Desktop Icon positions have been scrambled

I am a busy user of the PC, and have over 120 icons on my desktop. To make these easy to find, I group them in clusters, so that similar types are all together.

Last night I ran CCleaner, and it reset the entire desktop so that all icons are moved over to the left, and in random order.

I cannot find which item in the CC settings to uncheck so that it doesn't do this. I cannot find this in the Help Guide either.

Can anyone advise me please?

I have answered your other post here Philip.
