NET software is used by MS (and other programmers) to enable
uploading. We can uninstal all NET software in confidence that,
if some future MS upload requires it, we will be directed to the
appropriate MS page to reinstal. But this also means that, if
we uninstal NET, and some non-MS app later requires NET to upload,
we may not be conveniently pointed where to go to get it.

Frankly, I 'thought' they were all installed by Windows Update. But I
have since removed a number of applications that might (might) have
claimed to need it in the past.

Not sure what Peter is referring to. If you installed the Microsoft
..NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update
from Windows Update (which was supplied via WU a little over a year
ago), it installed an update for .NET Framework 2.0, and ALSO installed
..NET Framework 3.5 whether you needed it or not.

As far as I know, that update installed .NET Framework 3.5 even if you
had no software installed that used it.

Have a look here:

Framework 3.5 Family Update

It depends on whether you installed all of them manually or did some
third party applications install redistributable versions on your system?

If you installed them yourself then probably you don't need them and so
uninstall them; If some third party applications installed them then
you do need them (not all but a specific version).

Very soon, you will be bombarded with version 4. I have downloaded and
installed on my system because I have started using VS 2010 for my work.

Assuming "version 4" is a good thing, wouldn't it be sensible to remove
1-3.5 of .NET first, then install NET4?
