Soapy

I had tried most of them with no luck. One in that list that I had not tried is "Change The Default App". It worked when I tried the first step which was right click on an icon and select open with another app. When I opened it with an app that was different than my default (IrfanView) the most of the other thumbnails on the desktop were restored. I then repeated with another icon which restored more icons, and repeated that until all were restored. I did not change my default app, so I may have the same issue when I run CCleaner again. Thank you for your help.

After running CCleaner all of the thumbnails on my desktop and in folder have been replaced by icons. I've tried many of the tips for restoring thumbnail view and none have worked. Does CCleaner change something in the system to replace thumbnails with icons? If so, how do I restore the thumbnails?
