Please Help with this issue. I hate it.

I believe this has something to do with the windows update I installed previously. I am not 100% sure I did install it before the errors started happening, but I am pretty sure. I have full administrative permissions. I was able to install a ".NET" frame work, however, it did not fix my problem.
