Desktop I7-4790 - 16g memory - W10 latest incarnation - Start/Run/cmd.exe, opens then immediately closes. Sometimes you get a flash of the whole window but mostly just a flash of the min/max/exit buttons. Can anyone suggest a fix?
Fixes I've tried : Tried RKill, Malwarebytes, Avast freebie runs permanently, everything up to date.
Background : It first happened 3 weeks ago just after windows did its latest massive update, so I formatted the windows drive (SSD) and reinstalled w10. Command box worked fine until windows did the same update again - back to square 1. Is this MS telling us to convert to Powershell????
I've put cmd.exe on a stick from a different machine not affected, when I run it from the stick or anywhere else on the desktop I get the same result.
