Drive Icons not showing in Dierctory Opus

I turned on my computer this morning to find that all my drive icons have disappeared. I have no idea how to get them back

Try fully exiting Opus and then clearing your shell icon cache.

I have tried that aready without success.

Do the icons show up in Windows Explorer?

No they don't.

If the icons don't show in Explorer either then it's not an Opus problem and about all we can suggest is try rebooting and clearing your icon cache again.

Did you install any other software recently that may have affected the icons?

The only thing I have installed recently is .NET Framework 4 plus loads of updates. Could that be the problem?

Seems unlikely.

After looking around I followed the instructions here. A little bit annoying as I had to do it for very drive. But at least they are back.
