I am having issues removing Microsoft.Net. I recently upgraded to Windows 8 Pro from Windows 7 and by doing so a few of my files have been changed and/or needed upgrading. I currently have Microsoft.NET 4 Framework installed and I'm trying to remove it. Every time I go to uninstall, I get an error saying "Already apart of operating System, but is currently turned off. You must turn it on via Control Panel". I went to my Control Panel to turn it on, which can be shown:

This is really frustrating because I have no idea how to fix this issue, and I do not have my Windows 7 disk anymore to downgrade. Can anyone please help me fix this?

If you upgraded from Windows 7 to Windows 8 then you don't have .NET Framework 4.0 installed you have .NET Framework 4.5 installed since its an in-place replacement. So I am going go ahead and remove the Windows 7 tag. The .NET Framework 4.5 CANNOT be removed if your running Windows 8. Just like you CANNOT remove .NET 3.5 if your running Windows 7. –  Ramhound Jan 3 '13 at 12:31

You need to turn it on fully, the fact it's a square box suggests it's only partly on. Expand the tree to turn on all/turn off all.
