Copy of Windows 7 Ultimate isn't showing updates

I've recently built a computer with the aid of my friend with Windows 7 Ultimate (64 bit) installed back in mid August. During this 2 month period I've noticed that Windows hasn't informed be about any updates and whenever I go to check for updates, it says to restart the computer. Another thing to note is that my copy of Windows 7 was bought back in 2011 and has not been used since then.

Asides from this, I also got a notification regarding my copy of Windows 7 isn't genuine even though I bought it.

Any help would be appreciated. Thanks :)

The COA ticket on the case of the installation disc reads the following:

"BTS - 3243174 - MSIN
Win Ult 7 English ROW DVD"

Asides from that here's the diagnostics from the .exe you provided:
