Windows 8 "Personalize" my Desktop on Win8.0 MESSED up BIGTIME

[baobab]

I messed around for hours trying to "improve" my desktop!
WOW! What a mess.
I'll never hit that Personalize option after this
Please can you help me revert to the standard colours of a Windows desktop? ?
Many thanks,
baobab

Hi Boabab,
have you considered using system restore and going back to when Windows was running as it should?

No kemical, I would rather not do that because it will bring back a lot of the rubbish I've been cleaning out, and some other "improvements" will be lost. Isn't there a Windows standard theme to install? How does playing with "colors" like I did, mess everything up?

If you right click on the desktop, click personalise and then choose a default theme (I'm running win 10 so will look a little different to yours):
