.NET Framework Cleanup Tool is a free program for Microsoft Windows devices to remove .Net Framework versions from PCs it is run on.
The Microsoft .net Framework is used by a wide variety of software applications. Microsoft made the decision to provide the different .net Framework versions as separate installations. This effectively means that someone who installs the Microsoft .net Framework 3.5 on a computer will automatically install the previous .net Framework versions as well for backwards compatibility, or have the functionality included in that new version of the framework.
What this means is that you will end up with several versions of the Microsoft .NET Framework installed on your computer, and that number is growing.
It can happen that the uninstallation or repair of a .net Framework installation fails which can have the effect that a new installation wont succeed either. Manually removing the leftovers to install the framework anew is a complex process.
A far better solution would be to run a cleanup tool that will remove all traces of the Microsoft .net Framework from the computer system.
Aaron Stebner's Microsoft .net Framework Cleanup Tool is that software program. The portable application scans the computer system for installed .net Framework versions.
It will display them in a list with the option to uninstall a specific .net Framework version or all of them from the computer system. The software developer points out that his application should be used as a last resort if the regular installation or uninstallation of the Microsoft .net Framework fails on the computer.
Running the program may break certain applications on the PC. Basically, any program that relies on a particular framework version that is removed during cleanup will fail to work afterwards.
The program has been designed for situations where you cannot upgrade to new framework versions, or remove old ones using built-in uninstallation options. It should not really be used as a way to remove all .NET Framework versions from a Windows PC if other means are available and working.
Update: The Microsoft .Net Framework Cleanup Tool is no longer available on Aaron Stebner's website. It is not clear at this point if the website and program have been abandoned, or if it is caused by a technical issue that will be fixed in the future. We have replaced the link, and it is now pointing to Major Geeks, a software download portal where the latest version of the program can be downloaded to the system.
Keep in mind that it supports all Microsoft .Net Framework versions from 1.0 to 3.5, and that it is compatible with all versions of Windows up to Windows 7.
Update 2: And a new page is up again. The latest version of the cleanup tool supports all existing Microsoft .Net Frameworks up to 4.7.
