I have been having this issue now for a few month with every O/S; a part from Windows 10, where is just keeps on searching for updates and using all of the memory and gets no where.
I have tried installing a clean O/S, and different version: Home, Pro, Ultimate and it's still happening.
I have recently got an old laptop out and tested it on there: Windows Vista, and it's the same.
I thought it was the ISP, so I've restored the router to default, and the same happens. I called Virgin Media and they said 'does it happen on windows 10'? I replied 'NO'. They said upgrade then to Windows 10. I don't want to. I like Windows 7...or did.
Does anyone has any ideas?
I've tried stopping and starting it on services and cmd wsus.
