I know this has been mentioned before, but I wanted to see if any progress had been made for a fix now Win 7 is nearly a year old.
The problem is that the cache of Windows Explorer thumbnails of all the pictures on my PC gets deleted every day. So every day when I want to look at my picture library I have to wait for Windows to search through and make new thumbnails of all my pictures again. Up until now I have been using the work around posted all over the net of denying delete access for all the users on my PC to the appdata/local/microsoft/windows/explorer directory and files contained there. This stops the system processes from deleting the files and I get instant display of the thumbnails of my pictures all the time. But this is not a proper solution.
I was reminded of this problem recently when I reinstalled my OS and forgot to re-apply said work around. I let the latest version of live photo gallery find all the pictures in my library and make thumbnails for them. But the next day it started reprocessing them all over again. I then remembered I needed to block access to the directory above as live photo gallery seems to get it's thumbnails from the same cache files as Windows Explorer does.
Anyway over the past year I have heard various rumors that it was a bug Microsoft was working or that it was intentionally setup this way for some unknown reason. So I wanted to post this up to try and it get finally answered why Windows 7 behaves like this. So please can someone from Microsoft let us know what is going on with this issue.
Also if you same problem, please post in this thread so Microsoft can get an idea of how many people are affected by this. I would post links to all the places I have seen people discussing this problem, but I don't know if that would break any forum rules. Also I don;t know if this was the right Windows 7 sub forum to post this issue, so please move it if not.
