I found the cause of the misteriously disappearing Windows 7 desktop icons and the reason why Show desktop icons now and then gets unchecked.
It’s INFRARECORDER !! Try for yourselves, when you start Infrarecorder and close it again, go have a look at “Show desktop icons”, it is unchecked (but the icons are still there). Check it on again and start Infrarecorder…. it is unchecked again.
This Windows 7 “bug” is irritating me since the beginning and now I found the cause: It’s Infrarecorder which is causing this problem.
Test it, please let me know and spread the news
