I noticed several days ago when I had downloaded a file that it didn’t show up on my desktop where I had saved it. I thought I maybe inadvertently saved it somewhere else, so I proceeded to download again, selected the Desktop as the save to location, and clicked Save.
“Do you want to overwrite the file?” I thought that was weird. It’s there, but I can’t see it. I went back to my desktop, hit F5 and … BAM! It appeared.
So, I did a little searching and found that there is a Vista update for this. Knowledge Base Article 932406 “The Windows desktop may stop updating correctly after a Windows Vista-based computer has been running for an extended period of time” appeared.
Sure, I run my computer for extended periods of time, and my icons are AWOL. It seems to fit my scenario. So I downloaded it and installed. We’ll see how things go after the reboot.
Here’s the link to the knowledge base article.
