X200 and X201 System Update updates itself and vanishes

[Billaboard]

As per heading, on a couple of machines "Lenovo System Update" is started and sends a message saying there is a new version.

When updated, all the shortcuts to it on the desktop, start menu and taskbar disappear.

OK, I've dug around and made a shortcut on the desktop to tvsu.exe, but surely this is not good.

The whole Windows thing seems to be turning into a mess. Lenovo Companion has appeared out of the blue but doesn't work properly on the Windows 10 machines. Microsoft Update on a W7 X201 has been sitting at the "Checking for Updates" stage for 45 minutes now.

It's bad enough keeping up when the system works, but this is beyond a joke......
