The first steps I took before posting was uninstalling and reinstalling… Have rolled back to previous version of Windows now, hopefully this will solve the issue.
EDIT: Thanks for the info on the second post, I’ll keep that link handy
Quick update after doing some research. This is caused by the Windows build 1709 (check System>Settings>About). 1709 is not supported if you have N or KN version of Windows. You’ll have to roll back to version 1703 and turn off all updates and hope that Microsoft don’t force the update down your neck.
After having a lot of trouble with the idiotic update system, I’ve found the new media codecs required to fix this… They ban be found at Download Windows 10 Media Feature Pack and it’s the KB4039813 set. Finally after 6 weeks I can update the f**king thing.
