Is there a possible windows upgrade for my Dell Inspiron 4000 running windows me?
Considering the fact that Windows ME is considered by many to be the worst operating system ever produced by Microsoft, I must ask, "why the heck is that computer still running this software which is, at best, an abominable piece of trash unworthy of wiping the fecal matter of the dregs of society?"
That said, there's no way it can run Windows XP as it realistically needs at least 512 MB of RAM; technically, however, the bare minimum is 64 MB of RAM. Personally, I've seen Windows XP Pro run with 256 MB of RAM, but it was, well, slower than a 60's VW "shag/peace/free love" van. Windows 2000 (Professional edition, preferably), on the other hand, requires at least 64 MB of RAM.
My recommendation? You should be able to get along by with Puppy Linux, Slackware (7.1, 8, or 8.1), FreeBSD, and/or OpenBSD.
