Couple things to try to get your icons back.
First right click on the desktop, choose 'view', then make sure the checkbox is checked to 'show desktop icons'
Another which is known is caused by the free CD/DVD software called "Infrarecorder". Is that installed?
This is a CD\DVD recording software. When you install this software the Windows option to Show Desktop Icons is unselected. To Fix this just turn that option back on. If that corrects it, consider uninstalling it and using another recording software.
Hope this helps.
it is checkmarked, I use Ashampoo burning studio 6,, but that's been on my PC for ages and this problem is relatively new.
thanks for the suggestion
