When I first got my SP3 (first day in UK) I think it did a system update immediately... couldn't swear to it though. Anyway, I set about installing all the applications I need, all of which are desktop apps. I then ventured to the Windows store to install some games, and settled on a 3D chess game. I also installed a magazine application for cyclist (this one). I took a look at Flipboard too, which was already installed. They worked fine, I was chuffed to bits. One system update later these three apps failed to work. Basically they stopped opening after their initial load screen. An error is recorded in the windows error log: I think the key bit is this - and it's the same for all the apps: Faulting module path: C:\windows\SYSTEM32\combase.dll In fact other MUI apps don't work such as the fresh paint one. It has the same error in the logs. Other apps, IE, the weather app, do work. I'm all up to date with windows update. Does anyone have similar problems or hopefully ways to resolve this?
