Windows 10: Windows 10 Update KB343909 prevents seeing external hard drive

I dont know if this is already known, but general update for Windows 10 KB343909, just left me without access to any of my external drives (via USB).


To temp fix :-

Uninstall in the CMD window, using "wusa /uninstall /kb:343909"


Hopefully there will be another update soon to fix this. Windows are aware of this issue (that they have just caused)


Hope that is of help to other like myself who just spent an hour trying to figure out why I cant use my PC.


Cheers
