In Windows XP, there used to be a folder setting like "Do not cache thumbnails." I can't seem to find something similar for Windows Vista and Windows 7, and every folder on my network containing a photo or video continues to get littered with "Thumbs.db". I appreciate that caching thumbnails makes some sense, but I still would like to turn this off because I also value not having litter in my network folders.

What's the easiest/quickest way to solve this problem?

Update 1: Here's a link to Wikipedia's info about the Windows thumbnail cache.

Update 2: My solution is below and now includes a registry equivalent that you can save in a .REG file for simpler application to any of your Windows Vista or Windows 7 boxes.

Using Group Policies

So, with more specific googling, I've discovered how to do it from a post here, for editions of Vista and Windows 7 that come with Group Policy Editor. (Unfortunately, GPE doesn't come with Windows 7 Starter, Home Basic, or Home Premium. A solution for these operating systems can be found in the second part of this answer.)

Here are my own detailed instructions, written against Windows 7 but likely the same for Vista:

  1. Run gpedit.msc directly using the Start menu. (You may also be able to find an Edit group policy control panel searching by name, but I couldn't find its icon listed anywhere under "All Control Panel Items". Go figure!)
  2. In the left-hand pane, expand User Configuration, then Administrative Templates, then Windows Components.
  3. Under Windows Components what was just expanded, select Windows Explorer.
  4. In the right-hand pane, sort by Setting, then scroll down and find the setting named "Turn off the caching of thumbnails in hidden thumbs.db files". Double-click it, set it to Enabled, and then click Apply.
  5. Log off Windows, and then log back on again.

Within Windows Explorer, you should now be able to delete the Thumbs.db files that you come across on the network (as long as another machine isn't currently locking the file), and the computer shouldn't create them again.

Also worth knowing: In Vista and Windows 7, Thumbs.db applies to network folders only. For local folders, Vista and Windows 7 instead save thumbnail cache information to a database in a local folder at %userprofile%\AppData\Local\Microsoft\Windows\Explorer

Using the registry

The registry equivalent for disabling Thumbs.db creation on network shares in Windows Vista and Windows 7 is:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer]
"DisableThumbsDBOnNetworkFolders"=dword:00000001

If you place that content in its own text file (e.g. with Notepad) with a .reg extension, you can double-click to import on any Windows Vista or Windows 7 machine to apply the setting. Be careful editing your registry directly.

Thumbs.db is a hidden file, so the easiest way to not see it as litter would be to simply tell Windows to not show hidden files. Of course if you use the command line a lot or have other hidden files you need to see then this won't help.

I found an article that mentions the ability to disable thumbnail caching by modifying a registry key. If the option to disable thumbnail caching is missing in Vista / Windows 7 then maybe you can still do it that way.

  1. Open the Registry Editor (regedit.exe).

  2. Navigate to the following registry branch:

    HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Explorer\Advanced\

  3. On the right pane, double click on DisableThumbnailCache value, and set its value data as 1. If the registry key of DisableThumbnailCache does not exists, create a new DWORD value with that name.
  4. Exit Registry Editor.
  5. Logoff and login again, or restart the computer for the changes to take effect.

Another option may be to simply turn off the display of thumbnail previews in Windows Explorer:

  1. Click on the Start button, then on All Programs, follow by Accessories.
  2. Run Windows Explorer.
  3. In Windows Explorer window, click on Organize button on the menu/shortcut bar.
  4. In the pull down menu, click on Folder and Search Options.
  5. Folder Options dialog window will appear. Click on View tab.
  6. Under the Files and Folders tree heading, check (tick) the checkbox next to Always show icons, never thumbnails option.
  7. Click the OK button.

There's a registry key you can change to turn off thumbnail caching.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced\DisableThumbnailCache

Set it to 1 to disable caching.

Details here.

I generally keep hidden files hidden and unhide them if I need to grab something. The Thumbs.db files are annoying, yes, but they can speed up folder load times.

If windows had to re-generated all those thumbnails every time every media folder loaded I'd be in trouble.

If you turn off the thumbnail cache, I'd recommend changing the display to "list" and reset all folders to use that mode from the Tools -> Folder Options -> View menu.

NB: The tools menu is still there in Windows 7, just hit "Alt" in an explorer window.

Hate to necro this thread, but it's lacking an all inclusive answer:

Merge the following registry script into your Windows 7 registry to disable thumbnail caching in local folders and network folders:

Windows Registry Editor Version 5.00

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer]
"NoThumbnailCache"=dword:00000001

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer]
"DisableThumbsDBOnNetworkFolders"=dword:00000001

Following the guide found on this Microsoft page we can learn about the command attrib

If I have a folder with pictures and I don't want to see the file Thumbs.db, you can open CMDwith admin rights, and then to change to the folder path just do cd, example: 

cd C:\Users\"YourUserName"\Pictures\"NameOfTheFolder"

To hide all Thumbs.db files on that directory and any other subfolder do:

attrib +s +h *Thumbs.db /s

In Windows 7 Explorer (the standard "files and folders" viewer):

Organize -> "Folder and search options" -> View -> "Always show icons, never thumbnails"

I don't know precisely how broadly this is applied, but it seems to have done the trick for me.

The thumbs.db GPO (Group Policy Object) path is different depending on the operating system:

GPO path:

Administrative Template pre-Windows 8/ pre-Windows Server 2012:

User Configuration > Administrative Templates > Windows Components > Windows Explorer

Administrative Template Windows 8 / Windows Server 2012 or higher: 

User Configuration > Administrative Templates > Windows Components > File Explorer

GPO items:

Turn off the display of thumbnails and only display icons on network folders

Turn off the catching of thumbnails in hidden thumbs.db files
