Or if you have spare space/drive or another machine, join the insider's program and test out Windows 10. http://www.tenforums.com/windows-10-new ... eview.html
Mind you, it is only a preview and can break on you, so do not overwrite your current OS.
The preview ends in April.
BTW, I'm still using W7 sans Aero, and prefer to get the parts together for a test machine, rather than dual boot.
You might want to go to http://www.msfn.org/board/forum/95-micr ... -products/
and see the XP/2000 and Win'98 subforums and see what their users are doing to keep their favourite Windows OS alive and kicking and secure.
Up until August of 2013 I was still fiddling with the unofficial upgrades to 2000 Pro using the 5.1 kernel and XP APIs but got tired and surrendered to 7, but 7 has a lot of backward compatibility, which I like for legacy hardware[stuff that has no 64-bit drivers] and 32 bit software. 10 promises to do the same and if you know how to implement PAE [physical address extension]
you can use more than 4gigs on 32-bit.
One guy in the 2000 forum has a six-core [broke the 2-core barrier] machine running 8gigs of system using PAE.
I think I may already posted a screen-shot here but if you go there you can see it. http://i.imgur.com/H24q6dg.jpg
