Tim, about the shutting down programs, If you look carefully Kutter mentioned about "95/98/me" only. And in those you can actually shut everything except explorer. :-) However, it's not the case for W2K or XP ... they need to keep so many files in memory for their 'smartass' kernel. And agree with MightyPete. However, whether the originator of this post shows up or not, I would love to know a proper solution for it. Pete, thanks for the link, lots of unrecognized files are now clear. But, my case the explorer itself gets VERY busy and takes up 100% of CPU. And I might have just opend Vue or just clicked on it or sometimes some other programs. It's definitely not Vue I'm certain of that. But hoping you guys might have some solutions. My case, it's XP in P4 1.4GHz 640 RDRam 64 MB video memory (AGP2).
