But my W8 setup has a problem as IE just doesn't run. Tried in safe mode but still no-go. Also tried removing and re-adding IE but that had no effect, either. The event viewer says the offending module is ntdll.dll. Can't find anything to help with this so will have to keep looking. Would like to re-install IE10 but can't find a way of doing this.
Maybe try the "Refresh your PC" feature? It's maybe a bit brute force if you're only having trouble with IE but you can get to it by hitting windows key - enter "refresh" then under settings.
EDIT: More details of refresh and recimg:

Is it only IE you're having issues with? Or all metro apps. I had issues with metro apps and found that my version of Avast was out of date - apparently it was blocking all network access for metro apps so they would close almost immediately on trying to open them. An update of avast fixed that.
Thanks for reply, sidefx.
I only seem to have a problem with IE. I have now found that IE will run if I start W8 in safe mode with networking. That seems to imply that some program or service I run is conflicting. This is also reinforced by my problem seeming to be unique.
I have tried cutting startups out and stopping some non-windows services but nothing I have done so far has made IE run. I even cut out something essential using msconfig that stopped W8 booting! Bugger. But thank goodness for a Macrium Reflect image.
I'll just keep at it but must admit I have run out of ideas on how to better isolate the problem.
