I have been fighting with this since I purchased this notebook with Windows 7 in 2010.
I do a lot of photo editing. I may have around 40K image files on my computer. When I am doing a lot of editing, a problem arises as the thumbnails do not update in window explorer. So, if I am working on several images and will open and reopen files, if I have made an improvement on a file, the thumbnail will not update and it gets confusing trying to find a picture that I have just edited.
I have sought suggestions on this issue a dozen different times. When I troll through forums, this is a common problem.
Here's a spoiler alert ... cleaning the thumbnail cache does not fix the problem. Matter of fact, here is a classic "cookbook" recipe on how to fix this from another forum ...
As usual, the answer is never found and the solutions move from the sublime to the ridiculous.
Since Bleeping is my favorite stop, I thought I would seek an answer here rather than letting Google find another false positive to my question.
