'This won't take long'

The above comment appears on a white screen and remains active.
However a split second later the normal browser/email screen appears to hide it.
Have had a few possible remedies on the MS forum...but no result....I'm told it is a Windows update problem.
Also told it creates no problem.

This appeared on our two desktops and a laptop at about the same time a couple of weeks ago.

All machines are clean and up to date etc.

Maybe its your internet speed causing the problem.

I do use Ookla which always shows around 36Mbps.
