On the System page in Control Panel, click Advanced system
settings, and then in the Performance box, click Settings. Turn off the
Show thumbnails instead of icons option, and click OK.
Next, open the folder and then test each of your media files. The video
that won??™t play or the photo that won??™t display is the likely culprit. Now
it??™s just a matter of figuring out whether the file is corrupt, or the codec
needs to be fixed, as described in the beginning of Chapter 4.
Slow network access
When you open the Network folder to view other PCs on your LAN,
Windows Explorer sometimes takes a long time to show them all. See
Chapters 7 and 8, specifically ???Stop Sharing Scheduled Tasks,??? in
Chapter 8, for help troubleshooting network connections and shared
folders.

Troubleshooting
Searching when files are changing
If you??™re searching a folder, especially if you??™re using the Include nonindexed
option as described in Chapter 2, and another program is writing
files to that folder, the search results may repeatedly appear and disappear
while you stare at the green progress bar. To solve this problem,
close the Search window (or select a real folder in the tree) while programs
are saving files to your hard disk.
Copying files
Vista is hopelessly slow at copying files in certain situations, two in fact.
(More on this in Chapter 2.)
First, Vista??™s UAC feature forces Windows Explorer to evaluate the
security impact of each file you copy, and this has far-reaching consequences,
particularly when you??™re copying files over a network.
