Oh, well, in that case I’ll leave you to it and shan’t bother to tell you the nastiest one yet …

Whereby you take a screenshot of a colleague’s desktop and set it as their machine’s wallpaper …

Move some … say 50% to 67% …of the icons on the desktop somewhere safe …

Lock the desktop so that icons can’t be moved …

Set the taskbar to autohide … and either set the animations to off, so that it simply reappears without any visual indication, or, if that’s not an option, set it to the narrowest of narrow sizes (say 1 pixel), so that it isn’t noticable.

Sometimes (33% to 50%) of the time, when they click on an icon on the desktop, it behaves as they expect, but 50% to 67% of the time nothing happens.

So the problem seems to be related to certain folders rather than the system as a whole … which slows the diagnostic procedure down as they investigate inappropriate causes and solutions.

And the behaviour of the taskbar is all the more frustrating if, some of the time clicking on an app brings it to the foreground (or minimises it) and … mysteriously … some of the time, it achieves nothing whatsoever.

But, you’re busy, trying to do other things …so, I’ll leave it for another time.
