Windows Security Updates

[Gloria E]

I noticed that my updates included Microsoft .NET Framework 3.5.1 and .NET Framework 4. Is it necessary to have two versions of .NET Framework? Do I need 'Framework at all?

Today, I installed the latest updates (for last week) and the two above were included.

I'm not an expert on the topic, Gloria, but I'm pretty sure it's been said here in The Lounge that there are an ever growing number of applications and/or web sites that depend on .NET Framework. I suppose you wouldn't need it if you were willing to bypass any places that do use it.

As for multiple versions, I think the reason for leaving the older is in case a using site or program isn't up to snuff with the latest.

One of the others may say all this more succinctly than I can.

There are about 4 different versions of the .NET Framework: 2.0, 3.0, 3.5 and 4. Some applications need one version, some another. These versions coexist peacefully.
Windows 7 itself needs at least one of these versions.
In theory, you could uninstall one or more of these versions to see what, if anything, breaks. But in practice it's easier to let them be - you never know when you might need them.

Do I need 'Framework at all?

The question is a bit academic with Windows 7, compared to older OSs, since it's part of it.
See this thread, of yours, and the advise from fellow Loungers. You have also asked it here.

O my goodness, I've asked the same question more than once. When will I get it through my head that the answer is to leave well enough alone. Sorry about that, I'll do my best to remember.
