Same Updates Offered Constantly - None Are Installed.

Hi! I registered here as I'm at my wit's end with this...

I performed a fresh install of Windows 8.1 and immediately went to check updates. The main reason being that I'm unable to play certain games until my system is up to date... and because of the Windows 10 incentive.

However, I am constantly faced with this screen...


...and once those updates are chosen to install, I am told that they have installed, yet do not appear on my list of installed updates. They also reappear if I search for updates again.

Edit: I also have no other updates on my installed list..

I have manually tried patching up to these updates using the following...

..but they all return the same error. "This update is not applicable to your computer".

I am unbelievably frustrated by this and have been up all night trying every solution I can find.

Huge thanks in advance to anyone who is able to help.

Hate to bump, but I could do with some help urgently!

To start with try sfc/scannow in admin command prompt.
