Thumbnails not showing in Explorer in Windows Vista

Recently my thumbnails for all image formats (except .ico) have stopped appearing in Explorer in Vista. I have unticked the "Always show icons never thumbnails" option in the Folder and Search options. I have set the visual effects to be for best appearance. I have reapplied the Aero theme. I have also tried deleting thumbs.db and the icon cache. I do not know what else to try. Any help?

    I have changed the setting to best performance, but the problem still exists.

    I have the same problem, however the only way I can get them back is to set organise/layout/preview and click on each image the next time you open the folder the thumbnails are back. However this is a long winded way of doing it but works.

    I have recently reinstalled Windows, and it is now working - I don't think I ever will know why it wasn't.

    Thanks for all the help, but no more answers needed :)

In the Advanced System Properties when you right click on (My) Computer, you probably set the Performance Settings to "Adjust for best performance". In there you will see a Custom List of options and "Show thumbnails instead of icons" needs to be checked.

Something I tried and it worked. Go to Tools/Folder options in the Explorer toolbar. If the " Always show icons never thumbnails" is unchecked ....try checking it....then apply and close. Then go back and uncheck it ....apply and close. Dont know why but this worked for me and this has been bugging me for ages.

Good luck.

Video thumbnails on my computer wont show up on laptop. The exact files on my PC show thumbnails of videos fine. Is there any software I have to download for my laptop to show the thumbnails?

Open the folder where the files are stored.
Click on 'Tools'
Click on 'Folder Options'
Click on the 'View' tab.
Check the box that says "Do not cache thumbnails"
Click ok.

I hope that fixes it.

I'm always being alerted that Com surrogate has stopped working

This might help:
Disable Thumbnail Previews in Windows Vista Explorer If you want to speed up browsing around in explorer, you might think about disabling thumbnail previews in folders.
To make this change, click the Organize button on any folder, and choose Folder and Search Options from the menu.
Click the View tab, and then check the Always show icons, never thumbnails checkbox.
Click OK, and you're done.

There are lots of people also pointing this problem to Divx, Nero and general codec packs but the problem starts when they start using a media player not windows explorer.

Give it a go and if it helps please rate me.

Windows Explorer sends continuously error messages

Turning off thumbnails will probably stop you getting that error

Open Control Panel > Folder Options > Always show Icons, Never Thumbnails

However, this isn't actually fixing the problem.

Do you have Nero installed by any chance?

If so try:
Open Computer > System Drive > Program files > Common Files > Ahead > DSfilter.
Rename "" to ""
Also rename "" to ""

And then reboot.

Windows xp sp3 problem

The most likely cause is that windows explorer is very busy or
has crashed entirely. It may actually refresh the icons if you wait an hour or ten.

One of the most common causes of explorer crashing are large malformed media files (such as downloaded movies) which are inside or below the current directory tree. When you click on a media file or a folder containing media files, Windows explorer scans the entire directory tree for media files in order to generate thumbnails and preview images. This can take a very long time, and if explorer gets stuck on a malformed file, it will totally freeze. Stopping and restarting explorer at that point, as you did, is the only escape, short of re-booting the machine.

In your case, explorer may touch some bad media files during the boot process.

Windows uses two DLL files to do this:
1) SHMEDIA.DLL (ie show media)
2) SHIMGVW.DLL (ie show image view)

You can enable and disable these DLL's on the fly, using:

regsvr32 [/u] dll-name

inside a command script = batch file *.bat

If you disable these DLLs you will not get thumbnails,
but your explorer will brows much faster, including
desktop refresh. (assuming you have media files in the tree)

This may fix your problem.

Explorer could also be waiting for the network or some physical device (could be a bad CD in the CD player)

Another trick is to hold down the control key when you menu start a program from the task manager, this launches DOS command mode with no explorer and bypasses many file locking restrictions.

Can you revert to SP-2 ?

(SP-3 is very recent and probably contains new bugs.)

I don't thing it's practical to troubleshoot the system after a major upgrade, looking through hundreds of thousands of registry entries.

Also, I am not sure that SP-3 is totally desirable, because it installs the complete set of updates, some of which are good for Microsoft and VERY bad for you. For example the latest media players are full of DRM (digital rights management = copy protection), and some the updates, such as WGA (Windows Genuine Advantage) notification are nothing more than spy-ware designed to identify, target and harass people with shady serial numbers. If you like that kind of abuse, you might as well go all the way and get Microsoft Vista.

You may also want to go into explorer options and disable
thumb nails cashing all together. Thumbnails are implemented
very badly in Windows, they are cumulative and contain every image within a directory FOR EVER, even after the original
image is long gone. Like an Elephant, the thumbnail database
always grows and never forgets. (a bit of a privacy risk !!!)

Good luck

Thumbnail generation

There is no known software compatibility with adobe premiere and vista. The problem will be that you might have changed any setting in vista for thumbnails. I know vista is much different than windows. So, have a look around at the settings.
