WSUS clear out updates for un-needed OS

[SM17]

Hi,

 

Have set up WSUS on my SCCM box.

 

I have accidentally clicked Windows 8 in the Products to download updates for and now have 433 Updates for Win8.

 

I don't have any Windows 8 machines though, just 8.1.

 

How do i remove them in SCCM please?

 

I'm only used to managing WSUS through the WSUS console - where id decline any updates i didn't want and then run the cleanup wizard.

 

I don't see any option to lose them in SCCM though.

 

Thanks
