Solved Haunted by opaque window on new PC

[mark99k]

Other than Office I've installed next to nothing on this extremely new PC, but at random times ALT+TAB will display one icon more than there are visibly open programs. Further, if I choose that icon from the switcher, a small (maybe 300px) square "window" is activated, but it's completely featureless & opaque. It closes with ALT+F4 like anything else, but that's the only response I can get from it -- right-clicking inside it gives no response. The screenshot attached shows the icon displayed in the task switcher. Can anyone identify it? Virus scan comes up clean.

Try running an sfc/scannow command in an elevated command prompt and see if it helps.

Hm, good idea. But it says no integrity violations.

@Mark:

Are you certain that this PC is brand new and came out of a factory sealed box? I'd be interested to know if this unit was possibly a return of somekind.

I would call the manufacturer and speak to them about it. Maybe you can return it for a replacement.

Could you start Windows in Safe Mode and see if the problem persists? A 3rd party app might be interfering with it.

Could you also run the sfc/scannow command twice more with a restart after each? It might have missed some files the first time round and it doesn't hurt to try it again.

What anti-virus did you run? Could you try running a full system scan with Malwarebytes?

Hello mark99k

Could you please check in msconfig/start-up and see if anything that is starting up with windows has that icon - http://www.sevenforums.com/tutorials/1401-startup-programs-change.html Do you have a fingerprint scanner as it looks very similar to one I have for that.
Also could you fill out your system specs to help us help you - http://www.sevenforums.com/tutorials/180324-system-info-see-your-system-specs.html

UPDATE: It's the Dell Backup and Recovery Manager, according to its [hidden] icon in the System Tray. Why it insists on creating that opaque window or even announce itself in the Task Switcher is still a mystery.

You could try unchecking that program in msconfig/startup to prevent it starting with windows, see if that helps.

Oh yes, sorry - forgot to mention, I did exactly that and it's gone.
