I attempted to download and Install Microsoft .NET Frameworks while working with Dell support to download some drivers. The download and installation failed. I was unable to complete this task with Dell on this system. Can I now uninstall what was downloaded and partially installed. Microsoft .NET Framework 2.0 Service Pack 2, Microsoft .NET Framework 3.0 Service Pack 2, and Microsoft .NET Framework 3.5 SP1 show in my programs listing. What is Microsoft .NET Framework and do I need it?1 person needs an answerI do too

Its used by various Programs, and any updates will be installed with Critical Update.If the download / installation failed the only files remaining will be those in your temp folder.Perhaps you ought to run MSUpdate and see what critical updates are offered
