Hi Boggin
I still did not run those commands; I had run some that seemed alike, before, and they did not produce any effect.
I tried to install some updates manually from Microsoft Download Center, then a box came out: Windows Update Auto Installer, and a progression bar showing a never ending movement... It seems that even trying it manually, Windows Update remains in charge... nothing was installed, except Microsoft Silverlight, for which my browser (I. E. 9) was saying it was not updated and was allowing to do so; so, now there is in Programms a new one installed, Microsoft Silverlight with today's date, but I had it already (not visible in Programms).
Other than this, it is the same situation...
