sure i won't make it run with vmware as it will eat ressources
maybe, i will have it installed, and from time to time i will run a scan
(i don't think i will be needing it)

I am searching now on different versions of vmware
if i can make a software interconnnect between virtual machines
for example i don't want to install and keep updating softwares: truecrypt/adobereader/opera/firefox on different machines
