I recently discovered that there were so many versions of the above
installed on my machine: 1.1; 2.0 SP1; 3.0 SP1 and 3.5. Is it really
necessary to keep them all or could I dispense with the first thre and
remain with only Microsoft.net Framework 3.5

Some (not many) programs might need a certain version.

You can read up on it, but I have the same thing and just leave it
alone.

Yes, if you run programs that need those versions.

No. One does not replace the others.

Actually, I believe the 3.x framework can replace the 2.0 framework since
the underlying assemblies for the 3.x framework belong to the 2.0 framework.
I recently installed the 3.5 framework (I had not yet installed the 3.0
framework) and looking in the installation folders
(C:\WINDOWS\Microsoft.NET\Framework\v3.0 and
C:\WINDOWS\Microsoft.NET\Framework\v3.5) I see that they contain no
assemblies from the 2.0 framework. Those assemblies remain in the
C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727 folder.

There's a nice image for the 3.5 framework architecture. Note the 2.0
underlying framework.

As long as you're patched, you should be able to safely keep the 1.x
frameworks (and 2, 3, 3.5) on your system without any issues. There were a
few security fixes (in the 1.x frameworks) so do make sure you stay up to
date with your system patches and service packs.
