windows 8 Post Win7 Pro - Win8 Pro upgrade - Device Manager hangs at scan

[News Bot]

Win8 Pro system whereby Device Manager (DM) hangs after invoking a scan for new hardware.  The scan never completes and I cannot close Device Manager except by force via Task Manager.

This system was in-place upgraded from Win7-Win8 a couple of days ago and after the Win8 desktop first came up I checked Device Manager and was able to perform the scan.  The missing/incorrect driver I had to deal with was for my wireless device. 

Windows Update did not install a driver for it when invoked via the drivers tab on the device object.

After downloading the latest driver from Acer for this laptop I attempted to install it; however, that didn't go so smooth.  The installer hung at the very end and so nothing actually completed.  I had to shut down/restart the system and now am

in the state whereby the Device Manager now hangs too.

Ideas?  ...while I'm waiting for replies I'm going to try a System Restore point if any exists and see if I can get back to where at least the DM can scan for new hardware.
