Do I need to keep all these Microsoft .Net Framework Programs?

Question by perryinjax: Do I need to keep all these Microsoft .Net Framework Programs?
I am trying to do as much housecleaning as possible on my pc and remove as many unwanted programs as possible by going into control panel then remove programs…I was getting a lot done but then I got down into the “M’s” and there are about 25 different entries or places one after another of programs titled “Microsoft .Net Framework” then there are sub headings that can be removed that are titled things like “winforms”, “Dr. Watson”, and many other names that mean nothing to me. What are these programs?
There are 3 service packs and each one includes several sub programs under the heading of the different service packs…this is where that “Dr. Watson” one is located.
I have tried to understand this question using google but it reads like greek to me. I cannot find a computer layman’s terms answer for what are these for and can I remove any or most of them?
I ESPECIALLY would like to know about this strange name of Microsoft .Net framework service pack program called “Dr. Watson”…what does it do…what is it for? in layman’s terms please…..what will happen if I remove it?
I am running Windows XP and I love it..
Thank you very much for your time as I have always gotten good information from Yahoo Answers and I enjoy this forum very much. “A world of info at my fingertips”..
I have found that the Dr. Watson is a tool that gathers debugging information or something like that…Do I need it? Do I need all of these .Net Framework programs?
I Googled Microsoft .Net Framework and got this answer;
The Microsoft .NET Framework is a software framework that can be installed on computers running Microsoft Windows operating systems. It includes a large library of coded solutions to common programming problems and a virtual machine that manages the execution of programs written specifically for the framework. The .NET Framework is a Microsoft offering and is intended to be used by most new applications created for the Windows platform.

The framework’s Base Class Library provides a large range of features including user interface, data access, database connectivity, cryptography, web application development, numeric algorithms, and network communications. The class library is used by programmers, who combine it with their own code to produce applications.

Programs written for the .NET Framework execute in a software environment that manages the program’s runtime requirements. Also part of the .NET Framework, this runtime environment is known as the Common Language Runtime (CLR). The CLR provides the appearance of an application virtual machine so that programmers need not consider the capabilities of the specific CPU that will execute the program. The CLR also provides other important services such as security, memory management, and exception handling. The class library and the CLR together constitute the .NET Framework.

Version 3.0 of the .NET Framework is included with Windows Server 2008, Windows Vista, and Windows 7. The current stable version of the framework, which is 3.5, can also be installed on Windows XP and the Windows Server 2003 family of operating systems.[2] Version 4 of the framework was released as a public beta on 20 May 2009.[3]

The .NET Framework family also includes two versions for mobile or embedded device use. A smaller version of the framework, the .NET Compact Framework, is available on Windows CE platforms, including Windows Mobile devices such as smartphones. Additionally, the .NET Micro Framework is targeted at severely resource constrained devices.

Dot NET is an odd bird in that newer versions do not include all the functions of the older ones. You may be running something that requires an older version – or not. If you uninstall a version as a test, there should be a prompt to install it again if you try to run whatever needs it. Should – not Will.

Dr. Watson is a bother. Send him packing.

There’s little to be gained by uninstalling programs if they do not start automatically. Huge new hard drives are cheap.
