Hello Fsyoza. It is time to re-register the DLL files connected with Windows Update.
Please download the attached archive and extract it. If you are unsure on how to open the archive, use the instructions from here and continue. After you have extracted the archive, you should obtain a file labeled Fix Windows Update.bat. Double-click on the file and a window will pop-up for a brief period of time and close automatically. Don't panic; this is normal. After the process is complete, please restart your computer and try to install the updates again.
Let us know how it goes though. Good Luck. :)
