All icons, throughout my system (W10), have gone but description

Turned my computer back on this morning to find that all my desktop icons, most of the task bar icons and all file icons have gone, however, their function remains, as far as I can tell.
There is other weirdness in that I can right click on the icons but 'properties', for instance, will not work and when I go in 'This PC' weird black bits appear in the menu on the left. Also, when I save to my E: drive, I can actually see my file icons displayed in the 'Save as' box but not when I actually navigate to the drive, only the description below where the icons should be.

The last thing I did before turning the PC off last night was run Super AntiSpyware and Spyware Terminator and then play a bit of Battlefield 1.

The only thing I've done to try and rectify this is do a restore to two days ago but it has had no effect.

What has happened and how can I rectify it?

Thanks,
Tom.

Spunk,
Thanks. Just tried it but it doesn't give me the option to open a command windows.
Is it Powershell?

Thought I'd create a system restore point before trying Winaero Tweaker and this happened.

Tom.

Nope, tried the Winaero Icon Cache reset and nothing happened apart from the taskbar blinking every time I clicked 'Reset Icon Cache'.

No luck with option 1 or 2. I've posted in Barman's suggested thread.
