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 https://www.microsoft.com/en-us/software-download/mediafeaturepack and it’s the KB4039813 set. Finally after 6 weeks I can update the f**king thing.
